Guidance to lean the mixture from 5000rpm to 6500
Running e85 gt35r ball bearing and dual 450 walbros. Need assistance with what I have to due to slightly lean the mixture in that rpm band I’d like to see 11.8 to 12.5 afr on e 85 but I’m right around 11.0 afr and breaks up at that spot! |
Ensure you don't have a boost leak.

Positive |
It’s not a Leann burp it’s a hiccup from over fueling e85 tends to break up a lot under 11.3:1 afr |
This sounds like all you need is to increment the fuel map cells using ecu flash. Have you tried pulling fuel out of your fuel map between 5000rpm to 6500rpm over all loads above 100? Capture an evoscan datalog first and you can really zone in on which load cells it starts to dump in fuel.
Also, you have a pretty narly fuel setup. Are you on aftermarket FPR? |
Yes aeromotive |
