I'm a little late on updating this one. In the end the ECM was not the issue nor the programming. The reman turbocharger was causing the issue mechanically. I had the rebuilder go through the turbo but they could not identify the fault. A new Holset turbocharger fixed the issue and the truck is runn...

Thanks

If I was able to reprogram in house, I would definitely give it a try. At this point the only option in our city would cost roughly $580 to flash the ECM with the Chrysler software. The customer is opting for a reman ECM that comes pre-calibrated. This issue started serval years after the delete so ...

I'm just wondering if there is a way to change my user name.

Just to update on this truck. It appears when it was deleted the stock exhaust was just drilled out. I did pull the down pipe off at the turbocharger and drove it again but the issue was still there. The exhaust back pressure is reaching 66 psi above atmospheric pressure when the brake is coming on....

Hi Ben, Yes, if you drive the truck under 50% throttle you can, very slowly, accelerate through the RPM range. To me it appears to be the sudden demand for acceleration that commands the VGT to 74% to spool the turbocharger up but the actual continues on to 94% closed which is the exhaust brake rang...

I will take a look at the PIDs tomorrow. I know there is an engine state PID but if I recall correctly it had more to do with the exhaust aftertreatment such as DeSoot or regen but I may be wrong. Good point again about the ABS. I did have an older Cummins have power issues with a shorted ABS wire. ...

Sorry, to clarify the CAN bus 'looks' 100% as in it looks good with no issue. Its not transmitting at 100% capacity.

2006 Dodge Ram 3500 6.7L Issue: This truck has had this issue for for several years. When accelerating above 50% throttle the exhaust brake slams on and will not release until the engine is returned to an idle for several seconds. The VGT position before accelerating is around 54%, matching the desi...

Great post! I will have to give this a try in the near future.
