11.948 at 113mph - B8.5 S4 DSG with Unitronic Stage II+ and Injen intake on 93 octane

[bhvrdr]

Today I received a Unitronic+ dongle in the mail and I had to try it out.


The Unitronic Uniconnect+ flashing interface is a really professional looking interface. It requires no support and is completely hassle free. <<<<EDIT>>> This interface automatically detects your stock software box code and the proper revision and it automatically has all files that should be available to you stored in the flash screen for you to choose from. Evil_O did a really nice writeup on their interface if you havent looked at it...

I accomplished my initial flash within 15 minutes of unpacking the cable. Once I was flashed I headed out for some logging and torture testing. Here is a run group of logs. Everything looked as expected. I uploaded the more aggressive 93 octane file that is suggested for those with upgraded intercooling. During the summer I may back down to their less aggressive 93 octane file. Choices are good.

Once everything logged out safely, I looked at the time and realized our local 1/4 mile track opened for test'n'tune in an hour. I normally wouldnt go on a Friday but I had to. Here were the results...

Car: 2015 S4 DSG

Unitronic Stage 2+ Flash
2.266" Pulley
Injen Intake

all else stock. 93 octane pump fuel.


11.948 at 113.38mph




Yes, this is the same trap speed as with the Chipwerke Stage 2. That was not shocking in that the performance logs from both setups showed the bypass valve completely closed and the car making decent timing. Subjectively, there is zero jerkiness under any throttle conditions. There was a bit of jerkiness under part throttle load with the CW. In addition, with the Unitronic the air fuel curve is slightly richer down lower in the rev range than the OEM fuel curve which I admit I likely would have done as well if I were able to calibrate it so that is nice for heat mitigation. Overall I am very pleased with the tune and the flashing interface has exceeded my expectations. I am anxiously awaiting a DSG tune from Unitronic as this is the one area my car continues to suffer shifting at 6400rpm.

Nice runs, and times. The logs look good from what I can see (looking on my phone). What was the DA and ambient temps? I do think a coolant system would help with IAT's where it starts to pull a little timing. Obviously, that amount is perfectly fine, but it may creep up in the FL heat.

[bhvrdr]

Thanks man. Yeah, i'll probably back down to the less aggressive file in the summer or else try some other ideas i've had floating around for reducing IATs. We'll see.

DA: 107 feet

Were the logs just 3rd gear pulls in those types of conditions? They didn't look like the drag strip. I do my baseline logging at around 60F ambient, and manage to keep IAT's in the low 50's after 4-5 back-to-back 3rd gear pulls. You were creeping into the low 60's. Obviously a lot goes into IAT's, but it seems like you're seeing a pretty good jump in what sound like pretty good conditions. I don't think it's hurting your times now (hard to beat those), but when it gets hotter maybe.

[DGVR6]

Nice! I wonder how it would pair with a TCU tune. Good time

[s4buckeye]

nice work son

Thanks guys.

Yeah the datalogs were 3rd gear pulls back to back. I'm not sure what can be done about the IATs without me making the choice to start to go more all out with this car. I started out thinking i'll keep the car for 1 year so doing just reversible bang for the buck mods but now i'm thinking I may even keep it as a track car as the value of it drops, lol. BTW, here is a car in the same test area with very similar stage 2 mods but this car has the AWE coldfront upgraded intercooling...

If I decide to keep it I really would like to look into fabbing up an air to air intake manifold and deleting our air to water setup. I'd also like to look at fabbing up a phenolic spacer. No water/meth or killer chiller for me as I want something dead reliable and lap day oriented. We'll see.

Congratulations Mike !

And thanks a lot for all the things you shared in this forum !
I would relly apreciate to have such drag racing tracks here in France, just for fun and to have "official" mesurements.
A flash at home is also a verry nice feature...

Best regards,

That's some really good times, and you say that the transmission is smooth? I get the jerky shifts so not sure if there is something not right with my tune. I'll login to Unitronic and see if there's an update.

[Loe]

Great time! You should drop a good .2 and gain 2 mph with a DSG file (which may actually place you in the #1 spot for a stage 2 on pump 93 octane).

[torinalth]

very nice. why the selection of uni vs the others?

[ptper]

Thanks for posting up. Awesome time for 93, and congratulations man! By aggressive file, do you mean a 100/104 map?

[Motown_Dub]

Holy smokes Mike! You've been all over the place, APR, Chipwerke, and now Uni. What's next an R8 engine swap?

I'm moving to a flash at home solution as well.

Keep in mind I only have about 50 miles on it right now but yes it has been very smooth. I'll keep you up to date if I notice something. I am a 2015 MY car too so you and I have different programs.

I like trying things out. This time I really wanted to try out a flash from home option. If I had wanted to immediately see what the limits of speed for my car are right now I would have flashed the GIAC ECU and TCU tune combo. They seem to marry together very well and I already have the AWE pulley but their dealership is a bit out of the way and I really wanted to flash from home. If Uni can get me some DSG software soon, it would likely be a wash at that point.

Thanks for posting up. Awesome time for 93, and congratulations man! By aggressive file, do you mean a 100/104 map?

No, it's still a 93 octane file but Uni has two files for 93 octane....one for standard intercooling and one for upgraded intercooling. I can only assume there are slight differences to timing between the two but I havent logged them both so I would only be speculating.


Thanks to the rest for the kind words.

I definitely understand your dilemma.

