I didn't make this port but I didn't see him posting here so I figured I would share it with you.
One of the viewers of my channel ported PCM hammer to work with Instrument clusters. It works great but still a work in progress.
I just figured I would share it here since you guys made PCM hammer and that y'all would like to see what he made.

Github: https://github.com/mikebb203/IPC-Hammer
Video I made: https://youtu.be/-WyhoHrp2uo

Edit: BTW if you have questions on using I can help I also know how the cluster works but I can't really help with the programming side I am only good with embedded stuff not PC programming

Can this do anything a tech2 cant?

Wow, that's really cool!

Hello, and thanks for sharing. I'll pick up an instrument cluster to play with. Where would I pick up the calibration files? How would I find out how to connect to the cluster? Is there editing information to study?
Thanks

This is kind of neat, I had to play with the code to get the only elm327 I could find at the house to run, lol.. changing mileage was unbelievably easy.. Too easy really.. I have no real use for this but hats off and very neat to see!!

Cal/os are both on the mcu. not to confuse you but the mileage, unlock key and some of the features are on the eeprom. IPC hammer supports writing to the eeprom also.

Edit oh you meant the cal files in general well all the ones that exist from gm are included in the github. They were tactfully acquired.

The os/cal have no checksums that I know of. I haven't played with the os too much but in the cal you can change the text. Like change it from driver 1/ driver 2 to fucker 1/ fucker 2 lol.

This is really cool, can you do a video reading out the millage chip? And can you read the bin out of the cluster or only write to it? Can I use it for a 04-07 colorado cluster? it is class 2 VPW, as well.

It doesn't do dumps its really for writing. he has only been working on gmt800 so far just because that's where the demand is at right now.

There are checksums for both the OS and the calibration. The program has a button for testing the checksums. It shows what the current checksum in the file is and what it should be. A future update that I want to add is the option to update the checksum.

Can this be used in vehicle or is a bench harness required?
