Finally fitted my newly purchased ECU from a JDM Corolla.
6000rpm lift (UK ECU 6200rpm)
8250rpm limit
99ron mapped (UK ECU 95ron mapped)
Nice little bang for buck upgrade at just $50 delivered from the U.S to UK. Defo seems to pull a bit harder, and the lower lift point will also help on track.
Most run the Celica JDM or early U.S ECU but these are now getting on for $300 delivered to the UK.
My car was already running the UK Corolla ECU, so this was just a plug and play fit.
For anyone interested in this ECU the part number is 89666-12260.
