Ecm

[Scoot5869]

I may be needing a new ecm for my truck and I was wondering since I already have the programmed file in my computer do I still need to have the dealer put the factory files in it or can I just pop it in my truck and hook up to insite and load my existing file and be on my way? Also if I had my programming fixed a few years ago would it still fine or has the tune been updated. Thanks

When buying an ECM, ALWAYS buy it OEM,.. never off the interwebs or used, and ALWAYS have the stealers$it pre-flash the ecm so that it can run your truck before leaving there with it. This is cheap insurance that you have a good ECM. The moment you walk out of that door from then, you will have to buy a whole new one and wait months for your moneys back if there is anything wrong with it and/or f it does not work for any reason.

Ok thanks I will have them pre flash it with the factory file then. Would my truck have the latest version of mm if you fixed it four years ago now I think

If you send me the updated factory flashed file with 10 minutes of engine run time on it, then I can do it up with the latest version.
