Attempting to get this wot dialed in since making changes on the car. It is lean up top , is this a case of Maf histo copy and paste and multiply by half %? Correct me if I?m wrong but everywhere else looks good with fueling. I am here to learn as my previous cars have been tuned by others but have made some changes on boost etc got tired of waiting all the time. Appreciate any feedback . Tune and log below

In my opinion, running in the 12's on E85 isn't that lean at all. Running 11lbs of boost isn't a ton compared to what others run.
I'd be commanding around 12's in the alcohol table but that's just me.
But if it's lean up top, you don't really need to overthink it. Just smack it with 10% more fuel to bring the fueling in richer. See what it's like and smooth the table. Would take forever to do a bunch of logs to slowly creep up on it when one or two flashes could get you there sometimes.
Appreciate that. Yeah i know. Just would like to keep richer for peace of mind but for sure. Hit the mad table at 10%? Whole table or just where it starts to lean out ?
Just where it starts to lean out.
You got some pretty wild pressure swings on this.. it might add up to hesitations between shifts. I saw 96 psi to 32 psi of fuel pressure on one shift. This is going to be coming from your AUX fuel pump.Quote:
