Back to the emissions and inspection, my statement remains the same. You need a new map/tune for the usdm ecu because you want to pass emissions/inspection.
filled it out. It's in Toronto and I plan on doing a 94 octane tune in the future once I get used to the 91 octane power. In Ontario, Canada emissions laws are now using OBD II and not tailpipe. JDM ecu won't connect and I need a WRX ECU (which I now have). If i can avoid paying $500 for a tune and flat bedding the car to a tuner that would be good.. is there anyway to just use the existing tune on the JDM ecu and put that on the WRX ecu?
