Which ECU do you have in your GT? Options

[tomr96]

Hey all. I have a '96 'vert with a 5sfe and manual transmission. I am not the original owner. The car has this ECU 89661-2D410. The local dealer says this ECU is not spec'd for the Celica. Could all you 6th Gen. GT owners with manual transmissions respond with the part number of the ECU in your car? Also the model year and whether it is Federal or Calif emissions. Thanks.

Thanks 97GTinKC. Yes, the production date indicated on my car is 9/95. I am aware of the TSB. My car behaves exactly as described in the TSB - at slight throttle openings and light loads, such as when going downhill, the engine bucks and surges as if it can’t decide whether to accelerate or decelerate. It drives me nuts. Unfortunately the ECU that I have is not one of the part numbers listed in the TSB as eligible for the improved ECU. Even if it was, the car is way beyond the warranty period. I found an ECU from a '98 GT (5sfe, MT, fed, etc.) for less than the prices indicated at the link. Anyone here know if an ECU from a '98 would work in my car? The wiring diagram, etc. in my shop manual appears to be the same for '96-'99 (OBD-II, etc.). Anybody?
