Does anyone have information on how to tell what year and model a 1JZ ECU came from? The shop that built the car years ago thinks they used an engine and wiring from a 90 or 91 Supra, but the shop that is working on the car now thinks the engine and ECU were from a Chaser or something other than a Supra.

Is there a code # or symbol no the ECU that identifies what it is from?

Thanks for any help you can give!

Well there are ways to tell where the engine came from so if the shop used a clip then whatever the engine came from then so did the ECU. Why does it matter where the ECU came from anyway? Just wondering if there a problem or something.

Does it have "TRC" on the throttle body?
If so, then not from a Supra.

Chaser ECU fits a Soarer harness......... but if your running the auto tranny, it will slip.
