Can you log individual cylinder timing? This is a real useful tool for your kind of project.

I need to flash the DME to log individual cylinders. I could do this if I got a cobb... maybe I should do it. How could there be an imbalance if I am injecting pre-turbo into both turbos? Even if there was imbalance, I have more than enough E85 in the fuel itself to cover the boost targets I am testing at. It could be the DME reducing timing for some kind of torque reduction (according to the tuner), but I don't think that it. Weird.
The STFT are on the graphs as "Trims". They are almost maxed out since I run a lot of E85 with no flash.
