TPS on DJet with 2056, Idle circuit Options

[thomasotten]

I have a 2056 cc engine running D-Jet. All new lines, harness, everything. The engine has 96 mm pistons and larger valves - 44/36. I had to tune the MPS away from the original factory settings or it was just running too lean. So I richened it up and it runs really well now, checked MPS and adjusted with an AFR gauge. Only worry is my ECU mixture knob has no effect. The throttle position sensor has been rebuilt and calibrated with a new board. I double checked and triple checked the calibration because I know that it won't go into the idle circuit, where the mixture knob has authority if the TPS isn't calibrated correctly. So, the next thing I tried was changing out the ECU. Still acts the same. Idle mixture knob has no authority. So I am wondering, is there something about adjusting the MPS that will cause the computer to never use the idle logic? I know it doesn't have any feedback that you get from an O2 sensor, but I am wondering if signals from the MPS can keep it from going into idle mode.

Thanks

what is the problem you are addressing?
Too high an idle?
Have you smoked your engine to eliminate air leaks that would defeat idle adjustments?
