What are you targeting (AFR/E85)
 

Basically what the title says. I am just curious what everyone is trying to target on E85 in regard to AFR @ WOT. I know a lot of guys are in the 60-70% range right now but on average what are you trying to target. I personally add about 1 point of AFR across the board when measuring with a gasoline calibrated wideband. You can reference lamda too doesn't matter to me. Just want to see if what I try to target is in line with the consensus here on this platform.

On the OFT logged AFR you want lower 12s

I found it did not make much difference power wise so long as your in the 12's gasoline scale. I saw no change in power from 12.4 up to 13. I shoot for 12.5 - 12.8.

Get your afr flat, tune timing for mbt, change afr tune for mbt again and see if it changes power..... You really need to be on a dyno to tune E85, you can easily go past MBT before it knocks.

Ohh, and this is NA... Have not done a boosted corn tune yet.

My e85 tune runs high 11s at WOT.

Though it may not have much impact in power, it will have an impact on response. Every little bit counts, when you are trying to extract every last lbit out of a tune, track or not.

Is lambda=0.86 best for E100?

Depends on the vehicle, applications (FI of NA), and so much more.

for NA and for average of stock cars?

Same here - high 11's - low 12's

tuners use lambda for E85 and anther type of fuel
