Yaris 06 1KR4-FE 2SZ-FE engine ECU swap

[Pearse]

Hi Guys 

We recently fitted a 1.3L 2SZ-FE engine to replace a worn out 1L 1KR4-FE. Having problems with locating a ECU that is suitable for original wiring loom as the new 1.3L has bigger plugs. Any Ideas???

Thanks

You need to swap the engine loom, ecu and then program the vin and immobilizer (may require a new module and ring)

Also be aware there are Jap and French built cars

1KRFE - 1.0 3 cylinder if it was a 1.0 4 cylinder, it will be a 1SZFE (very late Mk1 yaris)

Thanks We have a donor car so parts aren't a issue only merely the work required 🙂 Thanks for the help
