It’s optimized right now for the 93 octane E10 we get here in NY. I made sure to fill up just as I was leaving NY so I didn’t use the gas in CT which would’ve produced SLIGHTLY higher numbers due to no ethanol at most stations.

Right now I also mixed in about four gallons of 112 octane as well. Tony’s in the process of designing a program to switch between pump gas and race gas maps for the ECU via laptop.
