This is my first time needed to tune a 2015 challenger. Ive read the stick on the 2015 through 2017's. My customer is an elderly man who takes care of his sick wife and can't go without the car for a few days. What are my options? can I buy a new ecm somewhere (other then the dealer? my local parts store can't get one). Am I better off getting a used one from a wrecked car? What's the easiest way to go? If I buy a new one or one from a wreck, how do I know which ecm to go with? Are all the 2015-2017 ecm's the same? I've tuned hundreds of gm's but this is a first for me.
Thank's in advance for any help and pointers!!!!
