Before the questions come it was programed by an admin

I am the only Admin on this forum.. and I did not program your ecm that I can see.

If the programming is in question at all then e-mailed that program to me for a proper review, or have the person who made it send it to me if need be.

However, 1117 faults are not usually programming issues. It is either a bad ecm, and/or bad wiring making it reset without the key-switch being cycled and/or a faulty electrical system causing power surging somewhere.

If it is shutting off randomly them smack the top of it.. if it shuts down or stutters when smacking it.. then it is a bad ecm. CM871 ecm's are notorious for this issue when they get old.

Also.. if your buying non-certified ECM's,... that I can tell you right now that you can purchase 10 of them and only maybe 1 or 2 would be any damn good... bad CM871 ecm's are a plague among those people who 'repair and sell' them. The electronics in them are only considered reliable for 8 years and after that it is a crap-shoot, especially if someone is repairing it.

I can't tell you how many people that I have met who tried to buy 'repaired/refurbished ecm's' form non-oem facilities only to go thru 3 or 4 and get sick of it before they finally purchased one from an OEM.

OEM certified remans: - It is not cost effective at all for the red engine maker to do board-level repairs on an ECM or other related type of electronics. They simply replace the entire circuit board with a new one. As far as I have ever seen, they even do this with turbo actuators, and all of the other things with a circuit board in them.

Those boards are manufactured at their own partnership facilities (usually in china) for pennies on the dollar and there is no cost effective benefit to pay a labor force to repair them on a component level at all.

That is why when you get a certified reman ecm, the outer frame looks used and usually worn.. but the connectors are all brand stinking new. They do not replace the connectors or any other components individually. They replace the whole damn board at once because it only costs them wholesale, a couple hundred bucks instead of having to pay a labor force for some fool to figure out what is wrong with the old one. They also already know that trying to revive parts that are usually more than 8+ years old by the time they went bad is an unreliable repair any ways.. so they don't bother.

Call around until you find a certified OEM ecm.. make them bench flash it for your truck so that you can just install it and go. Have this done BEFORE picking it up, so that you can just hang it onto the side of your engine, run the engine a bit, and test everything out + troubleshoot your power/fault issues. This BEFORE having anyone touch it to de-mandate it.

Solve its problems first.

Then once those problems are resolved.. do you find someone who is recommended on this forum to help you get it flashed with a properly reviewed de-mandate program if that is what is needed.
