i just traded in my 00 ctd for an 03 cr.the new truck seems to have been flashed with a downloader of some sort.how can i return the ecm to stock so that i can use a smarty or some other product?the dealership told me there is nothing they can do and i would need to buy a new ecmis this true?if it is and i leave the truck like this would they be able to run normal diagnostics on the truck in the future?

 

As far as I know they can run diagnostice.. They ran the scan tool on my truck with the smarty on!!! I believe I have heard that they can re-scan your ecm but don't know?? ? OR how much???

 

It can be done,but if they don't know how you might want to steer clear of them.............
