    My GSX is currently running 93 octane fuel. I will soon be converting to e-85. But, what I want to make sure of is that my 93 tune is good before I go switching over to e-85. I want to have everything dialed in the way it should be before the conversion. I have attached a log from the car and all mods are up to date in profile. Any input is appreciated. I am still learning the whole tuning thing. Thanks for your input.

    You'll hopefully be throwing away your pump gas tune anyways when you switch to E85, so why does it matter?

    I wanted to make sure I had everything ironed out with pump before. Any things I need to look for.

    you need your pump done, because you are leaning out hard

    Your IDC pegs at 104%! A reccomended ~80% is the ballpark you should be aiming for.

    Yeah, I see. It's hard to keep them controlled when the boost just continually creeps the more you lay into it.

    I installed my FIC 1150 injectors today. Here is the first log of them at idle. I am going out to get a cruise log now. I am noticing that AFRest isn't matching with my wideband.

    Are you going to try running E85 on the stock fuel pump? Don't think so.

    No, I am not running e-85 on the stock fuel pump. I have a Denso 300 that I will be putting in. After just installing my new injectors, that is the only thing left to install before the coversion.

    Just seeing a 104 or higher IDC is proof enough that it doesn't mean much; how can you have more than 100% of something? Some even see much higher than 104.

    I've ran it on the stock pump AND the stock injectors. Yes the boost had to be pretty low.

    You'll be happy to have boost creep once you switch to E85. I wish I had boost creep instead of boost taper.
