Yes it should be. Just make sure you grab the checksum dll from one of Phoenix's posts and put it in the correct location.

Tried to feed it to HPtuners
No luck

xdf is for tunerpro, not hptuners.

Guy at hpt forum was suggested to use this file
"I loaded that .XDF into my user defined parameters in hptuners, and now I have the table to adjust!"
Looks like something was changed since )

Well they do seem to have a guide here https://files.hptuners.com/help/UserDef ... meters.pdf but I don't know how much help you'll get here. You probably should ask hptuners support since the functionality is in their commercial software. Or, use a low cost interface with the free tools to do the same job and use tunerpro or universal patcher outright.

HPT create user friendly interface and real time tuning patch inside standard PCM without hardware mods but locked important parameters
TunerPRO and UP much more capable but I cant switch them to metric

I would not feed it the whole XDF. I would create a new XDF and copy over the parameters you want to use with HPT.

Never done it before
Is there any tutorial ?
HP tuners plays with me
Now I only changes gears speed and 3sec torque reduction returns back out of blue (I didnt change any parameter related to engine or tranny torque)
HPT changing something but not shows it in available to redacting area
Looks like I will be forced to use UP nevertheless I hate imperial and don't know how to switch units to metric

Well, scientifically, traction is only affected by torque at axle, not engine. I suspect code follows same logic.
So changing axle ratio would matter.

does anyone have any advise for making changes with this OS when adding long tube headers? I've found a couple parameters that seem related but if anyone has experimented first hand let me know.
