DDEC II ECM life expectancy

[eagle19952]

Does anyone here with DDEC II have a picture of their heatshield?   I have only a small shield over the five connector plugs on the right side, and there's no sign there was any shield larger than that over the rest of the ECM.   I can easily(ish) make a shield from two layers of polished stainless sheet, but how to best attach it is not obvious to me right now!   I don't want to bolt it directly to the ECM because that will conduct heat straight onto the cooler plate.

Why did Detroit put their ECM right under the hot exhaust?   Surely they could have found somewhere else cooler to put it?

Thanks, John

not exactly what you asked for...but an illustration none the less ... ..... #12 is the heat shield

a home made/altered one ??

That's it?!?!   I thought it was something to cover the whole top, not just the connectors.   I already have one of these mini-heatshields.   I still think I'll make something to reflect heat away from the coolant plate itself and to cover the whole ECM.   I know it would be best to wrap the exhaust with some insulation, but that's another project-to-be.   I could attach my uber-plate using the four existing bolts that secure the ECM's tray to the thermostat housings, then nothing would touch the top of the ECM.

Thanks, John

Hi guys,

Monday the ECM arrived, was programmed, installed, tested, road tested, and we were on our way home. I have to compliment the team at Interstate in Bismarck on the way we were treated. They let us park in their lot, provided 20 amp outlet, and we're very nice. The tech was sharp, effeicent, and very pleasant. They also gave us a break on the cost of the ECM and labor. Hopefully this ECM will last.

I asked about converting to DDEC IV but the kit was $3700 plus the labor to install. Both the tech and service manager advised against it because the DDEC IV isn't sealed as well as the DDEC II and, due to the location, is exposed to water and winter salt on the roads. Corrosion can kill an ECM.

Thanks for all the advise and opinions, Sam
