Sensor differences between year? model?
 

i know the ECU is different between 86-88 and 89-92, and between turbo and n/a... but what about other components that the ECU utilizes? like the pressure sensor and the atmospheric pressure sensor and whatever else that connects to the harness that the ECU uses? are there differences in those? are they interchangable?

I think the S5 ECU has the atmospheric pressure sensor built in.

The other sensors would probably be the same between S4 & S5 respective to their method of induction. Oh, except the TPS. S5s are duals.

The only one that's prob. different between NA & T is the pressure/boost sensor.

The way I'd approach it to know for sure would be to go through each sensor's specs in the FSM.

Almost nothing is swappable between Zenki and Kouki models...

I know the Knock Sensor In the s5 Is built Into the ECU, rather than the external KS found on the s4 TII.
