overall fuel trim problem.

Post by burmese434 »

Built 2.0 gsr turbo w/ RC 1200cc injectors. I'm having trouble getting the a/f fixed. It seems like the injectors dead times are way to high but I put in what rc told me. I tried using my lsvtec 1200cc tune and changing the dead times and still don't seem right.

So I tired a new map and putting in the injector size,map sensor,dead times. I have to put in like -50% overall fuel time to get the a/f 14.7-15.0? I've tuned other cars and never had that much overall fuel trim.

lmk what you guys think

10.0 11.0 12.0 13.0 14.0 15.0
2.55 2.28 2.00 1.76 1.62 1.46

The dead times provided by RC are more than likely incorrect. Try much lower dead times and see if that helps.
