Who's the best of the best E85 tuner?? I'm running a high Comp (14.8 to 1) Ls7 427ci with a pro systems 1170cfm Sv1 carb. It's time to start tune set up. Running a race spec E85 with 108+octane.
Can someone help with a starting point timing and lambda.
I'm thinking 26deg total with .74 lambda

I've always aimed for ~0.8 lambda on my e85 combo. Just be careful not too rich that you wash down the bores. I finished at 26 degs but i only have 11.9:1 comp. Maybe creap up on it from 20 degs. Only put enough in it to make power then stop
You'll find it will have a big window where its happy and also not ping.
