Attention E85 Users and Injector Dynamic Injectors

the car will not run very well on full 93 on an e85 tune, you could probably get away with 30-50% max. I've run all 93 on a 50/50 tune without issue.
Car will run way lean with ethanol in the tank on a pump gas tune (substantially different stoichs) but the computer will be able to compensate for some variation. I think beef is right--no more than 30% E85 mixed in with pump gas and you should be ok on a pump gas tune.

What about the other way around? 93 on an e85 tune? I know it will run like crap but would it be decent enough to let the car idle and clean everything out? I doubt my tuner has time to give me a 93 tune when he hasn't even given me a tune update yet so it's not really possible to get a 93 tune.
If you just want to idle to get some 93 circulating through it just use your stock factory tune.
Personally I would find a new tuner if yours won't even give you an update. You really need a 93 tune in case you want to take the car out of town or if a bad batch of E85 gets distributed in your local area.
Aright, another question: Would the stock tune be ok with idling if I have ID1k's and a return-style fuel system?
+1
Not without updated injector information in the tune.
I believe it's the other way around, on a 93 tune, the car will typically run leaner on the e85, you need 30-35% more volume for e85 than you do for 93
again, about 30-50% max 93 that way.
Ya, monday morning brainfart. I was explaining it backwards.
Stoich for E85 is substantially lower than pump gas so e85 will make the car lean out if tuned for 93 octane. The reverse is true if someone has an E85 car and they put in 93 octane. The stoich for e85 is so much lower that the computer will flood the car with fuel thinking it's running lean.
Thanks for the sanity check beef :beer: I edited my first post so there's no confusion.

Not a super high quality video here but it gives you the idea on how we set up to do our ID2000s

Good info/advice. This needs to be a sticky.
No. The IDs have different injector dead times, not to mention they are 3 times bigger the CC lol
Yeah if you have a e85 tune and throw 93 in it, the car will run fatter.
Nice little video ya got durrr lmao
Thank god the winters here in FL are a joke and we can drive our cars all year around lol
No kidding, I can drive my car around here on E85 all year round. Only gets about 25-30 on the coldest mornings and no snow here ever.
