I'm in the same boat... Only mine's a N341!!! I've got a '87 Turbo Convertible from Japan I believe. Looks to be an S4...
N318 ECU's are plentiful in Australia so possibly just a standard Aus Spec S4 Turbo Coupe? There were a couple of different things with Aus spec models... Can't remember them though!

The resistor pack is all upstream of that.

Okey sorry I ment by saying low impedence. That it was the early T2's
hence being low impedence. But your right the impedence doesnt go into account in the ecu.

I used to have a chart, but that got lost.
Anyone with a HyperRev or RX-7 Magazine for the model chart in the back?

I think they are all Japan imports?
Therefore, all those models and ECU's are all Japan-spec units...

I putting a Rtek 1.7 chip in the "new" ECU and then swap into the Rex. Thanks.
I think the N332 ROM versus the N333 ROM is different - try contact the RTEK guys for confirmation.
I know we were having problems swapping modded EPROMs from N333 to N332 - it just didn't work - years ago.
