Maybe it's the standard JECS ECU (i wasn't aware they did uprated ones for our cars) with an aftermarket chip. That could be why you've been told it's uprated.

P.s a pic would sort it out (inside and out).

Mine's a MY95UK & it's got JECS slapped all over my ECU

JECS make the whole engine management system for the cars, including some sensors, the injectors, MAF sensor etc.

If there is anything plugged into the 28pin socket on the ECU circuit board then it's most likely an aftermarket chip.

However, all 91-00 cars use JECS ecus, just like european cars often use a Bosch management system or similar.
