So after being on the dyno… I was able to get my ‘20 6.4 charger to gain 30 whp and wtq on e85. Commanding 23-27* of spark during wot. I initially had extreme trouble dialing in the fueling playing with Neural Network. So at the moment.. my power enrichment table looks god aweful. Some cells have PE at .0050 and the very next cell is .0120.. I took it off the dyno still a little rich.
What is the safe Max power Lambda value for PE on e85? That is what I struggled with the most. Going back in 01/28/23 just to dial in fuel.
So I do have some follow up questions:
What is max power stoich for E85 that is safe?
Should I start commanding 27* spark during WOT earlier? Or is a ramp up from 22* that phases out to 27* more ideal?
