Default Real Time Tuning in HPTuners ?

Not able to find the "Button" to enable RTT in my HPTuners program.

Check the availability for your pcm. Some don't have the ability to run 2bar and RTT. Also, make sure you are running the latest version, or a really old version of HPT. When they first did the last huge update, they left out RTT entirely. Subsequent minor updates brought it back.

^ yep you gotta have 3.2 or newer.

go into the editor and select Engine>General>Real Time Tuning and then select which parameter you'd like to tune

then go into the scanner and connect to the vehicle, a little lightning bolt on a wrench icon pops up and you can access the tables there. they are numbered 1, 2, 3 etc...

I completely forgot to mention that you have to write entire an RTT enhancement to your vehicle OS before using RTT.

If one does a "Write Entire" with a 2BAR OS will RTT then become possible ?
.
Is it possibly the case that I first did my 2 BAR OS upgrade, 6 weeks ago while running an early 3.0 version of HPTuners, and then, after the latest upgrade to a 3.2 version I have a non-enabled RTT function, hidden, and need to perform a " Write Entire " of my LATEST TUNE in order to make the RTT function activate ?

If available for your vehicle, 2bar RTT will be one of the enhanced options. If you used one of the first versions of 3.0, they had not re-enabled any RTT yet.
