I also need to check the calibration of the sensor. I have chased data before to find out it is a sensor.

The learning curve on the fuel system on the E-85 has been a little rough but the results on track look very good so I’m sticking with it.

On the positive side the C&R cooling stack look like they work well and the bigger intercooler bricks are also keeping the inlet air temps down.

I really am enjoying getting some knowledge dropped on me before I start my own journey with learning E-85 and the fueling requirements of a big power plant.

Hard to see from the logs on the screen. Was the pressure dropping the entire time during the pull or did it start to catch back up (possible issues of pump reaction being a dead head setup vs a return style fuel setup)?

You said you are using E-85 from the pump correct? Your system using a GM computer so have a flex fuel sensor installed to help the tune correct for variance in the ethanol content? (believe i've seen as low as 70% from other boards on the ethanol content).
