IF you dont do any thing to your engine involving either change of displacement... change of compression ratio...or change in induction method then there's no point in messing with the ECU. Performance gained from fitting an aftermarket exhaust manifold and intake filters are still within the ECU's `fuel trim' capabilities.
But if you still insist, the I-VTEC uses OBD-II meaning that you can do a reflash of the EEPROM. Try throwing the wrench at Honda Malaysia.
what is the suitable engine management for I-VTEC
