Perhaps you should read a little more around here. Those were all English words and if you want to learn how to tune your PCM for free, your vocabulary needs to come up a little.

English is good my friend. I have a vocabulary. Thanks. Just didn't understand all he had said. That's the point of coming here right?

Sure, that is the point of coming here. And we like to assist people in solving their EFI problems and getting their vehicles up and running. But so MANY show up here wanting a difficult topic such as this served up to them in one email to make it easy for them. And tuning is NEVER going to be learned that way without more effort.

I've been reading. Not looking for a hand out. Was looking for correct XDF as that's what I read I needed. I know how to do most of the other stuff once I'm in. Assumed that's all I needed. From what I've gathered this far. Also was looking to see if there was an xdf that was close, I've seen others suggest other SNs that would work.

I'm not aware that an XDF has ever been created for that particular OS - XDF files are very hard to create. Your later 2006 OS, engine and transmission combination will require a 1 megabyte PCM OS and there is only one good, richly featured XDF for that OS - last four digits of the OS = 7603. You will be overwriting your 12613248 OS with xxxx7603 after editing 7603 with its mated and married 7603 XDF using the Tuner Pro RT editing app.
Do you have a bench harness with at least two amps of 13.8 VDC support?
What tool will you be using to perform the writing to the PCM? I like LS Droid and PCM Hammer but have dabbled with Universal Patcher to fix self inflicted checksum errors - not to write the file to the PCM.

I didn't think I needed a bench tester I had contemplated doing it, but I'm just using it in vehicle with PCM Hammer, I unplugged most of my other module relays. I read a few guys doing it in vehicle, now correct me if I'm wrong is that not a positive way to do it? I watched a few vids "FixedUntilBroken" on YouTube, he said you can do it in vehicle unless doing multiple is why most people use bench, and I had it hooked to a battery charger while loading it, and I keep it on 14v, and I believe lowest setting was 4amps.
yes it was for no vats for engine swap into a vehicle that didnt have a ls. if switching to a 7603 os (operating system) you will need a new eletric foot pedal and module. 2006 is different for the os you have. truck will not responde well. may need to swap something with throttle body or injectors to match the 7603 os. 7603 is the only xdf i know of for the p59 pcm 1mb memory.
