In the process of putting an '02 6.0 in my friends 96 k1500. I have on hand an '02 express 2WD van ECM for a 5.7. I am hoping i can convert this ECM to a '02 6.0 4WD Silverado ECM. So far i've figured out the Vin # change will change the labeling in the description box and the segment swapper tool should hopefully get all of the right tables swapped over. However i have a few more questions before i feel confident in buying the credits for the Express ECM and making all the changes. Hoping somebody out there knows and is willing to help:
1.) The express van is a GMT 610 and the silverado would be an 800, can i simply change the Platform drop down box in the system tab and that would be sufficent?
2.) The express van is a 4x crank signal and of course the 6.0 will be 24x. Can i just change the System Options Matrix -> Crank Low Res to a 0 to make this change. It's currently a 1 in the express van table.
3.) Are there any 4wd segments? My friends truck will be a manual, but it does have some 4wd control associated with the ECM, are they any segment or changes to the ECM i need to be aware of?
Answer what you can if you don't know all of them.
Worst case is i'll drop $100 at the dealer to have the entire VIN and OS flashed on this ECM. But i was hoping to save that $ and just use what i have.
