I got tired of waiting for superchips and DS to come up with software to tune our trucks so I uploaded the pcm software and was able to crack the code myself and spent about 4 hrs rewriting the abk and setup a backup and now have disabled the MSD, changed the top speed limiter, changed the shift points and was able to adjust air and fuel mixtures. Increase in power appears to be significant it now does not shut down over 100 mph and no need in having to run the truck in 5th to disable the MSD. I will run this new code for a few days and pull the plugs and see how they look. OBTW my truck is the 2011 R/T

Well if you really got it figured out where large companies failed maybe you oughtta pick a company and sell this to them so the rest of us can use our trucks with the training wheels off too.

Breaking there source code took some time but once I hacked into it the codes were easily writeable and were able to save anyone with knowledge of DOS and ABK can do the tune with the open code file, a laptop and harness to the PCM cnnection along with a laptop is all one needs. You will need to use superuser to keep the open source code usable for other tunes. You also need some working knowledge of how to use Cyangenmod.

If any of the big companies would be willing to pay me for this info I'd be happy to hand over to them the open source file I have created, the thing is though and from dealing with other sources in codes and writing code they just don't want to pay for the source files. DS has already contacted me for my backup and source file so lets see if there heart or shall say there money is in the right place.

Why would something so new and complex have anything to do with DOS? I am super intrigued however, how were you able to send the requests to the PCM to allow it to be read?

Which OBD setup did you use to interface the PC to the port?
Also, what software did you use to pull the info from the PCM, then compile it?
How hard was the encryption to hack?
Sorry for all the questions, but again I am super intrigued..

DOS is used to rewrite the code but in order to hack the code I had to use a program called Cyangenmod, I pulled all the software from the PCM onto the laptop where as the progrom broke the encryption and transfered into DOS and rewrote my own program. Saved both files and then sent back thru Cyangenmod so it then enycrypted the rewritten program and installed back into the PCM.

Now that I have the saved original file I'm going to play around with it in Excell and see if by any chance I can rewrite the codes there. If this can happen then it makes life so much easier to many than going over into DOS

Sadly I don't get how or why a nobody as myself that has access to writing codes and a computer can figure this out yet high paid engineers are stumped.

Anyhow I will pull plugs on the truck this upcoming weekend and see how they look and see what else I can do with fuel and air mixture and the timing to push it just a bit more.

22Dasher, are you a software engineer or something by profession? That just seems crazy that you were able to do it and the dozens of engineers couldn't...

If you did do it, why not start your own company....overnight millionaire...?
