I have compared this tune I have on PCM with others and the injector scaling seems to be off.
N* Throttle body
LQ4 MAF
42.5lb Injectors Bosch Greens
XP Hot Cam
I am hitting 180kpa but my injector duty max is 45% @ 22lb/min MAF which does not seem right. The car does not perform when on boost, stutters and will not rev. tops out at 9.5 KR. :mad:
MAF settings were wrong. Tune now is better but still need tweaking.
I have log if people are intrested in looking to help out. No wideband yet, gets delivered in a week.
I am getting 10deg knock at part throttle. I have an xp cam with 140 springs. Could this be false knock??
Zero the AFR Spark table. Plus you have added 9* timing in the 1800 & 2000 rpm light load cells. That's way too much timing. And don't go WOT until you get the wideband on.

Thanks russ, this tune is actually a zzp can tune for my mods. Its utter garbage and all over the place. Looks like I am starting again. Its running lean and has loads of kr. Trims are running at +15.
I dont know how they can sell these tunes like this.
I've retuned a GTP that had a ZZP tune. It wasn't even close.

Done some tuning today and took out a lot of spark and added 20% fuel. Safe to drive till my wideband gets delivered. Will keep you posted.
