Ecm mileage after delete peterbilt cummins isx

.

Really usefull information I’m sure this shop use the same file for every peterbilt to every truck they work on

 

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. Cummins INLINE 6 Data Link Adapter with Cables ( J1939 500k truck compatible ) | eBay

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.

 

Yeap they fixed that

 

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?

 

I have no idea i really want to learn but not easy to find information. Truck start suffering the carbon build up cummins local shop told me it start using oil between changes about 2 gallons. Runs strong as always 25 psi in idle oil press. Normal temp no blow by no smoke in stacks. They sugest me to us the valvoline premiun blue restore to try to fix the issue

 

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.
