Hey guys looking for some info. If you haven't noticed in my sig that I am not a owner of a Ram pickup. I converted my 4x4 Econoline about a year ago. Used it all summer towed awesome ran flawless. Just at the beginning of September of this year the engine stalled. Attempted to get the vehicle to start no go. Hooked up a scan tool no communication. Installed a known good ecu engine fired rite up. Sent my back up ecu to have it flashed with the calibration that I began with and found that when driving under load the engine will not go over 2200 rpm's. In park and neutral the engine will rev over 2200 rpm's. I have a brand new fass 150, unrestricted air intake system, and no codes. For grins I did the lift pump volume test and it passed. Swapped out a known good map sensor still no good. If I lock the torque converter in first gear and at about a 15mph roll I can get the boost up to about 29 psi. I've let it go this long because of the fact that I work for a Ford dealership and we usually have alot of Rams traded in. Well of coarse no rams for about 3 months. And of coarse it has to be a non skim 04.5 auto only. Anyone have any good tests that I could go from here. Or maybe better yet a person with a 04.5 auto non skim truck that is near the portland metro area. Getting despirate here. The only good thing is the fuel mileage is awesome being derated at 2200rpms.

Thanks

 

Rail cap is leaking down???? Just a guess

 

Where are you ?? find someone with a smarty in your area to BORROW for a test... my 05 does NOT defuel @ 3500

so Like I said what city,state are you in... a fellow DTR can see if its the flash

 

I live in the Portland Oregon. I would be willing to drive pretty much everywhere. Every Dodge dealership that I have talked to over the last 2 years all really have just made me mad. Once I tell someone that I repowered a van with this engine their brains just shut off. I work on 6.4l 6.0l and 7.3l's. I cant get one Dealership to think out of the box. I am glad I have some little issues gets me more familiar with this engine that actually makes sense.

Thanks for the replies

Paul, it sure sounds like a communications error.
How did you handle the sensor/bus transplant?

Please give us more info on what came from where - CTD, 48RE, ECM, bus, etc.

Are the shift points OK? Did you do APPS adjustment?

 

Same things I was wondering.......add to that
1 -did anything preceed this problem or it was just bang, all of the sudden
2- any codes?
3- any guages?
4 - how have you been communicating with the ecm? Ford should have the protocol to talk to the ecm thru the heavy truck division if you have access to that. ( They use the 5.9l in bigger trucks f750 and so on)

 

I have the auto processor to go with the automatic apps. The trans I have is a 05 48re trans converted to manual tv cable lever. I tried to network the ecu abs and cluster together never worked. I sacked up bought the ats trans controller and valve body. Also picked up one of their five star converters. I drove it in this form for about 8 months with no problems whatsoever. It will forever will have trans codes and network codes just like the first day I drove it down the street. Didn't derate at all. Maiden voyage was a 33foot travel trailer. Driving the thing down the road and monitoring all the inputs they all look within spec
including the apps. Oh yea I hooked up the scp network with just the pcm. 60 pin plug in at the dash and it works great. I have been able to reflash and do other things including monitoring inputs and outputs

The '05 is drive-by-wire; sounds like you are essentially running concurrent (and probably conflicting) shift protocols.

 

What is the ecm seeing as far as rail pressure, map sensor, and apps?

 

Yes it sure is. Not sure what acceptable pressures are on the high pressure fuel
side. I think when watching it I was at about 24,000 at 2200 rpm. Apps shows appropriate voltage and calculated throttle angle percentage. Lift pump pressure 22 psi volume fills 48 oz in about 10 sec. Swapped a known good map sensor didnt make a difference.

 

Tried the 05 flash didnt work cause i needed the auto apps pre 05 to stroke my trans cable and also so I could use my oem ford cruise. The 05s are all pedal mounted sensor with idle validation input that doesent work like you say. I really just need to drive a known good truck and monitor everything. Plus ats diesel controller dosent discriminate on the voltage inputs for throttle angle. I am really running 2 standalone systems as we speak.

Thanks
Paul

 

I think that's the problem.

 

How do you explain it running perfect for 8 months without issues. The ecu has no control over the trans. It might not see the transmission electronics around but sure didnt have an issue for 7000k miles. I worked with this combo for about 9 months trying to get the junk electronics married and talking to eachother. Didnt work. Finally said screw it and put the ATS valve body and electronics in it. Not saying its not possible but didnt work for me. Other people including Autoworld of montana have run this combo in their conversions. Not taking any credit but they realized the headaches they were going to have to face. My guess my ecu that fried took something out with it. My guess is that im a sensor away of it working normal again. Other than the derating or lack of rpm the engine runs fine. If i had a Power Joke in my van I could have modules networked and running fine unfortunatly im stuck with mopar electronics. Seems if you look at them sideways they will fry. I talked to cummins inc they say the cummins for dodge is just that, built for dodge trucks only. They dont have the same cp3 and other little things.

Thanks for making my brain work to generate new views

 

Oh - didn't realize it worked fine with your current combo!

What fried your ECM?

Are the TC & OD switched-negative solenoid circuits properly grounded? Also, shielding for EMI noise can help eradicate bus gremlins.

 

Not sure what fried it. It just decided to be ****** off one day and smoked. Send to Doug Alm he said his software wouldnt even talk to the ecu. The tc and od inputs and outputs only go to the ats controller all trans wiring has been deleted since day one.
