Specifically I went from:
AV10144 CPL 3320 to
AV10069 CPL 2732.. This is in a 389 Peterbilt.

Is there settings that should be copied over from the original engine cal?

program differences show...

* very different DPF types/flow, and settings. A de-manded truck this would not mater.

but...

* VERY different size injectors with very different settings. <- according to your post, you are using the wrong program and are not using the correct injector programming at all. the 2 don;t even have the same offset angles,.. nothing. <- I see all kinds of efficiency losses every time I have seen someone do this.

* the AV10144 assumes the large injectors seen in the 550+ engine specs. The AV10069 assumes the smaller chambered mid-tier spec injectors.

* injection timing is thrown out of whack due it assuming a different chamber size for the injectors.

* the programs are meant for 2 different size cams, 2 different types of pistons, 2 different types of valve cams, etc. <- de-mandated or not, it is not right to use one program for the other at all. Whoever told you to do this or did this needs their head examined and if they disagree, they are welcome to come over here and I will sit down with them line for line in the program and show them the error they are overlooking. It is significant.

The list of incompatibilities is quite long for this kind of mis-match. I would suggest you get the correct program for that engine and truck set into that thing so that you aren't wasting thousands in fuel every year,.. or worse,.. cause it to burn a hole in a piston or something else.

maybe I'm outa whack here but I though he got a entire drop in engine for his truck? He just went down in Cpl with all the hard parts to match?:angel:
