B9 S4 - The Carnage, The Current and The Future Build Thread

[East_Coast_S4]

What's going on AZ Fam - Most of you actives and lurkers from the standard B9 Groups/Forums etc are familiar with my car and some/most of the story of things that happened. A lot of it got washed out in the locked/deleted/hidden EPL Drama threads so I would like to start a fresh new discussion that mostly moves away from the EPL crap and towards the future of not only my build but Discussion from anyone that is moving forward on the B9 platform past what we currently have available in standard Stage 1 2 or 3+ Flavors.

If you don't know me or are newer here - My IG is East_Coast_S4. I bought my 2019 S4 PP literally on Pandemic Day March 14th 2020 and almost immediately started getting into the mods. I mailed my ECU off to EPL to be bench flashed and worked closely with Tony for those 2+ years as one of the main Beta testers. I helped set the bar multiple times for records and held the stock turbo full weight quarter mile record of 11.13 @ 121mph for almost a year before I think it was broken. Not being satisfied I moved right into going to TTE710 and upgraded HPFP early summer 2021. With EPL it was all downhill from there. The communication with EPL/Tony degraded severely over the next 6 months as he was "Tuning Remotely" for the majority of the year. Issues were prevalent with fueling and other than releasing some highly coveted features like Antilag and specialized hard cut launch which are still unmatched by the competition we just couldn't push past the base maps for most of us. Some people were able to get a few good runs on some low E blends or 104 Octane tunes but we all had serious backfires and stuttering across the board. I continued to relay feedback and log with Tony through this and tried to stick by them but eventually the issues and my piston rings went Ejecto Seato Cuz.

Long story short EPL had some other issues on their hands, mix of business and personal and closed up shop. It was an entire forum debacle and I was left hanging on broken promises and starting my rebuild over again after being strung along for almost 4 months.

Right as this story broke Tyler at IE reached out to me - We talked about the situation briefly, but quickly moved on to discussions of future plans and positivity given the scenario for both my own build and things they were working on in house and upcoming for the future of the B9 platform. Expressed interest in working with me since I was rebuilding with forged goodies and looking to continue pushing for records and see where this EA839 could go. I gladly accepted and started ordering parts ASAP.


As most of us know both Mario stateside and TK across the pond have put in some serious work on opening up the possibilities for future development on these cars. I am currently not digging as far into custom territory as them as I just don't want to be the first to pop..again - but as many of you I watch with anticipation for the next big update from both.


I will be posting some details and pictures of the carnage. Things that were tested and ruled out as causation and welcome a proactive discussion on theories but I no longer care to live in the past or bother talking about what if/what was or why etc and largely just want to keep a drama free thread discussion open for us here.

I will update the parts I am using and details as I can provide working with IE. I am super excited at some of the things they are working on in development and can't wait to work more with Tyler and Carter as I have gotten some time to chat with them both over the last couple months. **KEEP AN EYE OUT FOR WHAT IE COMES TO PLAY WITH AT SEMA **


The car is finally in rebuild mode and should actually be on the road in the next ~2 weeks.

Big thanks to TK for all the research and hours he has put in, I have picked his brain more than a few times and discussed lots of options and plans for where we can go with what is available. I will be starting out with the built bottom end and TTE710 that I've already got and going with IE Stage 3+. As they are wrapping up the Pure750 files they will be moving on to TTE810 tuning. If it proves a solid upgrade I might send off my stock turbo to be upgraded otherwise I would ultimately like to move into full frame big boost territory as soon as we have a direct upgrade path available. Though in general I am against stripping out a luxury car just to set records and times I will go ahead and have a "Track Day" setup. IE is working on multiple upgrades and components to help with both performance and weight reduction. I am fine with removing passenger seats for the weekend and will be getting a track wheel setup etc. I plan to go with likely carbon fiber hood/trunk/fenders for a chunk of my weight redux as I will never strip door cards or other random items out of the car just to save a few lbs.

