Ecm mileage after delete peterbilt cummins isx

Head over to Rawze.com... Ask for an invite and describe the problem. Do you have an Inline 6 reader to see what is going on in the ECM? If not, you will need one. This is what most of us use on our Cummins motors, they ship quickly, usually have within a few days of ordering.

You will need the CPL file number from that tune, an Inline reader will be required, and you will need a laptop to use it running Windows 7 or newer.

The CPL number is on your engine data plate. Odds are is does not match the file in your truck. This can lead to all sorts of issues, none good.

 

There is a LOT of garbage out there. Smart move selling those off.

 

I would really try to find out what they did to your motor. There are other issues too, the liners in the 2250 and 2350 do not like higher HP. Also, did they mess with the EGR cooler? Plate, weld or remove? That cooler is needed to cool the #5 and #6 wet liners. Cut those off, and they tend to do bad things. Then the fuel pumps, you do know about them?

 

Two gallons of oil is not good, it is going somewhere... Head over to Rawze.com, there are guys there that can help, sounds like you have a hack job tune on there. Do you have a turbo boost gauge and a Pyrometer gauge installed?

 

Im looking to get it done so is it better to tune out def and leave the egr alone ?

 

Ask that question on another site. The forum owner has asked that we don't discuss the particulars of performing emission modifications.

 

Ahh yes sir.
