DS4 to DB2 conv. litterature

[dantheman]

i am swapping my DS4 for a DB2 and was wondering if anybody had any litterature on this conversion, especially as to what components need switched, added, deleted, modified, etc. thanks

I have two trucks, one with each system, I would not attempt to convert the DS4 to use the DB2 IP. I have the accelerator pedal and cable, but what is going to control the transmission when the accelerator module is removed? Also the ECM gets engine revs from the DS4 system, the DB2 from a separate sensor. It could be done using the DB2 computer, sensors, and harnesses from another truck.

Pump swap is pretty basic and staright forward. Pretty much just swap them. You will then need to convert your electric throttle pedal to a manual (cable) type pedal. Make sure you get a bracket for you ip and throttle cable. You will lose your cruise control though. You will need to convert your wastegate actuator to a manual watsegate, ecm controls vacume and turbo boost. You can then delete the vacume pump, lines, and solenoids. not sure what actaully controls auto tranny in your 94 (if your running a manual tranny then that would be easy) Also im not sure what what kinda speedo drive you have (electronic or cable) if electronic then im not sure what contols auto tranny and speedo readout. and of course you will have to live with the service throttle soon light bein on, and check engine light, unless you remove the bulbs.

friend of mine did such a swap, but he put the engine in a 90 truck, with manual tranny. Swapped injection pump and fabbed exhaust and was pleased with the result. ( and hes a ford and cummins guy and the chevy 6.5TD is his service truck, go figure LOL) .

He has electronic speedo, and engine revs, all sent to the ECM, not easy like your friends 1990 model.

Yea, i knew my friends was easy. And this ones gunna take sum time and thought. Pump swap is easy, the dash electrnics and tranny control are gunna be really tricky.

Grancito is right, the easyiest way for him to swap would be to find a junk 92 or 93 with a 6.5 and swap the complete wireing harness and such. as long as tranny electronics are the same and the 93 Tranny control module will control the 94 electronic tranny.

I wish i had a non-dlectric inj. pump.

...rebuilt to hydraulic shift,wrecking yard for pedal pivot/cable assembly...mechanical pump...tach already comes from oil pump drive on auto...mechanical wastegate control...once you get this far,you have a usable ,drivable rig...now you have to shake out the bugs...or you can just find a pre-94{93 back}truk for a doner...jd

ok, thanks, my 4l80e is toast so i'm goin with an nv4500, so that part will be easy, then i'll have to work out the electrical problems as i go, unless i can find a donor truck, so if anybody has one let me know please.

I have an entire wire harness from a '93 truck....let me know if you need it? i can take a picture if needed...

yeah how much would you want for it? and does it have the computer with it?

[JD_countryboy]

93 only had a computer for controling auto tranny. dont need it if your gunna run a manual tranny.

oops, good call

[kbarkley]

60$ for the harness plus shipping, I have the '93 glow plug controller too that Ill throw in with it as well. Everything is there though, even some batt cables. I have other misc parts if your looking for anything else

[dantheman]

sounds good on the harness, and i'll let you know if theres anything else i need once i get a little farther into this project
