Hey guys, i obviously have no idea what i'm doing, please see the attached log.
So my I just built a 6 bolt and dropped it in, it ran great on 93, put simple base tune in that was based on my SD tune prior to the build and it ran fine. THEN I put e85 in the tank and I realized that i have no idea what i'm doing.
The car sounds likes it missing at idle and my wideband stays lean. When i drive the car the AFR is all messed up, i don't need a wideband to tell me that it just doesn't run. When i try to step on the peddle it stays leaner than it should be.
I followed a few threads by trying to adjust battery table, no values stop it from going lean. Setting dead time at 700 won't stop it from being lean or make the car drive well.
I tried to adjust to SD/VE idle sells but i have to drop them all the way to the 20's to get airflow per rev around .25, this just seems wrong.
I'm not sure if there is a mechanical issues that just cropped up when i put e85 in the tank or something else i going on. Any Thoughts?
Fuel pressure is 43.5
No boost leaks
Fuel pump is Aeromotive 340 that i have ran for a few years with no issues
FIC 2150's
