Presently have a DDEC 2 in our bus and am wanting to know how hard and how costly it would be to upgrade to a DDEC 4? What are the advantages and or disadvantages? Reason for asking? I found a killer deal on a complete BRAND NEW crate engine but it is built as a DDEC 4. If the price wasn't so good I wouldn't even consider it but it's really too hard to pass up! Ace | ||

Ace I installed a 6V92TA DDECIV from scratch as I had a mechanical engine before. I have the wiring diagram for this but you might want to phone your local DD outlet as I think there is a wiring adapter from DDEC2 to DDEC4. You will need to know the pin connections on your new computer and the old one as well. It can be read by a ProLink 9000. When I installed mine it took 3000 ft of wire and a long time to do. Good luck. Bill | ||

Actually It's even simpler than you think - #1 - You DON'T NEED need the "DDEC-II to DDEC-IV conversion kit #18sp546 - ALL those wiring changes and adapter changes and 2 new sensors (air temp and ?) are ALREADY installed and wired on your DDEC-IV replacement motor #2 - The Cruise Control wires connects (up front on the dash) on the DDEC-II can be SLIGHTLY DIFFERENT - a VERY simple change #3 - three (2 wires plus a shield -(J1939 communications) have been added. This requires a new diagnostic plug #4 - You'll need to get a multi-protocol & DDEC-IV cartrige for your PRO-LINK NOTE-> The DDEC-IV monitors more parameters - records better SNAPSHOT data - proviides many more - USER settable options than the older DDEC-II Pete RTS/Daytona |
