What kind of timing are you seeing on e85 and say 26psi jet and gav?

I gave my mates El sohc 4l a tune the other night on the Dyno torque peaked around 12* at 26psi and 6500rpm made 445rwkw. Curios how much you see in a dohc motor to compare.

Well well well

There we go

Lean out 98 temps rise and see pre ignition lean out something that's already around ( lets just use 30% cooler because its an easy reference figure for e85 ) and u get ..... A desired lambda for E85 under big power

How much leaner u think ?

30% of a total ? Sounds ballpark yeh

Look here as a few quick finds

Each tuner has there own way

0.9 lambda is used by some others will go .85

See how small amounts can influence different outcomes, pressure is moved by large amounts on small tweaks

Your sheet should be up around 12.8-13.2
