I havnt. I went to the complete 04zo6 os. My car is on jackstands getting a bunch of upgrades including a new motor so it will be a couple of months before it gets driven. Honestly even if the flex fuel dont work it was worth upgrading to the p59 because the car idles much smoother. I guess the p59 can handle a big cam better because it is faster.

This is correct. No segment swaps at all. I mapped out the "hidden" parameters in binary to edit the parameters that we do not have access to.

So im assuming this has been done using the user defined parameters hp tuners has but I have no idea how to do that stuff and i can not find a good write up on how its used yet. I will figure this out lol. Im not trying to make any money off this but I can completely understand why a tuning shop would not want to give this info out. I just want a flex fuel C5 lol.

Yes user defined parameters.
You'd be surprised how many parameters, switches and tables we do not have access to still. I've spent the last few years populating tables myself as I ran across a scenario I needed to edit those things.
With that said we have opened this up to purchase a Flex enabled tune file for any of the Gen3 applications that aren't easy to simply segment swap. This being any of the C5's and 04-05 CTS-V's or even 2004 GTO's.

Wow, I've been trying to run this down and the information around this is so confusing and noisy.
I've got a 2004 C5 Corvette with the P59 PCM. Soooo looking to do flex fuel. So you can do a flex fuel tune on this via a mail order tune? I'm assuming this works similar to how tuners do remote tuning using the EFLive AutoCal. Although I currently have the latest Pro version of HPT.

A friend of mine brought a 2002 Corvette by the other day and wanted flex fuel. Having done C6s and 411s in the past, I was very surprised to find that simply enabling the feature didn't work.
I was able to get this running, but those options were not available in HPT. I see this is a big secret as it turns out, but in all honestly. It was just several tables that had to be turned on. Like sensor slope, spark blend factor and a few other "delay" related constants. Using a P59 and 2004 C5 file of course, and had to swap alternator terminal F pin. Since the car is speed density, I just moved the MAF wire over to pin 56, reusing existing MAF harness for the flex sensor.

Added custom tables in HPT to make the c5 file work -
try turning add blocker off for this website if you have issues seeing them. you can test it by allowing a temporary pause on the page and refreshing it.
