Hello everyone, I'm working on a dedicated e85 tune for my 2015 Mustang GT with the FRPP2 OS (I have the GT350 TB/Intake). If you haven't looked at the FRPP2 OS, many of the fields, including some of the Flex Fuel, are missing, so I am creating a dedicated e85 tune. It is never cold here, and I've tested 85% ethanol in late December, so it is extremely consistent. I have my AFR set right at 9.85.
I have changed the Cranking Fuel Mass to the numbers from the Flex Fuel table, which I got from the stock OS from the same car.
I have changed the Fuel Base Cold to the table from FFV Fuel Base Cold (Although the difference is extremely small at these temperatures)
I feel like the problem is my spark because it gets low in the two RPM dips shown here, but I'm not positive. Thanks for your thoughts
