trying to set up my initial PE tune for e85. Is commanding .80 lambda (7.82 afr ) a good starting point at 14lbs max boost? Cant find enough information that I would validate as good info.
I don't plan on changing my meth setup.

same as a gas scale in AFR in HPT... 1.280 should be fine to start with.

I run 1.27-1.275 on my flex fuel setup. Was at 1.278 prior to dialing in the tune saturday and settled on 1.275 and let the meth do the rest.

Then again this was 24+psi of boost on e60-62.

is the 1.27-1.275 the multiplier you use for PE?

I usually start around .78 and tune from there

Unreal

Yep. Then again my actual target AFR with meth I shoot for is 10.8-11.0.

0.78 lambda I hope, not eq ratio....

1.28 for those people reading who are going to put in a value in HPT

schpenxel

0.90 lambda should do nicely

Just kidding

Been doing more like 0.82 lambda on mine
