What would be the most "correct" way to create an E85 basetune? I was planning on setting the actual/correct injector size, then setting a 30% overall fuel trim. Is good?
What about cranking/cold start/etc? Also need to set 30% ?
Thanks,
Mark
How would you begin an E85 Calibration?

You are close enough to get it started for tuning. I have done several (about 2 dozen) conversions and find that a tuned map on the same car will do fine with 23-25% fuel added in all the maps and 2-4 degrees of timing advance across the board to get it running well enough to get to the dyno. Pay extra attention to boost trims and light throttle, high vacuum cruise speeds. They need a bit of exra fuel to run smoothly.
