0411 tuning in tunerpro

NSFW I will ask him, I know i already downloaded the PCMHammer form there. One question he had was where to locate the bootloader. im looking at the raw code from the bdm, still rapping my head around stuff. and just comparing bins in tunerpro I've noticed that the 8322 os and 5074 os with the cos3 xdf match a lot beside the things you would expect to very ve tables, timing, and maf, because my 8322 is calibrated to a 6.0 and the 5074 is a 5.7.

But anyway i can help i will i would have never been able to flash my truck without guys like you and peteS.

If you mean the bootloader in the binary file you got from the BDM... The first four bytes are the initial stack pointer, and the next four bytes are where executions starts. Jump to that address in IDA and press C to start disassembling.

Or go here for a head start with a P01 operating system:
https://github.com/LegacyNsfw/12593358

Or here for P59, but I've barely even started on this one:
https://github.com/LegacyNsfw/12592425

But if you mean the kernel that the app uses to reflash, it's not open source yet. Long story. It will be eventually though.

Ok thanks. I have the 68 disassembler downloaded but never used it. And I'm patiently wait for your flash kennel. Thanks for the links too. I'll check them out and if I get some custom o.s.'s going I'll let you know.

Would someone with more knowledge of binsCOS3.bin COS 3 - 1290003 - 512Kb PCM - based on 12225074 - 2001 to 2004 Holden model years (1).xdf look at this xdf and bin C.O.S 3? i think its missing the calibration, but im not trusting my judgement yet.
