Hi Danno,
The Sub-throttle Actuator, I guess it is a stepper motor, i saw it have 4 wires- maybe 02 coils. It also have separated position sensor connected to PIN#19 Stock ECU
not map to TPS Position... so I gave up about Megasquirt (Idle Air Control function) to control this output.
For next step, I will keep stock ECU parrallel with Magequirt but cut out the output of Stock ECU at:
- Injectors
- Ignition outputs
Let me see what will happen
