It comes out to be the same kinda but with more smiles per gallon

What kit did you decide on and how was the install?

Do it bro, you won't go back to 93.

I already a have OFT and run stage 2 so i got a delicious kit for OFT. Trying to figure out how to install it since their online instruction sucks and is for the ecuteck kit.

On my OFT non-flex e85 tune I’m hitting 34-35 degrees timing advance with local e85. I’d be surprised if MBT was beyond that, but your post is making me curious what flex fuel tunes are aiming for.

Not running E85/FF. it is almost nonexistent in my area. I have pulled up some V4 tunes and compared them to mine based of v2.7, the OTS E85 tune's timing tables are almost as mild as I am running on 91. There are a lot of other benefits to E85 besides octane, but if you have it why not run the timing to take full advantage.

I think mine is different

I believe the difference stems from the different calibration codes.. or possibly the file version (2. vs 4.)

Interesting, looks a bit closer to what I was expecting to see. Still seems a bit mild though.

Though a quick google search shows that Australian spec E85 is to be from between 70-85% ethanol. So tighter tolerance then here in the states.

Probably easier to look at a datalog for total timing (or ignition advance) since KCA will get added in.

For example, my car on the standard non-flex OFT 4.03 e85 tune runs about 34 degrees timing near redline.

I was curious if FF cars are pushing more than that. I’d be really surprised if they are because from what I understand that’s pretty much MBT, but a datalog from a FF car would be the easiest way to compare.

I didn't think of that, that is a good point.
