E85 Stoich Chart

[Asteroid]

Does anyone have a chart of stoich for Ethanal content around 85%? I just tested my E85 and it checked out as E90. I would like to see a chart of stoich from 70% to 95% in increments of 5%.

What formula is used to calculate stoich based on ethanal content?

TIA

Pull a flex fuel tune from the repository and see the values GM uses for stoich vs. alcohol content. The ECU rounds it a bit anyway even if you use actual stoich numbers.

I don't have a copy of it here or I'd post it.

Thanks for the tip but I cannot display a .bin file on this desktop computer.
