I thought it would be a good idea to create a new thread, since my other one (start problems) is resolved. I'm having a serious fuel setting issue, I've tried the injbatteryadj setting, isn't helping; When I set it to correct specs, my combinedFT in closed loop is 29% to idle correctly. I also tried adjusting global deadtime instead, which seemed to help much more but still doesn't get it right. My ISC Position will constantly change with the fuel settings so I can't get it to stay at 30 with adjusting others.

It just seems like whatever I do, I'm not getting enough fuel.

Mod list:

-Walbro 255, Aeromotive FPR 43.5psi
-97 2G with 6 bolt swap
-95 EPROM DSMLink v3 full
-20G ebay turbo (12psi)
-RC 750CC injectors
-Dejon tool short route FMIC kit
-3" Punishment racing downpipe, 3" greddy ti-c full exhaust
-GM IAT & OMNI 4 bar map sensor


Whatever I can do to help someone help me, please let me know. I feel like the car is doing great and getting somewhere but I just can't get a setting right, but I need to find it. Please look at logs thanks!

Without looking at your logs (sorry my iPhone doesn't support ECMLink lot files, yet) you need to tune one thing, then the other. Tune AirflowPerRev first, get it to 0.25 using the SD VE table, then bring in CombinedFT's using injector deadtimes. That's it...

Once these are good then you can worry about ISCPosition and the LearnedIdleAdjust.