For Rods Pistons and Bolts I went with Italian Rods & Pistons "Gold" Line secured stateside by Andrew at ORT Motorsports.
I currently have the ORT HPFP but IE internals should be available very soon and will be switching to that as well as the RS Injectors for Stage 3+ E70 setup.
Euromotive Autohaus in Eastern PA has been super patient and solid to work with during this long process and they are the shop managing the rebuild.

I did send out my rotating assembly to another shop to be polished and balanced. This is a super high end race build block shop that builds 3,000HP+ monster blocks however they didn't have the weights to fit into our assembly due ultimately to light weight design and the way our rods fit. Though they polished the crank and weighed all the components they were very enthusiastic about the build quality of the rods and piston and found they all were within a single GRAM of weight of each other. They assured I would be rock solid as is.
I would have loved to do some headwork and valvetrain upgrades for future but just isn't in the cards right now and Mario wouldn't share his supplier nor sell me anything from his builds. At some point ill come back to that.


Now on to W T F HAPPENED?! So many people speculated that I just drove around like a bat out of hell 24/7 and didn't take care of my car, I beat on it and destroyed it and ultimately it was my fault. To that I say we all ran numerous launches and logs if you were in the EPL group. I cared for the car meticulously, I logged regular and I monitored as much as I could between P3 and VCDS when there were issues on top of sending literally dozens of logs to Tony on a regular. I used only premium or OEM products and meticulously modded my car with the best parts available on the market. At the end of the day...shit happens and I'm ok with it but the fact is that both 034 and IE are out here running cars on stage 3+ with about 100whp more than I was ever running with Tony not to mention Mario showing stock blocks pushing 675+whp without imploding. The car is 2019 with 35k miles - Personal abuse just simply wasn't the case.

Others speculated I had a failed PCV system and continued driving the car after having issues related to that. Again not the case, I never had any issues and my oil cap only came off because cylinders 4&5 had blown out pushing pressure right through to the crankcase. I had my hose switched out via the TSB literally the same month it came out in 2020 which included the updated T valve that has failed for others. I also tested functionality of the entire PCV system with air and vacuum while it was off the car. The valve works exactly as expected. Tony suspected failed rings even though many builders have commented about the major upgrade in quality of the rings over B8s not to mention sleeved cylinders should provide a solid home to push more power than a B8 ever has safely. The rings were not the fail point even though you can see them below totally mangled on Piston # 5. Tony also suspected failed injectors and/or LPFP not providing enough flow - Though I wanted to have my injectors fully GDI tested at actual operating PSI I was not able to complete this in time as the shop I planned to use simply failed to respond. However these injectors were cleaned and inspected and found to not show any signs of failure at all. Multiple other tuners have confirmed that the LPFP is in no way maxing out or the weak link in our setup even on these latest Stage 3+ files that are again pushing 100whp more than Tony was able to achieve via his remote tuning methods.

With all the stuttering and multiple major backfires from the tune problems I suspected those played a big part in weakening the pistons / landings though to my knowledge detonation problems are generally seen on top of the piston. The tops of mine as well as the walls were near pristine condition and the valvetrain showed zero signs of stress or issue. I assume due to the fueling issues, pressure and temperate and likely lean conditions the ring lands pinched the rings and started whatever led to them throwing chunks down into my oil pan which thankfully the oil pump screen saved from going any further as shown in the picture.

If any engine builders or otherwise professionals want to chime in on what they see from the pictures feel free - Piston #5 totally destroyed the rings and blew chunks and #4 had a few major stress cracks that once actually picked up the 2nd time fell apart in a similar way.

I will post some engine rebuild photos and stuff over the next couple weeks and keep updated with the real world performance of the IE tunes as a few others have lately vs a pure track only setup. I would also like to share my own thoughts on IE tune and overall drivability vs my couple years experience with EPL on all aspects of daily and spirited driving as well as track day stuff.

