Mod list is updated. Base timing verified, mechanical timing verified, BLT all good. ISC has been tested, TPS is properly adjusted.
I recently upgraded fuel pump to a walbro 350, added AFPR set at 38psi base, bigger turbo, and 2150cc injectors. I am getting horrible idle surge, it seems once I go into closed loop mode. I must add AEM wideband on link is a bit off, in reality its a bit richer. Can someone look at my tune i am willing to pay.
I am running e85, all i need is an idle tune I want to get rid of idle surge.
I've provided a cold start log and another log after messing with fastidleisc settings
I must add, I have global set up that way because it runs really rich when starting, I have been able to get idle surge to STOP when lowering base fuel pressure to under 20psi or so but that doesn't seem right
