I ran my car for the first time ever on the strip yesterday at FIXXFEST. For those of you that don't know, it is a German car event held every year in Bradenton, FL. It is about 90% VW amd Audi but there are a good number of BMW's that show every year.

I ran 5 times with my best time being my first. The slip looked like this:

R/T: .635
60': 2.242
330: 5.657
1/8: 8.398
MPH: 91.62
1000: 10.745
1/4: 12.708
MPH: 114.51

My highest trap of the day was my last run at 115.06. I was very pleased with the consistency of the Cobb tune. 1/4 mile times ranged from 12.708 to 12.904 and traps ranged from 113.62 to 115.06.

Mods are DCI, ETS 5" FMIC, AR DP's, and Dinan axle back exhaust. Tune was Cobb race gas map running VPR MS109 on stock turbos and full weight on street tires.

I was supposed to get protuned by PTF this past week but they looked at my logs and said my LPFP needed replaced. After my first run, I got a 2A2D code which I found to be a low pressure fuel code. I will be replacing the LPFP and getting protuned by PTF over the next couple of weeks and hitting the strip again.

In all honesty, I expected to be in the low 12's but I obviously need to launch better to have a shot at that. I'm assuming the LPFP issue isn't helping times either.

Congrats! just need a better launch and you will be even happier! You can definately hit very low 12s with that trap speed.

with a 2.2 60' you will not see any good times no matter how good the tune/setup is, it should be your highest priority to get it into 1.9XXs
have you tried to play around with the tire pressure?

JStang - send me some logs if you want me to take a look. I'll be in Tampa from Dec 21 - 31

I sent my E30 OTS logs to dzenno last week. There were a lot of timing corrections which he blamed on my LPFP being on the way out. I decided to stay away from the E85 until I got my LPFP replaced which is why I ran race gas yesterday.

I just filled up on 93 yesterday and can log tomorrow if you want to take a look at them.

Would the LPFP effect times and trap speed?

I haven't touched tire pressure. What would you recommend I try for the next trip to the track?

On the front tires put the maximum recommended pressure should be 50-52psi

On the rears if you are getting horrible spin, try lowering the pressure by 3-4psi if still spinning bad, try lowering an additional 2-3psi.

once you get good traction your ET will improve but trap would suffer, then up the psi again by 1-2. You will have to play around with this back and forth, until you have good traction with the highest pressure = where the car hooks but trap is not impacted significantly.

do you still have your secondary cats ?

Depends on what you consider a good time. My buddy did a 12.1@118.50 with a terrible 2.192 60ft and he was happy with that.

I'm interested in getting a protune as well whenever you come down.

If your LPFP is struggling to keep up with demand your burn will not be as efficient and your fuel supply could be spotty creating hot temps, poor efficiency, and ultimately a hindered powerband.

great turn out at FIXXFEST this year! Gr8 times! are u 6mt or 6at?

That's gotta be a 6MT car looking at the 60 footer.

115 MPH isn't a bad trap, maybe 360 whp. Has this car been on a dyno and what tires(rear) are on the car. Regardless you need some stickier tires and/or a better prepped track, and you could yank some 12.50s out.

Car hasn't been on a dyno since mods were tune only. Tires are General G-Max. Probably not the most sticky tires but 1/4 mile wasn't in mind when I bought rubber. I am getting protuned by PTF and once I figure out the best way to launch I hope to crack low 12's.

Believe it or not, car is AT. I brake boost from about 2,500 in second and apparently went pedal to the metal from there. Need to modulate the throttle better. Maybe the linear map would help produce better launch.

Damn. That car is making a little better than 360 wheel at that point. Have any idea of what kind of boost you are leaving the line with?

I'd borrow, buy, steal, cheat some slicks/DRs and you should roll close to what you want to run. Honestly due to the nature of these cars, the torque spike makes it about impossible to find a sweet spot with all seasons even with a flatter curve. e85 will just induce wheel spin even more(more timing), however I'd imagine you'll pick up a couple few mph and to me that's the most important.

With his mod list, he should see around 12.3-12.4
No one should be happy being FBO and running a 12.7 when people get that with just a tune and racegas

I completely agree. I expected to show up and run low 12's. Definitely achievable if I can get the launch down. Not to mention protune coming soon!

I know he should be around low 12's, however I just wanted to state that if someone gets a 2.2 60ft, there is still a chance to get a decent ET just like my friend did.

Your friends car has been a huge inspiration to me FWIW and even though ive out ET'd him... im still chasing his trap thats a bad 135
