Swampy442 Posted March 25, 2020 Share Posted March 25, 2020 I have a few Aristo auto ECUs, whilst not a permanent solution (your dash will light up like a Christmas tree) it will operate the engine and box fine Link to comment Share on other sites More sharing options...

Mika Posted March 25, 2020 Share Posted March 25, 2020 (edited) You will most likely going to need to have the General EU A/T ECU, Toyota part # 89661-14530 if your car is general Euro Spec Auto Supra. There might be some issues if using Austria / Switzerland A/T ECU, Toyota part # 89661-14550, as the Austria / Switzerland A/T ECU is programmed for different part # auto transmission and differential. But it also could work as it should. Theres also a possibility to use USDM A/T ECU Toyota part # 89661-14510 / 89661-14511 as the engine wire harness is same between US/EU Supras, but US Supra ECU`s does not have as good ignition timing and fuel charts as EU ones do. Also the differential and auto trans are different from the Euro Spec Supra. Edited March 25, 2020 by Mika (see edit history) Link to comment Share on other sites More sharing options...

Thanks for the reply, have talked to toyota, and they say i need ecu with this number. 89661-14531, does that sounds right? Link to comment Share on other sites More sharing options...
