im 99% sure they are the same
the only one which had a slightly different map was the rb model ecu! that had to be different due to the gear ratios in the rb box

Aren't the JDM ones mapped for 98 octane fuel, and the UK ones for 95?
Or do the JDM cars just output more power because of the fuel, but run the same map as the EDM ones?

dont know trond tbh
i was talking to a tuner type fella though and he reckoned there was no difference in the map, they both are inclined to run rich at topend and think timing is set at 18btdc on both aswell which will be a safe setting.

I guess it wouldn't make much difference on a standard car then, with regards to detonation and whatnot - especially with it running rich at the top end.
So there is a difference in the parts.
I believe that they will both work and are interchangeable, but the maps are slightly different due to the timing; the Sunny has always been quoted as a lower power (in official literature) than the Pulsar because of that.
As Bobby says, the base timing is set the same so it makes sense the Ignition map is different to benefit from the higher octane fuel in JDM.
Thinking more widely, the speed limt is an ECU controlled function so the UK ECU will have this removed. Probably other things too, Ed might pass through shortly and explain all the mysteries.
Ed, just thought, if you do, can you post up the standard ECU's ignition map as I wonder how that compares to the PFC? I found recently that has a few different "defaults" depending on what datalogit software you use.

Is ? that to help with cooling when on full boost .

I don't understand the meaning of this sentence, sorry.
However, I should correct myself; the risk of blowing up is low when running the "wrong" ECU. It would definately make a difference to top speed at least.

won't make any difference as the engine's are the same,
steve - i'd very much like to add the factory sunny ecu bin file to my collection (been asking around for a while now) if you could email it to shalom @ gtiroz.net that would be super
stumo - where'd you get that 23710-69C00 part number? might be blind, but i can't find it in fast - only 23710-69C05 (a pic would also be great to add to the gallery below if anyone has access to one)