I welcome anyone else looking to push past standard hybrid turbo builds to join in, share your pictures ideas and finds on what's coming next to keep pushing these boundaries I know I have talked to a couple people in the community looking to move to built block territory as well.

LETS GO!

[AldermanToffee]

Super glad to see IE’s dedication to this platform, I’m very excited to see what they bring to the table alongside 034.

Any plans on running nitrous with the built block by any chance? This is something I have looked into myself but wouldn’t be touching until DS1 becomes available along with their “Project SABRE” function on MG1.

[SHCKR]

And add more photos!

[CELison]

Backfires don't melt pistons. That looks like it ran very lean and what you were experiencing was most likely lean misfires. Also, in the other thread you started I said something about Mario tearing down this motor and you denied that was the case. But now you're saying it is? Story sure changes a lot.

No Doubt! I would have to say it is a very likely scenario that some big ol blue bottles of go go juice come in to play at some point!

And add more photos!

Yea man, I've got some photos of the initial tear down I can add - My shop is definitely getting me vids/pics of the rebuild and between here and IG ill be adding those too!

I would typically agree however unless EPL really did have the knock sensors turned down as much as some other tuners have claimed I never had any knocks in my logs or misfire codes until the actual implosion event. Then again I suppose it just takes one cold winter night running lean to go boom and that's what happened I guess

No sir - I am quite meticulous in my responses and have never altered my story. As you can see by my longwinded wall of text above I try to give all the details I can to welcome discussion. I discussed multiple things with Mario over this year, including possibly doing my rebuild and/or future work but he has never had his hands on my block. That mangled block he posted was not EPL tuned though I have my speculations on whose it was he will never confirm.

My build shop is Euromotive Autohaus in PA - About 4 states south of where Mario's shop is

[oesman]

Wow, definitely would like to hear more about that. That's kind of a big deal. In my opinion turning down the knock sensor response is at best a band-aid on a case-by-case basis with a car that has a false knock problem. Once you're 100% sure the knock isn't responding to the sensors reducing timing AND your fueling and fuel quality are on point. Like if you have great AFRs and your boost levels look good and you are on say race gas and still have knock sensors going off and the resulting timing retard doesn't stop the knock sensors from going off, ok maybe... but really figuring out why there's false knock is the better plan whenever possible.

Yea - So I don't condone ripping other peoples code/tune through a hex editor but fact is this day and age its going to happen. According to Tony his map switching setup encrypted everything behind it and nobody would be able to see anything but stock tune settings (default map 1) however word on the street a while back was that there were some prying eyes into tunes and it was claimed that EPL was running dangerously lean in some areas and that knock sensors were retarded to sketchy low levels. I won't speculate any further as I don't want to spread misinformation and I have no way of being sure other than fried pistons when my AFRs always showed what I thought was solid on the P3 gauge (I usually kept mine on AFR vs other things)

The only time I ever had any knocks show up in logs / VCDS scans etc on my car was early 2021 when I was chasing down some major power loss and ended up finding that the nuts on my DP had completely backed off the studs because I reused the copper hardware that had come with my Redstar DP when I switched to the Carbnlab. I put some proper hardware on and retorqued my entire exhaust setup and never had another peep on that note.

[CELison]

I wouldn't run anything beyond a stock turbo without proper monitoring in real time. My b5 has a boost gauge, AFR gauge, and E content gauge all in the center vents and I have a fuel pressure gauge I can rig up and run in the cabin for diagnosing issues. There's no way I would feel comfortable without those at the power level that car is at. I don't like that I don't know boost/afr in my b9, but it's just a commuter with a tune and some bolt-ons so I'm currently rolling the dice.

[oesman]

Interesting on the whole knock sensors and lean thing.

As for monitoring, I agree. It's like my mustang setup (supercharged), have a dedicated boost gauge, fuel pressure gauge and then this monitor which can data log and flash tunes:

If the readings turn red while in PE then something bad is happening. if they're green then good things are happening (extra timing, good AFRs, etc..)

