ECU Identification

[Mace]

I'm in the unfortunate position of having a car given to me not running and in parts. I have the ECU in the car can anyone confirm weather this is the original uk spec ECU or the JDM ecu and how do you tell?

Looks like a jspec TT ecu... But I've never seen a uk spec...

[Mace]

Thats the problem, I would have thought the uk spec ecu would be the same looking but the difference means that this car will not run with the wrong ecu. Bit of a big deal to getting this thing running ..

What is the part number on the label? A quick check on the EPC will tell you what model it is from.

These are the part numbers for the UK Spec Supra.
