Also, you seem to be flowing 400+ g/s at about 21-22PSI or so... What turbo is that and what intake you have? I flow only 320-325g/s at this MAP. Are you sure your MAF cal is right?

Probably due to the E85 MAF calibration. We will expose the fuel density constants soon so that you can leave MAF scaled normal and run E85.

Watch out for injector DC issues with E85 and that much boost. You are probably right at the limit now.

You mean like a toggle for running E85 that will automatically scale everything?

Not exactly. There will be a constant that you can change to tell it the afr at stoich. Once that is set correctly, the MAF cal is normal.

Steve is correct, my MAF numbers are nonsense because of E85. It will be really nice to have a way to factor that out. I think I'm around something more like 300.

Steve you're right about the E85 maxing out my injectors too. Just today I went back down to a 50/50 mix to avoid that. I still have very low temps and no real knock so that will be the plan from here on.

Another log for you guys. Its definitely looking better than the last one. Just need to tune out that drop off and I'll be pretty happy :)

A lot better. Now I guess you can start tuning the advance timing.
