Hi guys so I've just got a question about the trigger setup on my MY00 EM1 VTiR (Australian model - B16A2) , mods please move this if it's in the wrong section.

The trigger wheel; I know it's a 24 and 1 wheel but my questions are
1. What type of sensor is on it? Hall effect? Reluctor?
2. How many sensors does it have?
3. Does it have a missing tooth? Base angle BTDC?
4. If it has a missing tooth where is it?

Thanks in advance, trying to get the car running on an aftermarket ECU. Couldn't get the info I needed after searching for a while.

 

You actually have THREE sensors inside the distributor housing and all are magnetic pick-up pulse type.

TDC = 4 pulses per revolution
CKP = 24 pulses per revolution
CYP = 1 pulse per revolution

 

I'm just trying to setup the car on an aftermarket ECU, the car is now OBD2 with a patch harness to OBD1 and then into an ECU so that's why I'm hunting the info

​​​​​Does that change what sensors are used? The wiring diagrams for the Haltech ECU I'm looking at only uses two sensors, not sure which it's using or if all three must be used etc

 

I'm trying to setup an aftermarket ECU for the car, the haltech base map I'm looking at uses wiring to only pick up two of the sensors, does the fact that it's an OBD1 converted to OBD2 change anything in that regard?

 

No, OBD-1 and OBD-2 distributors have the same three sensors and wheel tooth counts. The OBD-2 system also uses a 4th sensor at the crankshaft called the CKF (Crank Fluctuation Sensor) and compares it's signal output to the CKP sensor found in the distributor. It is NOT necessary for your Haltech system.
