E85 on Stock tune?

[therod785]

Possible to run e85 on stick tune. Need to temporarily return to stock tune. But have half tank of e85.

Will it be safe ?

Yes you will be safe, it might run a little funny at first until the computer adapts to it. I highly recommend putting some 91 or 93 in as well. If it was me I would drive the car until the E85 is emptied then refill with 91 or 93 for the stock tune.

I'd fill the rest of your tank with 91 or 93

As said run it down as much as possible before swapping. Fill to the top with pump 91/93 and give the stock tune a happier mix.

I'd be out driving it very enthusiastically. Shouldn't take long to burn a half tank that way and more fun too!

Asking the pcm to trim out at 30% I dunno man.
