ECU part number - CAT equipped cars
Discussion
Ah, I've since found a reference that says that the 90GB-12A650-GA ECU is a 2.9 12v CAT ECU.
The reason I was trying to find out the ECU part number is that I have a Superchips module for a 0GGA ECU which I guessed was for cat equipped cars. Oh, and 0GGA is the abbreviated code for 90GB-12A650-GA in case you were wondering.

Mine is a 2.9 12v cat engine too. The ECU does state 0GLA elsewhere on the housing.The reason I was trying to find out the ECU part number is that I have a Superchips module for a 0GGA ECU which I guessed was for cat equipped cars.

Will the chip fit yours? Are they any good?
Has anyone ever considered fitting a cat ECU to a non cat car?
You'd have to add the lambda sensors into the exhaust system (and wiring presumably) which is a bit of a PITA but you could do away with the airflow meters.
You do not need cats to run the cat ECU if your car is of pre cat age.
The advantage is that you have some feedback to the ECU going on - so the ECU actually measures whats coming out of the engine in the exhaust and adjusts accordingly.
Pre cat predicts what should be coming out of the exhaust but it doesn't actually know if thats being achieved.

I don't see the point of fitting a factory cat ECU to a non cat car with all the hassle and then still have an ECU mapping geared more for economy/emissions. Better off getting a mappable 3rd party one if you're going to go to the trouble of doing it and then it can be mapped for more power - not that you'll gain much I expect.
You'd be better off fitting a new cam and enjoying the boost that gives.....

I've got a load as spares which is the best way to guarantee that they never fail. There are always some on fleabay if you look carefully. Someone picked up a recon unit for about £8 plus postage the other day which seemed a good price and I picked up a pair for a tenner delivered a while back. However when some muppet posts links to an ebay "bargain" on this forum, then the prices rocket.
