There are several used and re-manufactured DDEC III ECM's on Ebay currently. Those would likely have to be reprogrammed to your coaches HP/torque, etc.
They are correct, if the DDEC unit bites the dust, you are stranded. There is a DDEC override switch on the dash on my coach but it is only meant to get you off of a busy road onto the shoulder and non-volatile memory failure leaves you in deep stuff.
There should be codes on your DDEC that an authorized Detroit dealer can use to get the correct program for another DDEC III.