[AldermanToffee]

Eh, these ECUs will respond quicker to lean conditions / over boost / knock than a human trying to read gauges at 130mph+ will.

They however won’t do that if the tune has those safety strategies disabled though.. Mario read a Stage 3 EPL tune and the knock sensors were massively desensitised. We still have the photos of the knock thresholds in a group chat somewhere.

Boost/vac is critical to know for boost leaks, vac leaks, WG issues, ect. ECU isn't going to tell me if boost or vac has increased/decreased a small amount or AFR has changed a small amount. But it can be seen on a gauge and used to diagnose.

[East_Coast_S4]

Yea my only caveat of the P3 is that I can only see one thing at a time and it will only show a short memory of one reading at a time - I definitely would prefer something more like the NGAUGE that can show multiple variables at once with warning lights to your settings.

P3 monitors: Boost (through OBD2 port using OEM sensors or with P3 analog boost sensor)
Coolant temperature
Air/Fuel ratio (can be read in AFR or Lambda)
Vehicle speed (can be calibrated in 1% increments from -9% to +20%)
Intake air temperature
Throttle angle
Ignition timing
Engine RPM
Exhaust gas temperature
Battery voltage
Programmable shift light

I will probably add an analog boost tap in but I have been using this gauge as well as regular VCDS/EPL Cable logging pretty much the entire time I have been Hybrid turbo especially on launches or WOT pulls. I also have had the Fuel IT bluetooth ethanol reader in since the first time I started running E blends

So I will definitely admit I am very new to understanding engine at load metrics like what AFR is good for what application etc - This is my first deep dive into real tuning and modding of a more sophisticated vehicle. I found it pretty odd that it was claimed EPL ran lean on their tunes when my P3 showed almost always a 12.0-12.5 AFR on WOT. So here is my thinking maybe you can shed some light on what I know currently.

13 and below is rich
14.5 is spot on
15+ is pushing lean

However does this account for Ethanol blends in a standard ECU sensor? Say I am running E50. Ethanol in general needs ~30% more volume for the same efficacy so while my car read dead on 12.0-12.5 AFR almost always on WOT was it accounting for that extra fuel volume or was it thinking I was running rich because of the extra volume of fuel when I was really running closer to lean in this scenario ? I have NEVER seen AFR in the high 14s+ on EPL tune while more than 60% throttle

[oesman]

Eh, these ECUs will respond quicker to lean conditions / over boost / knock than a human trying to read gauges at 130mph+ will.

Oh for sure and so will the mustang's ecu, it's a fairly advanced unit as well. That car is also very fast, around 1kwhp on a good day ;), so you're more worried about not dying than reading gauges. But if you see red out of the corner of your eye you can pop off the throttle (audible alarm would be better) and you can also know to check data logs from the device.

Also I will 100% do test rips at lower speeds while looking at gauges to make sure that they go green under PE if I've changed anything or it's been a minute since I've driven it and I wanna make sure my fuel is still good. Plus I can then flash it via the same gauge to one of my lower power tunes and limp home if I have to.

P3 monitors

I'm not impressed with the P3 at all, definitely not buying one. It's like a kiddie version of the nGauge I have in the mustang. I'm looking at other options to replicate what the nGauge is doing and there are promising things coming to the platform it sounds like with VCDS level built-in logging.

14.7:1 (stoich) is what you want for idle/cruise. That's way too lean in boost. Pump gas WOT you want ~11.8:1 on most turbo cars. E85 WOT you can get away with a little leaner, my tuner targets 12.0-12.2:1. Again, these are general and each platform/car config might like to operate at a little different AFR.

[oesman]

Again, these are general and each platform/car config might like to operate at a little different AFR.

Yea its definitely platform dependent. I'm seeing AFRs that aren't very rich at all when data logging my 034 tune. Talked to their people and they said it's normal for these cars. On pump 93 I'm seeing at the lowest like 12.5:1-ish. Most of a pull through a gear is 13:1 or higher. But actual is meeting commanded, so car is doing what the tune is telling it to do.

Keep in mind stoich is fuel dependent. 14.7:1 is the AFR of gasoline. E10 will be a little bit lower (14.08:1), E85 much lower (9.85:1). This is why it's good to look at lambda equivalence ratios, i.e. under 1.0 is rich, over 1.0 is lean. This is the way data from the oxygen sensors is interpreted by the ECU. Say you read lambda of 0.8 you take 0.8 and multiply it against the stoich afr of your specific fuel, so if it's gasoline 0.8 * 14.7 = 11.76:1 AFR. If it's E85 then 0.8 * 9.8526 = 7.88:1 AFR.

That's the cool thing, theoretically your fuel can change but lambda 1.0 is still stoich no matter what. It means all the fuel combusted successfully and there wasn't extra air (lean) or extra fuel (rich) seen by the downstream 02s. Ultimately lambda readings are the best kind of readings to look at.

These cars don’t target a specific AFR, so slightly moot point in regards to that.

Boost leaks and such I do agree with though, but I still don’t think it’s necessary for a load of analogue gauges. My point is doing data logs periodically is a much more useful idea.

Yep, having data definitely doesn’t hurt but the tuner can also set up strategies that cut throttle / boost when they exceed their hysteresis limits. The issue with Donnie’s car is that the tuner had.. well, essentially removed / dampened these limits.

Yep and that car is much the same way, it's all fly by wire so while it can't mechanically cut boost (s/c on a belt) it can cut throttle and even just shut the engine off. I had that happen once, scared the shit out of me. A very small amount of unmetered air caused it during a pull.

Boost leaks and such I do agree with though, but I still don’t think it’s necessary for a load of analogue gauges. My point is doing data logs periodically is a much more useful idea.

You still want to know AFR is real time is my point. I watched my fuel pump die in real time because I have a wideband. If I were to run logs periodically, it would have melted down prior to that happening. I want to be able to look over and see certain parameters, not run logs once a month and hope everything is fine in between. If I'm doing a long pull, I always glance over at my wideband at least once. The more aftermarket hardware you throw at a car, the greater a chance you have at a failure, and I want to catch that as early as possible.

[East_Coast_S4]

Here is some pictures I took a while back when the engine was being broken down - Again super lucky that what did break off shot straight through the crankcase into the oil pan and sat at the pump screen basically.

I was so shocked that cylinder 5 looked so clean. I honestly thought I was going to have to get at least that bank resleeved.


I should be getting some updated rebuild pics and vids sometime next week and im hoping my builder decides to just go all in and get er done so I can start the break in period next weekend.

Managed to get her back on the road? I’m keeping my eyes peeled for IE at SEMA.

Nah man, The shop is taking on way more than they can handle or something and feeding excuses left and right unfortunately. It should be done soon though.

It's slowly making it back together.

SEMA is definitely going to be something special finally almost there.

What's Going on out there Audi Fam - I haven't updated this in a while because I have been pretty busy with life/work etc and I wanted to get some real seat time in with the current setup. Plus I had a few problems to sort out but the car is very much alive and roaring again!

I have some more pics I think of the final rebuild that I can get up but again after the EPL debacle my engine was rebuilt with IRP Forged Pistons & Rods. Sadly I couldn't source valvetrain things in time and am a bit bummed as I think I will want some minor head porting and valve spring upgrade for future ideas.

As mentioned Tyler from IE reached out pretty much Day 1 of me announcing the big EPL mess and they wanted to help get me back on the road and get some true input as well as work on continuing to move forward with the platform. I can't thank Tyler and IE enough so here is my official update.


After the rebuild I got my car back about a month ago, I had a minor coolant issue prior to this issue which turned into a major after. My coolant cutoff valve failed and busted the housing and was leaking coolant also essentially the shop missed a rear hose clamp so anytime I got on the throttle I was giving the losers a big smoke screen of coolant spray behind me Even though the car felt great I had to get that resolved. Decided to upgrade the thermostat and seal to latest revision while I was in the and car is now solid no coolant leaks and feeling better than ever with about 1k miles on the block on IE Stage 3 93 with TCU.

