2000 Engine swap into 1995, Trigger wheel, Boss Pulley, Crankshaft Pulley confusion!
Facts:
My car is a USDM MY95 (not sure if 95 or 95.5???)
The engine is from a 2000
The harmonic balancer I will be using is a Fluidampr 521001
The issue:
I am putting my BP4W that I am swapping back together, and I have come to the part where I need to assemble my timing gear. My plan is to swap the camshaft angle sensor from my 95 engine. I have an MS3 but I need to retain stock ECU functionality for smog purposes.
I don't have my car in front of me, so I am looking at the diagrams for a 95, it APPEARS that the 95 doesn't have any trigger wheel, which from what I read makes sense, the trigger wheel was added in 96 AFAIK along with OBD-II functionality.
It also appears that the 95 has a thicker boss pulley to make up for this lack of a trigger wheel. The 95 also appears to have some sort of plate that outside of the harmonic balance (11-408 - NO.1) on the diagram.
My question is, if I install all the 2000 gear under the fluidampr, will my engine run correctly on the stock ECU? It seems like it should, given that it has no Crankshaft Sensor (right?)
My next question is, could I added the 2000 crankshaft sensor, and run a 36-2 trigger wheel to my engine, and just leave the sensor unplugged when I need to run the car on the OEM 95 ECU? Can the megasquirt utilize information from the magnetic CAS/CPS and the Crankshaft Sensor simultaneously?
My last question is, do I need the plate that goes over the harmonic balancer (11-408) for anything? I honestly don't get what it's doing out there...

Even my 97 doesn't use the CPS for running the car, it's only for emissions. OEM ECU and MS3 both use the (NA8) CAS for running the car and I've left it that way so I can swap back to OEM for yearly emissions, seems that'd be the easiest route.

Yeah, I did read that, that 96-97 cars only used the trigger wheel for knock detection. I guess my main concern is that if I use the 99-00 stuff (assuming there is any benefit..), if that will somehow upset the stock ECU, but it seems like if my 95 doesn't have a Crankshaft Position Sensor, how could it???
