2016 Peterbilt with factory ISX/derate historical codes
2016 389 that was deleted prior to our purchase. They are no longer in business so.... Here the deal.
We knew there were some issues when we got it. Replaced injectors and cups, fuel pump (HP and transfer), fuel sensors, cleaned tanks and lines, ECM cooling plate and after many issues replaced the ECM. Historical (non active) codes keep derating the truck after about 150 to 450 miles.
The only thing left I can think of is a poorly mapped tune or a faulty tune that is allowing an old code from the egr/def/filter assembly that is no longer in use.
In Alaska, need someone that can figure it out cause I've done all I can think of and the dealership is out of the question as they are still not working on any deleted rigs.
Thanks in advance
Scott

== Start by copying the program out of the ecm and e-mail it to me for a proper review of what someone did in there.

He is gone, out of state, closed shop a year ago. I don't have a sufficient programmer to get that info. Do you know someone in AK that can do that?
I can try with the link you sent, but will have to get an adapter to plug in with.

if you do not learn to become at least somewhat self sufficient, then this industry id going to take you for all your worth, chew you up and spit you out the other end with nothing but headaches and no wealth built up for all the years of driving.

get an adapter, get insite and CT,.. learn how to work on stuffs yourself to at least some medium degree.
