Anybody know why when I upgrade my stock file to a dsp5 my OS changes completely?
Stock is a 15228758
Upgrade to DSP5 and it changes it to 05875805
Won’t let me flash this. Says controller is locked but I can flash the 15228758 no problem.

the OS number change is a result of the DSP upgrade and is normal. the locked part I'm not sure about. have you tried checking the "try other unlock strategy" or whatever it's called? also, you are doing a full flash for the new DSP tune correct?

I know the number change is normal but IIRC on the LBZ it only changed the first digit to a 2 or 5 and the rest was the same. It wasn’t a full on random number change.
I tried alt keys. I’ll keep dickin here.

Got it to go third time round lol. Time to setup the CTS2 and see if this heap wails or not. I put a pretty rank single tune in it last year.

Well got the tune in but the CTS2 needs to be updated before we can switch tunes so I put the single tune back in. I’ll post that tune in here when I get my laptop charged up.

He massaged the lly firewall to fit in place of the stock ‘72 one. Full hvac and all. The cab is wider on the new trucks so it was a lot of hours to make it fit. Have to open the door to open/close the windows but small price to pay for a/c!!
Floor pan is still ‘72.

Naw. He might replace the rusted out rockers this winter and do some steering and front suspension repairs but other that he just hauls hay and cows around so it’s really just a work truck.
