DDEC2 ECM repair or replacement

I'd check to make sure ecm isn't programmed to limit the speed and rpm first. My first choice to check it out is Pittsburgh Power. They are little pricey, but they are good and thorough, with the electrical engineers on staff. I've had 2 ecms worked on by them, and once they found a ground problem-when I only brought it in to be reprogrammed-that was not worth (just about beyond) repairing compared to buying another. And the price for that ecm was just about as cheap as any as I could find on my own (yes, I checked pricing after I gave them the go ahead to get one for me). It's been a while, but ecms were fairly expensive. I don't think you will be charged much for diagnosis with anyone.

 

Whwre are you located? I can let you borrow one to try

 

Diesel Control Services - Fernando.

Wouldn’t let me post link.

 

Or them too. Fernando used to work for them and went out on his own.

I had my DD3 worked on and tuned by him - full test benches, worth the $.

I'm outside Ft Smith, headed to Sioux Falls Monday. If you'd be anywhere near those places i'll drop it off, or if anybody you know coming through here can grab it.

I'll PM you my #
