So my evo 8 almost left me stranded the other night lol.

Built motor
GSC S3 cams
64mm turbo
Radium FPR w/ double pumper
​​FIC2150
Speed density on E85

So I was just cruising home and the car started going full rich, 10.0 on the AFR, started bucking and falling on its face, finally couldnt keep up speed enough that I had to pull over and the car stalled. If i was able to get it started it would die without mashing the throttle. I was able to sit for a little bit and get the car driving normally for a mile until it did it again. Thankfully I was only 2 miles home so one more attempt and I was able to drive home normally.

Fast forward to today, I turn the car on and it's idling decent. Every once in a while AFRs will drop to the 11s and itll idle low but then come back. I'm trying to log the OMNI 4 bar I have but readings seem good. Keep in mind this is only at idle. I'm going to try to take it out tonight. What other parameters should I be logging? I noticed I'm only getting 0 at the crank sensor log and


the timing advance is very speratic?🤷🏼‍♂️

 

got a backup MAP sensor you can try? just learned theyre POSs

 

No but I'm ordering one anyways. If it isn't it now it'll be it later

 

Update: issue was 110% the omni 4 bar
