Default Converting 2002 engine to a 2003 engine - ECU

I have recently replaced my Chrysler PT cruiser with a japan import motor , my vehicle is a 2002 Chrysler pt cruiser with a 2L engine and automatic transmission.
The engine I replaced is from a 2003 model and it seems like the ECU doesn't want to correspond with the new motor. The only difference between my old engine and the new one is that the crank sensor is in the front not the rear like my old motor.

I have already tried going to my local chrylser dealer but they are unwilling to help here as they claim not to have the equipment to reprogramme the ecu.

Any advise would be greatly appreciated

2003 and up 2.4 (the 2.0 DOHC stopped production here in 1999) use 'NGC'- That includes a different trigger wheel for crank sensor.

I don't know that anyone can change ECU to fire the other engine.

Yes that is the same here. The 03 computer and wiring is the only idea that might work
