We flashed the Pectel T2 ECUs on our two DP-08 MZR 2L cars with the fuel map built for MZR compliance to FRP F2000 (from Quicksilver). This, as part of our work to make the cars FC compliant. After the flash, one car (SN 004) idles high, but takes throttle well and seems to run smoothly. The other car (001) runs lean, backfires, hesitates on throttle and is prone to stalling. So, clearly we have some tuning to do.

So, it seems we need to adjust the fuel settings (TPS and whatever else needs calibrating).
I'm checking with Quicksilver to see if they can provide the proper fuel setting parameters, but because I'm not part of FRP, they owe me nothing. So, maybe if they are generous and I am lucky. Otherwise, does anyone know what fuel setting parameters I should use to tune the cars. I expect this would be either voltage or perhaps % of throttle open at idle and WOT? I clearly need advice...
