Thread: wtfbbq is my car doing?

so at the track last night, i got in 5 runs...the first three were all within about a half an hour..



my car is literally getting stuck at 95mph...every time id get to 95 it would just stop pulling (its around 4k rpms), almost like it was hitting a rev limiter. the worst part is i still have a few hundred feet of track when this happens.

two of the e/t's are exactly the same down to 1/1000 of a second. something weird is going on. the only thing i had going for me was it was consistant all night.

then my last two runs the same thing happened again...it was a little bit colder this time around.



and this isnt to mention that my trims were locking at 0 and i had .5* of KR last week and now this week (without changing the tune at all) i have up to 3-4, and up to 6* of kr and my trims are locking a 3.9
i logged my last run, but its on a friends laptop. i'll get the scan, look it over and post it asap.

between the crappy track prep, my magically appearing kr and fuel trims at 3.9, and the fact i cant go faster than 95 is holding me back from 13's.
what is going on?

ill take that as a no?

I'm still waiting on the scan. Could be your tune has a high speed limiter programmed wrong or something. Hard to say.

yeah, the fuel trims are deinately causing knock. they were locking at zero 2 days before going to the track..

im waiting on the scan too..

yeah i think thats a big part of the problem. we did 3 maf tunes after doing a ve tune, but it was like 75 and beautiful out, at the track it was 40..

still doesnt explain the not being able to go faster than 95mph part though...

on the way to the track i took it up to 102 from a 30mph roll..it only does it from a dig..
