Bringing old thread up. Im wanting to change the remote start timer in my 2008 suburban. What is the cheapest tool to be able to read the .bin from the bcm?

Can either built a file from the sps files complete enough to flash the calibrations or you can read it using mode 23 and a J2534 device..
If you post up or pm your vin I can see if I have the files and I wrote some code to build a bin from the cache files.. That'll let you play at least..

Here's your files straight from the cache.
Here's your files after unpacking them.
Here's your files put together into a bin..
What kind of runtime were you looking to get? Timer is in the System segment..

I was just trying to change it to 20 mins run time.

ok, I found the section of the OS that describes the segment addresses...it's just formatted differently than I'm used to. Ghidra and ida are showing what looks to be valid data so it's a step in the right direction. I've narrowed down what I think are the the staus bytes for the remote start enable and possibly the hood switch dtcs...maybe. I've been assuming that the timer setting would be in the "powertrain control" segment but can't figure anything out from there. Maybe I'm incorrectly assume that the timer value is in that segment. I'll keep at it and update if I figure it out.
Can I ask what you used for hardware and software to pull a complete BCM file?

Hey team,
Hopefully you don't mind me reviving an old thread (I did see that it's only 5 or so down from the top, though).
I can't get Ghidra to load in another processor/language. The 2013 is using that Fujitsu MP91 isn't it?
I can't get either that 2008 BCM bin or 2013 BCM to start decompiling correctly, or at all. Hoping someone here can help

look on page 10 for the fujitsu files you need. add them to the ghidra processor folder
