Help with tuning for E85

[SUPERTRUCKER]

I am looking into tuning my forced induction truck to run E85. Just wanted to know what I need to do to change my tune for it. I am new to the tuning world. Thanks Thomas

One way is to set the AFR Stoichiometric table to ~9.8 (E85) vs 14.68 or thereabouts.

Or look for a similar operating system for your PCM that has Flex Fuel and look at how it is set up, and/or maybe you can use the FF OS in yours. (though compatibility is another thing.........).

i took my 93 octane tune....added 30% to the ve table and 35% to the boosted ve table and then dialed it in from there. I tuned for the exact same a/f as 93 octane at part throttle and 11.0 afr at WOT. I didnt change anything with my wideband....just whats listed above
