Transplant almost done. Pointers and guidance wanted

[creekrat]

OK. I got my truck's transplant in and just about finished up today and was able to read the tune file. I went ahead and made a few changes to it for my swap. Apparently the engine and trans (5.3 and 4l60e) went in to a 1993 2wd c1500. Turned off VATS and set auxiliary fans. If anyone can give some insight on any other things i can change that will help wake the beast up then by all means tell me what and where. I would rather make the changes myself so as to help with my learning of the efi live system but any pointers and advice is more than welcomed. The truck has 3.42 gears and the rear tires are 235/75/15. I'm hoping to at least fire it up tomorrow, if not take it for a short drive. The engine and trans are stock with the exception of no catalytic converters and a cold air intake. I did remove the rear o2 sensors.

What did the engine/trans/PCM come from...?

[creekrat]

Appears to be a 2005 gmt800. I do have a return style fuel rails and drive by wire. The OS is 12592618. The tune is showing that it is a 4wd, although the trans is a 2wd variation. By reading the PCM it looks like the engine may have been a L59 but not sure how to tell for sure with what i have.

I looked and the injectors are pn 25317628 so it is not a flex fuel system, correct?

[joecar]

So the FPR is at the fuel rail and has the reference hose connected to manifold vacuum...?

With the ref hose temporarily disconnected, what does rail pressure measure...?

I don't know, I'll have to research it.

Haven't got that far yet. Have yet to start the truck. Just wanting to get stuff taken care of before the initial startup
