I am strongly considering a Megasquirt system. and need a few questions answered in order to figure what system will work for me. so here goes..


1. where is the crank angle sensor (CAS) or crankshaft position sensor wheel and what type is it (Optical/LED Sensor? Hall Sensor? VR Sensor? mag sensor?)

2. How many teeth/windows/slots and what orientation does the CAS or crank trigger have? (any missing? all evenly spaced?)

3. Do these engines have a fast idle valve or IAC? If so, how many wires are connected to it? Do you know if it is an on/off, pulse width modulated, thermal, or stepper type?


Thanks

1. There are TWO camshaft position sensors on the 1JZ and 2JZ. There a magnetic type of sensor. Megasquirt n spark IIRC is the only software that can utilize the dual wheel setup.

2. One wheel has 24 evenly spaced teeth, the other has 1.

3. These engines have a IAC. It has 6 wires, and is a stepper motor design, however it can be re-wired down to 4 wire stepper.
