I recently switched over from 93 to E85 and wanted to get a second opinion on my tune, under partial throttle from 1000-2300ish rpms its not running the smoothest. And at full boost I was getting 1.4 knock in the ecmlink datalog however I have yet to make a pull with the second pump installed. I based this tune off of a 110 octane tune my car had from boostin performance. How do the fuel and timing tables look in your guys opinions? do they need to have a more gradual change?
