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.
from cache.zip
(195.02 KiB) Downloaded 151 times
Here's your files after unpacking them.
Decompressed.zip

Here's your files put together into a bin..

What kind of runtime were you looking to get? Timer is in the System segment..

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?
