The only reason that i even got curious about this is, know that some of the newer integras have Knock sensors in them, although my motor doesnt, my ECU may be looking for it due to the fact that i've changed everything over to obd1 (dizzy, ecu, engine harness, ect.). I'd really like to know if the ECU requires it in it's lil self check before it allows the motor to start, because if it doesn't then technicly it wouldn't need it! At that point i jest need to know if not having it will hold it back from running properly.

 

What ECU will you be running?

 

i can't remember the number on it right now & i'm at work for another hour or so.. so i can't really look at it till i get home.. but i kno that it's from a 94-95 integra non-gsr

 

You will not need the knock sensor if you're running an ECU from a motor that did not have a knock sensor. It's all about the ECU... if it is looking for it, you need it.

 

Is there a chart somewhere that will show me ECU numbers in comparison with wether or not they have / require a knock sensor?

 

the only OBD1 ECU's I know of that have knock sensors are the P13(prelude), P30(92-5 DelSol), P54(EDM Accord), P61(92-93 GSR), and P72(94-95 GSR).

P74 & P75 were the non-GSR ECUs. no knock sensor in those.

BTW if the ECU needs one, the car will start and run. But the CEL will be on. Code 23

 

:bowdown: Thank you very much for this info! :yay:

 

no problem. glad it helped.

 

no knock sensor on my b18b
