hey, i have an 89' turbo myself, good year! aside from some troublesome ecu's. you must use an 89' turbo car ecu. ebay is your best bet or if you get lucky a wrecker. too bad you not close to me so you could try my ecu to see if it was the issue! good luck and i'm always searching for stuff so if i come across one i will pm you.

If the US ECUs for 1989 are the same as those for the UK, then you could swap to a different year. We did that on Alex's car. The ECU kept frying AMMs, which are nearly impossible to find for MY89.

We swapped both ECU and AMM, and swapped over wires in the AMM's connector for compatibility. More information here:

Doing that means you lose the dodgy MY89 ECUs forever.

Matthew is correct, you do NOT have to use an 89 ECU on an 89 car. if I recall the 89 uses a pink label 0 280 000 570 (the last 3 are the important numbers, all the first few are the same for all ECU's) you can use any 1989-1993 900-Turbo ECU, I'm not sure about the UK models, however every 900-turbo 89-93 that I have seen has always had a 0 280 212 013 AMM- so that should not be an issue. some of the ECU's that should work are-
0 280 000 948,
0 280 000 566,
0 280 000 582

or of course the original-
0 280 000 570

From what I know you (dealership) has to send it in to get fixed, still costing alot of $$.....easier just to keep an eye out for another on ebay for $50.
