Usually the transition between closed loop and open loop is made by the trottle angle or position of the acceleration pedal, around 80-85% trottle, so if you can acces to the ECU parameters, you can modify this parameter and fix it at for example 25% in order to have a good Idle.do not forget to adjust the fuel and ignition tables to avoid discontinuitis in the transition point.RegardsFrancisco RE:
