e85 tune issue

So I recently had my 2007 dyno tuned on 91 octane and e85. Car has a lethal return fuel system and id1300 injectors so I can run e85. Made great power on the dyno.... Made 775rwhp on 91 octane and much more on e85. The car ran great on the way home from the dyno.... I had to stop multiple time to refill gas and drop off a friend and the car started back up great. Come the next morning I go to start the car and it cranks abnormally long because it's on e85. I smell gas.... wich is bad.... look under the car and there is e85 dripping pretty good out of my header collectors. It flooded the entire engine and contaminated the oil big time. I originally thoughy i had and injector stuck open but through some diagnosis i determined the fuel system was working fine..... put the car back together and tried to crank it again and same thing.... ruined another $80 fill of oil. I then drained the tank and switched to 91 and loaded the 91 octane tune up..... car started right up and ran great so I determined I have an issue with my e85 tune.... but for shits and giggles I drained the gas tank and filled it with e85 while the car was still hot and switched to the e85 tune up and the car started right up and ran fine. So I was thinking it was a e85 tune cold start fuel enrichment issue. My tuner didn't really understand my reasoning for thinking there was something amiss with the tune and told me to try and cold start it again on e85.... and I ruined another tank of oil and flooded the motor out again in probably 3-4 cranks. Has anyone seen anything like this before? My tuner is very reputable in the business and has tuned 100's of cars just like mine, buy I think he has some kind of issue with the tune up on mine. Any insight would be appreciated. Thanks

E85 cold start needs work in tune. That 91 tune is all in.

Yeah that's what I figured. Tuner said he is using the same e85 startup tune as many other Shelbys like mine that startup and run fine. How much of a tune adjustment are we talking between the 91 and e85 tune you think? The car has a ported TVS, cams and a whipple elliptical monoblade so it made allot more than I expected

If the hot start is good, it should be close.

Have him go to Engine>Fuel>Open and Closed Loop>Cranking Fuel>Fuel Cranking vs ECT> set the 90*f and up rows to 1 and the row below 90* to .98

That should prevent spraying too much fuel while cranking in the summer and spray just enough extra to turn over when it's cold.

Cold starts with e85 are when you are most at risk of oil contamination, it will slip past the rings and get into the oil and he has cranking values set too low then it will spray too much fuel, get past the rings, and contaminate your fuel...

Think you need lund tune

So I think I have this exact issue. Did a tune solve it?

Tuner Sent me a revised tune and it started right up no problems. Although he told me originally there was no way his tune was the issue.... good luck
