MTX75TC Posted March 11 Share Posted March 11 I was on here a while ago and got the mechanical swap completed . I tried everything available to keep the original pcm , but it's not going to happen. Too many obstacles as far as Sync , body modules and lack of similar pcm settings in other ford products with similar pcms. So I am swapping the entire harness , modules , pcm, cluster , throttle body , egr manifold-or modify stock on this transit connect to a 2005 pzev duratec manual zx3 Focus gear .

Fifty150 Posted March 11 Share Posted March 11 Wow! Amazing. Can you recap for us, the project timeline? MTX75TC 1 Quote Link to comment Share on other sites More sharing options...
MTX75TC Posted March 11 Author Share Posted March 11 Did the mechanical swap about two years ago . I used an SCT tuner and the Advantage racer software to get rid of all the auto related codes . It dives nicely for anywhere between 15-50 miles and then goes into limp mode . Tried to figure out what's not happy with Forscan , it really helped . Forscan let's you see codes that don't show up on other tuners / readers. There were many u-xxxx codes , lost contact with other modules . Then a few months ago I found a duratec manual trans focus zx3 . Now it's time to swap all the harnesses, modules ,cluster, cable driven throttle body etc. The real beauty is this will get rid of the Sync system. The speed sensor has to pass through APIM - accessory protocol interface module, on the transit it part of this Sync garbage. I plan to document it all on here so stay tuned .

ftcdriver Posted June 25 Share Posted June 25 (edited) Hey, thank you for posting an update on your van. I recall seeing your old posts and a video where you drove the van . Anyhow, I was planing on swapping mine as well and I wanted to try to keep the automatic pcm in place. After much research, it seems that it would require a simulation of the tcm to work properly. In theory, this is what has to be done 1. simulate the transmission codes on the canbus network 2. simulate the transmission switches output to the pcm (ground switches that indicate in what gear the trans is) 3. simulate sensors of the transmission Here is what I had done: - logged the communication of the canbus network - retrieved (not confirmed yet) the automatic transmission gear codes - basic research on usage of the pcm pins canbus analysis On the canbus network, the automatic transmission gear codes id is x230 and here is the data for each gear. When the van is off and the shifter goes through all gears, here is the data that I get: park : 00 64 D3 00 00 00 00 reverse : E1 08 D3 00 00 00 00 neutral : 00 64 D3 00 00 00 00 drive : 11 19 D3 00 00 00 00 first : 20 95 D3 00 00 00 00 second : 11 19 D3 00 00 00 00 (But I'd have to check again the park and neutral codes as they seem the same) pcm pins These transmission gear codes correspond to the 7 switch pins (pins 8,13,14,20,30,35 and 41) on the PCM. Aside from that, there are a couple of pins that would require simulation - 4 sensors (pins 10,19,29 and 37) - 6 solenoids (pins 23,33,43,44,45 and 50 but pin 11 and 15 could be deleted) - 2 other pins (could be ground or power control) (pins 43 and 50) So, simulating the transmission in order to fool the pcm would be a bit time consuming. The temperature sensors would not be all that bad, but simulating speed and matching gears could be a little bit tricky and would end up messing some PID's. At best, we might get final drive ratio error codes, but worst case PID's would be very off and throwing a bunch of codes (ABS, Transmission, Gear ratio...) Plus, using the manual tune with the proper wiring is a plus as the pcm uses the clutch switch to adjust fuel/air ratio depending of engine load. (Source for pcm pins and clutch switch : workshop manual) Anyhow, I hope the canbus codes could be hopeful for anyone that wants to keep the auto tune. Props to converting yours to manual! Note : that is all that I will to for the manual swap as I am getting rid of my van due to the engine going bad Edited June 25 by ftcdriver typo Humphrey's Van and MTX75TC 1 1 Quote Link to comment Share on other sites More sharing options...

ftcdriver Posted June 27 Share Posted June 27 Thank you, but it's alright. It happens I did enjoy having a converted (camper) fuel efficient van. So, I hope that someone takes it and fixes it. I'm now building an overland 4x4 suv, so I'll miss the space and the fuel economy that's for sure! Good luck to MTX75C and to you Double Nickels as well. These vans are awesome!

MTX75TC Posted June 29 Author Share Posted June 29 Got a little progress to report , everything removed from the focus . Been playing catch up with work since having both shoulders replaced tho , so it's been slower than I was hoping. I'll have some interesting pictures in a few weeks tho . Can't wait to let this thing rip on the freeway without the bill gates dashboard, yay ! Donor focus has no abs ! Makes the conversion a little easier, and I actually like non abs brakes better . See you guys in a few weeks with update and pics . Double Nickels 1 Quote Link to comment Share on other sites More sharing options...
MTX75TC Posted September 1 Author Share Posted September 1 Finally got all the parts from the focus I'll need and then some . Humphrey's Van 1 Quote Link to comment Share on other sites More sharing options...
