Low mile used ECU. Direct replacement for all 2000-05 Celica GT Manual, North American spec. Likely works in other cars worldwide but may get check engine light if emissions equipment is missing (Japan market cars have no fuel tank pressure sensor for instance).
This ECU can also be used in 2000-05 MR2 Spyders (with original 1ZZ engine) as a replacement for a damaged or missing ECU. It will offer the same performance as your original ECU but has no immobilizer so it can be installed with no reprogramming of immobilizer and keys. Minor wiring changes are needed to the wiring at the ECU – instructions are provided.
