It looks like I may need to replace my ECU. My truck has been acting up as of late and all things point to the ECU. My worry is this truck is a lease and mileage matters. If I get a known good used ECU that has a different amount of miles on it compared to what my dash states would this be a problem? I would hate for the dealership to freak out when they get it back. The Gauge would be correct but if anyone would ever need to run a test down the road and see two different numbers all kinds of stuff could hit the fan. Am I over thinking this or is this a legit concern? I am almost positve that the ECU stores this info. Any thoughts?
