According a good contact on club s12:
"MKI has two plugs on the ECM and MKII has 3 plugs. MKI has vacum dizzy where as MKII has electronic advance. you can't put a MKII ECM in a MKI or vise versa. as for MKII tuning I know a shop that wants to crack the ECM they just need time and an extra ECM...so this is not going to happen anytime soon. My best advice would be to try megasquirt, and blaze new trail. there is also a guide to set a base map for it so that you can limp it to a shop to have it tuned. That is what I would suggest. It is cheap, easy to tune, and works with damn near anything. the only hard part is getting the right info the its ECM. There are tutorials however on their site. Do a Google for MegaSquirt and see what you think"

minor update, I've extracted the chip from a Mk2 ecu and scanned the rom image, and the fuel map is slightly different from the map that's doing the rounds on the net which I believe came from a Bluebird. so S12 and Bluebird ECU's are not identical (differences wouldn't cause much trouble though IMO)
I'm hoping to get the engine built and running on a chipped ECU by early march

cool, nice work.
I know its a bit cheeky but dont suppose I could get a sopy of the stock maps? or their location files? I really am seriously interesteing the in buying the ROM emulator and getting together all the kit to remap the ECU.

I shall be getting a burner to write the final maps to a fresh chip. But I would like an emulator so you can see what values are being accessed live for tuning purposes rather than just guessing.
All in you need quite a bit of kit. But finding the location files and getting a meaningful dump of the origonal chip is the hardest part.