It's a little hard to compare the logs since he's revving so much higher but they look pretty similar. My biggest take away from that is the amount he's bypassing with everything else being pretty normal (less timing than I've seen on other Revo cars). I would have expected lower IAT's and no bypass.... I think that pretty much explains why he is 0.2 seconds off your time.

[will13k7]

love it, 93 tune + intake, nice conditions, in the 11's.

[waxxonMTL]

i thought you were in love with CW and now out of a sudden, we see you with a 1500$ tune haha ! Considering you already have the pulley, did you simply paid 1100$ + 150$cable or you had to pay 1600 for the stg 2 files ?

What I heard most about the unitronic is (1) they mess up a lot with the transient throttle response (2) no TCU files ( and no eta as to when it will be available). have you noticed (1) ? and heard about an upcoming eta for dsg ?

Maybe the fact that he has constantly said he like testing things and he wanted to push the CW as far as he could, and he was not affiliated with them will finally be understood. Great runs Mike, hope to make it out next week to get those logs done and see that that 60' in person. :)

Yeah, I just like testing things out. I have a 12 year history of doing that on audizine, longer back on audiworld. It's fun for me. The CW was great. Not sure I was "in love" with it, lol, but I was and am impressed with the power, the removability/stealth, and the value. You really cant beat it. Heck, i'm putting down the same trap speeds with a $1500 tune (a tune that datalogs very well by the way) as I was with CW. The downsides are that it is not as refined when it comes to part throttle sensitivity. I may end up running CW on top of my tune when I get dual pulleys. I'll let you all know how that testing goes.

I've been driving the Unitronic more today and I can say the modulation is pretty decent for my taste. I'm a person who really doesnt like devices like the Sprint Booster as I do tend to like more linear throttles and this Unitronic program isnt bothering me at all. Boro92 didnt like his program (which may be different than mine) and I trust his assessment of throttle sensitivity probably more than my own, lol, but no issues on my end.

Thanks Sean! Yeah that was a wicked 60ft. It seemed like a fluke that it revved to 4000rpm since I have stock LC but I must have hit it just right on the upswing that it took off past 3000rpm. It felt very nice, lol.

thanks for sharing mike !

[DGVR6]

From what I can see they just bleed boost on the less aggressive map (no intercooler).
With e85 mix I've seen timing go into the low to mid 20's

I have the 100 oct map.. I can try to pulls some logs and shoot em over ;)

[Hawkpilot6060]

Nice run Mike! 11.9 is a great run, kind of wish I had gone out. Conditions looked great, but I had a long work week. Oh well, keep us posted! Rick

Rick I completely understand. Believe me I thought about ribbing you a bit trying to get you to come out and then I started literally falling alseep in my car waiting for the second run, lol. I was out of there an hour after arriving. We'll get you those 11s this coming month :)

Mike

[TexasDfwS4]

I still can't believe that even without th TCU tune you cen get an 11.9 WOW

[HeymyAudi]

Good to see my boys back home putting down good numbers

[blazeblunts4]

whoa, mike, unexpected. I am proud of you. Made the switch.

[jsh139]

Nice runs. I'm a little surprised that you would go with Uni, given that (unless I read it wrong in their thread) their revert to stock isn't a true revert. I.e., it doesn't put back the original flash file that was on there before you put the tune on (like EPL does). Please someone correct me if I am wrong.

thanks. yeah that must have been a misunderstanding. Uniconnect+ not only puts on the correct OEM stock file for your box code but it also makes certain it was the correct revision of your OEM file (which is necessary to pass a spec/actual scan for TD1). Its completely automated as well so no mistakes are made. No need to wait for someone to be back from vacation or not busy with other responsibilities/customers :)

That is certainly the biggest negative of the other flash at home product.

[bhvrdr]

That is certainly the biggest negative of the other flash at home product.

It was a big deciding point for me. Flash at home was about convenience. Its not convenient to me if I have to wait for days or weeks for a tuner to load up my program on their server before I can flash from home. Thats actually much less convenient then me just driving an hour to a local XYX or ABCD tuner/distributor and having them flash my car that day. I like the Unitronic interface alot. Its very polished.

Some may recall a while ago I had an independent shop damage my car to the point it was immobilized and I had to have my car towed to the dealership. It was very nice having the CW because I just disconnected and removed it in the parking lot and it was a done deal. Unitronic should be that convenient as well if I were to want to flash it back to stock or even to a 100 octane or the summer performance program at will.


EDIT:

I had to do a bit of a road trip yesterday and decided to test out the car with the transmission in D mode as this is where I got most of my mild part throttle jerkiness with CW (I almost never ever drive my car with the transmission in D mode...only long distance highway road trips). It is butter smooth with the Unitronic. So far I havent been able to invoke any odd throttle response behavior at all and i've been working at it.


Mike

[scottycs]

I am guessing this is a shot at Tony at EPL. Tony loads the correct OEM file in the server after verifying your stock file during that setup. From that point on, you always have access to flash the car as you see fit.

How is the UNI DSG Flash?

i wouldn't even bother arguing .. its deeper than what meets the eye here.. i've already told mike that i went in for service with my EPL flashed back to stock and he told me i must not have got scanned.. i looked at my paper work and it said my car was scanned for codes.. but i guess i got lucky as i was told.. I knew sooner or later there was going to be some negative EPL misinformation in this thread.. but its Mike's thread he is free to post what he wants in it.. misinformation or not
