I'm replacing a very Tired 6V92TA with a near new DDEC11, If I change the Camshaft/Injectors and the Govenor have I got it covered. Going into a Australian 40'Tag axle Motorhome. the bus is 1985 without DDEC Electronics. |

The heads, crank, block, blower end plate, blower shaft, and a lot of other parts are different. Some will interchange backwards. The block is different due to the additional sensor drillings.
Still, if you have a donor vehicle with all the DDEC components, why not use the DDEC system. DDEC II is a good item. You'll love the TPS throttle.
Has cruise built in too.
Most of the work would be pulling the harness.
An MUI drives the gov off the blower end. A DDEC blower end isn't milled for this adaptation. No doubt you could use your blower.
Likely that some of the DDEC parts would work on your MUI...even with different part numbers.
The Yahoo Groups Detroit Diesel guys could accurately answer your question.
I found the above by looking up the two engines part numbers.
Best, JR |

BTW, on a DDEC II, all of the DDEC electrical components are located on the engine. Even the ECM is engine mounted. Only a couple relays and switches, and the accel assembly are mounted separately.
The only programming that would be required is removing the automatic commands from your ECM. A DDEC II is programmable. Would require a DD dealer...a good many marine dealers could do this programming.
DDEC 1 (first version) is a wiring nightmare, with components all over the bus, but DDEC II would make a pretty easy, clean install.

I think if you keep the DDECII system you will like it. I put in a 6V92TA DDECIV with an ATEC V731 about 2 years ago and have really enjoyed it. It only took 3000' of wire to convert. It was a lot of fun doing it. We did a 7,000 mile trip this fall without any problems.

Thanks JR and Bill, We've gone the route of just changing the parts I've previously listed, we couldn't locate a wiring harness to start with and building one from scratch was going to take to long. Hopefully the motor is going to operate at close to the DDEC's output. Our Motorhome has been of the road already for Three weeks. Thanks for your replies and help rgds Brett |

If you used your cams, injectors and gov, the new motor will operate at exactly the same HP as your old motor...plus the 'fresh' factor. A worn engine would be down on power.
For future reference, post what you had to change out to get the engine back to MUI.
