The DDEC II ECU is very reliable. It's cooled by fuel running through it. Probably a good idea to keep the tank toward full or install a fuel cooler since our fuel tanks sit inboard and don't get any air while going down the road. Since the...

How did we get from DDECII to Cummins M11?
Why do you think you need a DDECII ECM, What problems are you having?

Stump,

I was just generalizing as anyone with an electronic engine could be faced with finding a shop to repair or replace their ECU.

Thanks all!
