There is no mileage reading in the ECM either. Actually anything that is not hard coded into the ECM from the factory (or us) is erased when battery power is removed.
Fantastic. So IF I was to purchase a 2nd ECU and tune it and then swap back my "stock" ECU no one would be the wiser? Or if I wanted to go the cheaper route I could flash my ECU and then flash back to stock for service and no one could figure out I did a tune.
EDIT: Thanks for all the info!!
