Thanks everyone. I don't have a HPT license, but would want to keep the same numbers anyhow. I will give this a try.

Hello, I see this is an OLD thread, but can you still view tunes in HPTuners for free? It says you need to have an account to get into the repository. Also, would this process work to do mild changes to a tune in TunerPro? I have a 2001 Corvette, and am adding long tubes over the winter.aaronc7 wrote:Yeah, development has really been focused around a single OS for the 512K P01s- 12212156. It's an OS that supports all possible hardware combinations etc., so it was logical to go after it first. It was also used in 2001-2002ish vettes, so you can definitely make it work.
This is what I would probably do: Download and set up EFILive or hptuners on your machine (both you can install and view tune files for free). Find a stock 2000 C5 Manual tune running same OS you're on, and find a 2002 C5 manual tune on the 12212156 OS. Now you have a reference for what your stock tune is....
On Tunerpro, Open up a 2002 C5 manual 12212156 bin file, import proper XDF. Now you can reconstruct your stock 2000 tune file in Tunerpro, using hpt or efi as reference. They will probably be pretty similar, but there were some minor engine changes and such over the years, so might as well identify all differences and copy them over to start.
Then PCM hammer you would do a "full write" with newly created/modified 12212156 bin file.
BTW I also opened up your posted stock tune file, tried a few random 512K XDFs and they were all clearly a mismatch. Seems like an oddball OS, so not really useable on the open source front until something develops it (if ever, since it's rare).
