Got a unmarried key on my procession and I'm planning to take the car to the dealer so they can pair it.

My questions are for those Mitsu Techs out there.

How is this process?
Do I need to put the ECU tune back to stock?


My worry is that for some reason they need/decide to reflash the ECU and decide to go on a joy ride with the boost pill on.

 

They will log into the immobilizer ecm not the engine ecm.

You can simply tell them you dont want the engine scanned or updated.
