Finally success, that code is LSB, I wonder why I didn`t notice it so far.
bbmike, thanks for cooperation.

In the dump I have the cal area have correct checksum, but when I try to test the OS it always fails for some reason. Could it be a bad dump or some data missing. Found some update files for the ipc and the checksum are all correct there.

The only way to check is to flash update files and than make a dump.

Someone with ipc laying around want to make some dumps for testing?

Did some new full dump and at some point ipc was too slow to repsond and some messages were skipped in the log.

New log is a little better and have full dump, now checksum matches perfect.

Here is log +bin for analysis.

Also here is a script for dumping bin to log. It is set to read 0-30000, it will take roughly a 45 minutes with mdi in car, on bench it might be faster. Set with algo 12.

Nice to see you got it to read out correctly. I had to go back and learn to calculate the checksums again. I'm starting to get interested in messing with the clusters and updating IPChammer again. Thanks for the script to read the clusters. Do you have any info on how to write the scripts? like what all the different numbers mean? I have a few different modules that would be nice to read.

I looked into this and fixed it today. So it will work in the next version.

I have many IPCs for both full size GM trucks from 2000-2007 as well as clusters for the 2002-2007 Trailblazer/Envoys. I can help with testing if needed.

darkman5001, It will be great to get some files out of them.

Just hook them on bench with mdi and run the script with universal patcher. Save logs to a rtf files.

Just started playing with this software. Has any advancements been made to the capabilities lately? I would like to replace my "service airbag" message with a custom dic. Any thoughts of getting a read of the cluster and being able to edit my own file? Any advice or help with customizing my dic messages? 2004 silverado 1500, 05 cluster for 03-04, has steering wheel control and driver 1/2.

that should be easy enough. you don't need to read the cluster. ipc hammer should have the stock files to start with. Find your calibration file, search for the service airbag message and replace it with what you want it to say. save the file and write it to the cluster with ipchammer. I don't even think there's any checksum correction needed.

I am not finding my os or cal file. I will post the numbers whenever i get a chance. I was able to open the cal files in tunerpro and edit the hex successfully.

As far as I know, as it is a port of PCMHammer, it has no .bin files.
