ECUs need to be VIN matched by the dealer. That is likely why you are receiving codes. Also if the ECU you received was not a Euro spec you may throw codes as it is not seeing what it expects. An Aussie member had the same issue with emissions codes getting thrown on a non-Aussie spec ECU.No I just removed the stock ecu and replaced it with the new. Then let the car on ACC for 30 sec (saw sfr video) and did this 3 times and then started the engine.
Sorry, don't know if this can be done.999RXerox , Do you know if there is an option to install the sensor/s that are the reason why we get those codes with the korean ecu?
John from Tork Motorsports told that the code wont harm the engine or car but i am looking for a way to get rid of them in case i install stage 1 on my spare ecu.
