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.

your wideband is showing too lean 13.6 @ wot is way too lean......
 
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.

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

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.

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

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

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

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