12.8 @ 109 Stage 2...

[importraceram]

Just got home from the track. Had lots of fun but also had some less than desirable numbers. As of yesterday my car was flashed EPL stage 2 with CTS intake.

Drove 45 minutes to the track, checked in, went right to the line with minimal time to cool down... [email protected]. Get the slip, I'm thinking ok my car just needs time to cool down. Pop the hood and let it sit.

Fast forward two hours, car has definitely cooled down a bit and temps are dropping. I'm ready for a good run... [email protected]. Both runs had 1.9 60ft time which is likely part of the issue.

I had a bit more fuel than I probably should have (between 1/4 and 1/2 tank) but that probably wasn't a huge factor. Also I have very minimal drag racing experience. Both runs we're done using launch control which held me around the stock 3200rpm and ,to my knowledge, I didn't have any wheel spin. Another thing to keep in mind is this was the 3/30 TCU file. I didn't find out I had 4/28 until 5 minutes before I had to leave. Maybe the newer file would have helped and possibly launch higher? I could be wrong but I'm pretty sure the car, in "S", shifted before 7100rpm on gears 2+. But yet in manual I am able to achieve 7100rpm on gears 2+. Another possible part of the problem.

All numbers aside, I am very happy with how strong the car feels but yet it's only 2 tenths quicker than stock? I'm excited to hear some feedback, diagnose the issue, and get back on the track!

Edit: I myself didn't actually flash the car. The owner of the shop that I take my car to did after he put the pulley on. I walked him through it on the phone and specifically said "click the stage 2 file". Could he have possibly fat fingered it and pressed stage 1?

That 60' is not that great if you were using LC? With nothing ore than a CW piggyback I was getting high 1.7's and running 12.6x@108 (high 108's at that ). Do you know what the DA was? It can make a ton of difference in how the car performs. Your times are certainly in line with Stage 1 tuning, stage 2 should be performing significantly better.

[cjw]

My car short shifts on launch control, I wonder if yours is doing that too? Waiting for a fix from EPL.

Still I'd expect more mph. Your conditions look solid.

[deadpool7777]

It took a few days for me to actually feel the full potential of my stage 2 from EPL.

[chet.rowles]

Yeah...something might be up. I just got back from the track too...did 109.5mph and a 13.0, on stage 1, but DA was an awful 2750.

What were your IAT's? I know you said you cooled down the engine, but from my logging, having the car sit with the engine off does not help lower IAT'S with a stock cooling system (actually increases it) FWIW.

Your D/A's are enough for a low 12's in a strong file on 93 octane stg2, and a 3,200 rpm launch control isn't enough to spin (you may benefit from a 4000-4500rpm LC actually to lower 60ft times, and therefore lower your 1/4mile and overall trap)

In comparison, I ran [email protected] with an older EPL stage 1 in similar D/A's when I had mine with a OEM tcu.

DA is listed as effective altitude on the slips I believe. Conditions were certainly not terrible especially the second run.

Unfortunately I had no way of measuring IAT's so that I cannot tell you. Like you said, on a revised TCU tune w/ a higher launch, the 60ft should come down to where it needs to be.

[BlownOne]

Something is way off here...my stage1 91 octane car went 12.31@ 111mph. Even assuming he accidentally loaded a stage1 file, you should be faster. I would contact tony and he will help you out.

what were DA'S with that run?

I posted in the 1/4 thread, but around +350 da iirc.

[Whitee]

Probably short shifting with launch control which is causing a terrible 60 and overall bad time.

Thanks for the responses guys. Yes I will double check to make sure stage two tune is installed and I will check with tony regarding updated TCU tune. Can't wait to get back out there! Any other ideas?

Flashed stock file lol?

You're in NH? Epping is notorious for bad times...

Nice. We won't see da's like that here in Texas until late fall. If ever. Gives me hope tho. Car ran 13.0 last night at 109.5 on stage 1. Would think that puts me at least half second quicker in decent air.

Yes ran at New England Dragway.

How does a track affect MPH though when conditions are good? a 1.9 60' is one thing, but a 108 trap seems slow too.

I'd expect a 93 octane, Stage 2 with TCU to be 115+.

[hotleadsingergu]

Ya that's not great...stock for the B8.5s is listed as 12.9 quarter. There's no chance you should be running 1/10 faster with a stage 2, unless the DA is horrible and your tires aren't keeping contact.

[DGVR6]

It's power related.. Either something is triggering to dail back power or it's not there.
The back end of the track you're losing 1 tenth.
Look at your 1000 and then your et. Conditions are ok, you can also be heat soaked, but something is pulling power.

[bhvrdr]

Its a track at sea level in a decent DA so yeah, the trap speed looks a little less than what you'd like. A better launch would help the ET. The best thing for any of us looking to make decent times is to log the car to see how its doing. Ultimately, there are just as many stage 2 cars that run mid to high 12s as there are that run low 12s to high 11s. The environmental conditions (yours werent bad) and the condition of the car can make a huge difference in power. Log, log, log.

Track prep will not have any impact on mph and 60' only effects et.

