I make a lot of search and the only thing I found is the RTT topic to ask HPT to make the RTT
actually does the RTT works on J body, but I didn't find how to make it work if it's possible
if you have an ls1 you can do it, but its unlikely this will come to any Alpha N pcm anytime soon.

Alpha-N = "throttle position vs rpm" tuning. Almost all J-body PCMs run Alpha-N.

Soon??
Actually never.
Its a hardware question. Some of the newest PCMs can do it, but they are built to do it. Its a pre-curser to OBD3 where the automakers could be required to automatically do updates via satellite while the car is running.
In order to do real time tuning, the PCM needs to have 2 memory chips and the hardware to switch between them between clock cycles.
Changes are saved to the idle chip and the PCM switches to it at the start of the next read cycle. The next change is saved to the previous chip then it switches back, and so on, and so on.
