Well dodge says this ecm that i have is unprogramable. Depending on the year some could get flashed once and some are re- flash able. Anyone have any onsite on this topic. They wanted to sell me a 1500 dollar new ecm and I said hell no. The truck runs good, just wanted to get the latest software in it

Update. The ecm has been in for two weeks now and no probs so i think I got her licked. Since the ecm is out of an 01 I'm going to dodge to flash it with the latest software. The ecm was out of a blown up engine so the guy gave it to me as long as I bought an exhaust system from him. No prob I said

Thank you for all your responses and support guys. I have located a test engine ecm that a guy will loan me in town so once I get that put in, hopefully Thursday night we will see how the truck runs the rest of the week and weekend. I will keep u posted on how it turns out. Happy wrenching!

I've checked for air in the return and its all clear so no air. I forgot to mention that it does this intermittently and runs great when cold. After warming up and running for awhile the dying comes back only with cruise control and then sometimes with the throttle pedal. All guages stay working and no warning lights. All is stock on this engine.

Hey all, I have a 2002 cummins 2500 SLT, manual trans, 4X4. The problem I have been having that just started a few months ago is the engine with die and then come back on going down the highway. The engine will do this on off on off surge like someone is turning the key on and off very fast. This will happen with the throttle pedal and or the cruise control. The fuel system is solid with a fass fuel pump and I have verified 15psi at my VP44. I have cleaned all grounds and verified wiring connectors are tight and problem free. I have no codes and have verified that I have no ripple effect coming from my alternator. I stopped in at a dodge performance place and went for a road test with a scanner hooked up. The tech showed me that in the PCM screen real time, the fuel shut down was changing from on to off very fast and causing our surging problem. I'm at a loss being a diesel tech for caterpillar I have tried everything that I can think of. Can someone also clarify what the ECM takes as an input for throttle. IE ( APPS and Cruise control) Or does the PCM control cruise control and the ECM controls throttle from the APPS only. Thanks