[cjw]

That's my point. Saying it's a slow track really doesn't mean anything if the weather was favourable.

[importraceram]

Yeah seems like bottom line is the car is just not producing power...

[roadawg]

Put 5 gallons of E85 and I'd bet money you would gain 3 + MPH.

If its not fuel related, something else is off causing boost or timing to be pulled. Agreed on the logging, you are leaving a TON of power on the table.

[A4SlineWA]

I feel your pain. Im running a Solomotorsports tune from the previous owner and ran a best 12.7 @108 on my 2011 DSG S4. Stage 2/APR pulley. I wasn't too happy because my friend who went and didn't launch got a 13.2 @107, stock. I asked Solomotorsports for an updated tune and got a best 12.6@110. Not much difference. I was going to go with EPL but your numbers seem like mine.

I too felt that with the updated tune no TCU tune, using lunch control, I too noticed the car wouldn't shift all the way to redline on 2nd or 3rd gear.

Here is my thread. I created similar to yours. http://www.audizine.com/forum/showth...ighlight=Upset

[xpoweruk]

Seems like the car isn't making power

My 6MT revo 1+ did [email protected] MPH with a poor DA & damp UK air running E10 fuel

+1, hard to tell anything at this point without logging for sure as it tells you how the car was performing during that particular run.

I wouldn't shy away from EPL just because of my two runs Friday night. I have no doubt that this will get sorted out and I will be in the "normal" stage two range. Customer support/service has been tremendous as well so I have faith.

I don't think it's heat. I ran my car a couple weeks ago 12 passes down the track with groups of 4 runs each and all four were within 1 10th of one another. It's not the heat of summer here but I was still surprised she never seemed to be impacted.

[email protected]. Both runs had 1.9 60ft time which is likely part of the issue.

Definitely not he norm for a Stage 2 car.

I had a bit more fuel than I probably should have (between 1/4 and 1/2 tank) but that probably wasn't a huge factor. Also

I ran mine with a full tank of 93 only and tires at 41lbs and pulled 12.2's at 113-114mph. Best 60ft was 1.887 so that kept me in the 12's for sure. Did so just to see how she would run as I keep her every day on the street as a daily driver.

I have very minimal drag racing experience. Both runs we're done using launch control which held me around the stock 3200rpm and ,to my knowledge, I didn't have any wheel spin.

Definitely something up. I have APR's LC set for 3-4-5k launches and even 3k I spun just a bit. 4k I spun all over and ran a 12.6 with a 2.0 60ft. My best runs ever are without LC.

Torque on my car only measures airflow rate not temp. Couldn't find where to get that at.

I'd expect a 93 octane, Stage 2 with TCU to be 115+.

Yep. Best I ran last fall was 11.9 at 115mph at a different track than above with tires at 34lbs and 1/2 tank fuel.

SC Belt slipping maybe?

[chaos2984]

Sounds like these off brand tunes are not the way to go. Even APR and GAIC has issues but they weren't that bad from what i remember. I would be super pissed for paying all that money and getting 0 results. You should be in the 11's. I think when i get a tune I'm going to go with GAIC.

[ptper]

Couple of EPL guys ran really good times, so I wouldn't write them off yet. Solo, on the other hand...

[demonmk2]

on your torque app do you have the free bee app or did you buy it?
you should be able to look at the iat's on the raw data display or add a display just for that reading.

[BDP]

Yep. Best I ran last fall was 11.9 at 115mph at a different track than above with tires at 34lbs and 1/2 tank fuel.

Are you running at National Trail? Just curious...Kilkare is 20 minutes from my house so I usually go there. I've been trying to go and baseline but this Ohio weather...

I've always ran my fastest times at Edgewater down towards Cincinnati.

[fitzydude]

We recently did some logging on my EPL tune and saw that the car was not bleeding boost but it was being conservative on the timing. I'm going to get with Tony on Monday and see if he can add 5-6 degrees of timing to get my car running properly.

Comparing tunes, the EPL tune makes much more low/mid range torque than my Revo tune. But overall the car is a tad slower because it's not making as much power at high rpm. Hopefully adjusting the timing values will correct my problem and for reference my Revo tune went 12.6@112 with a crappy 60' and 93 octane. My EPL tune does not seem as quick even with an E85 mix 😠

I do both. We did trails on the 12.2 runs. Kilkare is where I ran 11.9. Never been to edgewater. If you ever go pm me. I'm always up for a trip. We could get a few of together even.

I'll pm you when our group charters out Kilkare. We do 3 or 4 events per year. 75 or so cars and we rent the entire track for us. Costs vary but you'll get 25 runs in if you want.

[hodrosS42001]

Do you have a boost gauge? Was it boosting properly or bleeding boost? Something isn't right.. No offense those runs were sh*t.. Are you sure you were on the Stage 2 tune and not stock for some reason?

[Tony@EPL]

Obviously somethings not correct here. This is basically the same file that we went 11.8 single pulley on pump gas with. Call in Monday.

I'm out of computer/cell range the rest of the day or I'd try to get with you today.