Let me just say that this IE is hands down more refined than any file I ever had with EPL. The tune is much stronger and absolutely ZERO fuel issues, the numbers look great and the drivability is night and day. I am running the same hardware I was but pushing what another ~100HP over what Tony/EPLs Hybrid files were on 93? Bravo first off on the tune, it is fantastic and even though I haven't launched or gotten draggy numbers in my crazy negative DA just driving this thing again daily has reminded me why I loved this car so much. Now on to the TCU - WOW....I was never honestly impressed with EPLs TCU remap, it didn't do much and he didn't even adjust shift points. It was what it was and we liked the LC etc features the most....

IEs TCU tune is by far night and day more refined - I LOVE the way it drives when I am being calm, highway cruising and the behavior between Drive & Sport. I love the fact that it goes for economic shifting all the way through S8 in sport mode on highway but quickly gets where it needs to go with throttle input. When I want the power it is CRAZY snappy and very satisfying. I held off on giving this feedback because I truly wanted a few weeks / 1k miles on this tune since I spent almost 2 years with EPL. With EPL I almost ALWAYS drove in (M)anual mode as I hated the way it shifted and preferred to do it myself, I NEVER drove in (D)rive as it was flat out horrible and had some weird surge and (S)port was just what it was.

I have had to break that habit I never feel a need to shift manually with IE TCU - It does what I want through the pedal perfectly, when I want to snap the burbles off driving in regular (D) is just as satisfying and I actually get solid MPG which is nuts...EPL I was NEVER over 20mpg and I break that easily with IE on the way to work every morning 22-24mpg. I have given my kudos to IE Tyler and their Calibrator directly but just wow every day I smile driving just loving this car again and the fact I can drive it how I want when I want and get exactly the response I want.


As far as future I planned to be running the E70 files by now but unfortunately IE is still testing their HPFP. I know I could run 034/APR/VIS but the last two I flat out refuse and though I am sure 034 current piston setup is good IE will be just a tad better as their kit will also include a replaced collar and replaceable O ring as I understand. Since this seal is the most common failure point of HPFPs it is a big thing to me to be able to order a new Seal/Ring instead of a whole new pump as someone with the other solutions would have to.....SOOO I have had my injectors sitting in the box for months and I have also ordered a TTE810 just waiting for the final piece of the puzzle to go all the way with current IE offerings.

As far as the future of this B9 build I personally want to end up full frame and big boy territory - I didn't build the bottom end for nothing, but I am going to hang with IE for the time being. I am told they are nowhere near done with the B9 platform and have a lot of future plans so I want to work with them and see where we end up throughout 2023! I have thought about just going ahead and buying the 034 tune as well and doing a comparison but tbh enough of the influencers and guys out there have already compared those two and I am just that damn happy with IE right now that I'm not sure if I will - Even though it seems they squeezed a few extra HP out of their new 810 files, if there is room to spare I am sure IE will continue evolving their files as well.

I would love to see others E70 TTE710 / Pure750 and TTE810 results and experiences on this thread...discussions of AFR with the fueling and thoughts of future plans etc. I am sure we all keep an eye on Mario and TK builds but surely others out there have some ideas maybe some newcomers to the platform. Also feel free to ask anything else regarding my setup and woes dealing with a rebuild.

Glad to hear it’s running again. Did you end up getting the crank balanced?

Also, any noticeable piston slap when the engine isn’t up to temp?

Yes they ended up rebalancing everything.. It is definitely a bit chatty on idle sounds exactly like injectors but louder than usual

Thought that would be the case, good to know.

Glad you’re back up and with IE. I also chose them over 034 and have been loving the stage 2. I’m also waiting on their HPFP before going to stage 3.. howver I won’t be doing injectors and will be running on 93 exclusively.
