Hi To ALL, great forum and great hints on tuning. I plugged the predator into the H2 today and just watched the real time data as I drove about town. Quite amazing. The O2 sensors at normal throttle were 750 to 850 in 106% weather. I haven't flashed in the tune they for the H2 as yet. I was wondering if in the options mode, we can do the optional tuning allowed by the device as the engine is running? That would be great to actually feel the shift's changing etc. Does anyone know if that is ok to do with the predator.

 

I donot have a predator but I would tend to think no...I believe that when you tune or make changes with the predator it is "Flashing," the eprom/chip/ in the pcm so just as with any other computer when you are upgrading or Flashing you would not want it to be disturbed in any way.

 

Hi Doc, thanks for your input. You are most likely correct in your thinking. Wouldn't it be nice if we could for dyno work. i will let you know how the predator works ith the Hummer.
