Any Cummins ISB gurus here?

I have a 2006 300hp 5.9 Cummins from a motorhome that I need to take the EGR circuit off it. Has anyone here done this, or know who has?

You'll need EGR block off plates. You'll also need to have the ECM custom tuned to dump the EGR and DPF crap. Might want to contact smarty power or H&S to see if they can help you with a programmer/flasher, since that doesn't have the same setup as a dodge truck.

Ditto to above.
Bully dog had delet for the cummins and flash programer to.

What do you wanna do? Still got my #? Give me a call.

Hey Gerald,

Smarty, H&S, or Bullydog cant do anything with your programming, they are setup do do strictly Dodge Cummins programming, the industrial motor has a completely different ECM. Also there is no DPF do deal with, that engine would have had EGR only. I will try to get you the number for Chip with Blue-Chip diesel, he does the programing for the module that TCS and Banks sells for motorhome applications. I still think Cummins can do it with the Insite software.

Ahh if that's the case, just get the EGR block off plates, leave the EGR solenoid hooked up to the harness (but not plumbed in). And let it ride.

That wont work either, not only does the ECU look for resistance at the solenoid, it looks for a change in intake air temp to monitor EGR efficiency. Been there done that... Just going to have to pull off all the garbage, replace the air intake horn and exhaust manifold with a non EGR set, have cummins reflash the ECU to a NON-Emissions CPL or put a piece of duct-tape over the check engine lamp and run with it... lol the industrial engine has a diagnostic lamp, a check engine lamp and a shutdown lamp, the diagnostic lamp will flash codes when the ECU is in diagnostic mode (either with a switch or by depressing the throttle 3 times after key-on), the shutdown lamp lights when a critical parameter is out of range ie. oil press, temp, etc. and last of all the check engine lamp lights when a non-critical parameter is out of range or a trouble code has set like " your EGR valve is missing!!! "

Sounds like the same setup the wife's jeep liberty diesel has. Since there isn't a non-egr flash for it. (And I didn't want to buy a GDE, Kerma, or Inmotion tune) I chose to use the SEGR box. I did have to cut the engine harness to install it, but it's not that involved. It "tricks" the ECM into thinking the IAT and EGR are still working. But if you can flash it, that'd be easier.

I'm kinda stuck until I can get some info on what I can remove. The turbo piping and intercooler configuration, along with the lower side of the radiator piping will be determined after I get the EGR part resolved. Guess it's time to move out of the engine bay for a while.

Not to worry, there's plenty to do on the exterior as well

Thanks guys for the continued input!
