Have someone hook the little black box from cummins to isolate the IP from the ECM. It may save you the cost of an IP. I just posted this in my thread.

Well, I think we are all wrong. I got in contact with a guy in town that has been the diesel tech for the dealer for a few years and he brought out a DRB. It found nothing. Then he unplugged the IP and plugged on a little box from Cummins and fired up the truck. The cummins box powers the IP seperate from the ECM and it idled like new. The box also has a high idle and it was crisp and clean also. The little black box won't let us test drive as the IP is isolated from the ECM, but I think I've lost ANOTHER ECM. So, I would like to find one I can borrow for a test drive before I buy a new one. I got this used one from Bob Wagoner for a great price but I think I've learned my lesson with used electronics. So, I want to try one before I drop 300-500 on a new one. Beats a grand for an IP don't it! I'm stoked....j/k..it is still half a grand. :hehe:
Does anyone have an ECM I can borrow for a test drive for an 02 6-speed? I'll glady pay shipping both ways and get it back to you ASAP.
THANKS TO POWER RAM 4X4...my newly found LOCAL diesel tech!!!!!
