When tuning these vehicles via obd please ensure you read off the injector codes prior to writing the file on! As from time to time they can lose the injector codes when applying the calibration data. Once you have the read off and saved the injector code data it is easy to re-apply it after writing the mod file on.

For electronic key equipped cars only:

Remove the key from the electronic key holder Insert the key in the dashboard and turn it on. proceed with read/write as usual
