82fxx board on 83f04 ECU

[streetbike]

Hello all ! I have a 82f06 board in stock and one friend have a UK S14a with 83f04 ECU

can I use it ? on what I find 83fxx ECU are australian !! How can this be possible ?

I'd guess that it should work. Yes, 83Fxx series are used on ADM vehicles. Maybe they're used elsewhere too?

The thing to watch will be NATS. ADM S14a's do not have NATS. Only the S15 got NATS here.

What you may find is that Nissan moved some of the pins so that you can't plug a non-NATS ECU into a car that had NATS. They did this with JDM (non-NATS) vs ADM (NATS) S15's. They swapped the fuel pump relay pins (ADM = pin 104, JDM = pin 106). They also swapped the CAS 180/1 degree signals (swapped pins 30 & 31).

Given that S14a ECU is very closely related to S15 ECU I wouldn't be surprised if they did the same with euro S14a. The fuel pump wire is easiest to check - if it's on pin 104 then I'd bet that they've swapped teh CAS pins too.

I have double checked the ecu number on my mates car . and He made a mistake .. his ecu is 82fxx .. so there is no problem !!
