Inexpensive Opensource Flashing(Read is 100% working)
I agree that I won't be able to use it. Now I need a good Bin file. Engine is a 4.8 with headers and an LS1 intake and throttle body. Pistons are flat top, so compression may be a little higher than stock. Not sure about the cam, but has trunions installed on the rockers. I am looking for a good starting point with an OS that has a detailed XDF available. Any suggestions?

What transmission? I have several BINS here with richly featured XDF files for 5.3 L engines and 4L60E transmissions. A 4.8 L engine is tougher for me to assist you but perhaps not impossible.

Next steps. I have downloaded 12212156 and a working XDF file. I have a used 09354896. I will use PCM Hammer to upload and save the Bin that is on the PCM. I would like to defeat the security and test run the engine. The bin I downloaded is for a 2002 5.3 truck. The engine is a 4.8 with LS1 intake. I will use TunerPro to modify the Bin and write it back to the PCM with PCM Hammer. This will be the first time I am doing this. Any comments or warnings will be appreciated.
I re-read the PCM and now PCM Hammer says it is good. In the last upload it showed as bad. Start End Stored Needed Verdict Segment Name

The OS number still comes out wrong in TunerPro. I guess I had a data error when I read it the first time. since the OS number is invalid, I remain unable to find an XDF file.

The OS number is the same in PCMHammer. 1273010 I found a reference to it on the HPTuners website So it is valid. I will try to read it with a friends HPTuner system. If anyone has an XDF that will work with this, it would solve my problem. Right now I am starting over with a .5.3 file and trying to get it working with 36lb injectors etc.

I wonder if that oddball numbered OS is a custom operating system for 2-bar or 3-bar that somebody squirted into your PCM? Custom maybe from HP Tuners or EFI Live . . .????

HPTuners shows it as a 1 bar OS, but seems to have 2 and 3 bar versions. I want to read the injector tables to get a good starting point for modifying a stock BIn. I currently have a
