I haven't used hptuners software in a while because truck has sat for 10 years. Now i want to start messing with it and with the newer software i have a few questions.
First is my last read from my ecm was back in version 2.24 and i see new option in the current software. Should i write truck back to stock and reread with newest software to poll more items or something like that or can i just read file thats in it and all information should come out properly.
Second i want to do segment swap on engine and engine diagnostics. I have all licenses and proper os files but not sure if i should write entire or just calibration.
Lastly just curious when you do a segment swap i assume it does more behind the scenes that just copy all adjustable setting over? It must make hardware logic changes like tell ecm to look for something that it didnt before of maybe activate unused pins like in 4l80e swap. I found in the forums that you cant just select 4l80e in the trans type you have to do segment swap for it to work. why would there be a trans type tab if it didnt do anything more than change label in tune?
I have a 2003 silverado v8 p59 ecm stock ecm
Thanks for you help.
