Hi,

just got my ScanGauge yesterday, and I have been playing a little with it.

I am trying to find a good indicator for how much throttle I can give without the AT releasing the torque converter. I have tried TPS (shows anywhere between 30 to 45 when the lock-up releases, depending on speed, I guess), LOD (about the same as TPS, but a little lower numbers), and MAP (always somewhere around 95-98 kPa as far as I have seen)

It seems that the MAP is the most accurate one so far, but I'm not certain that this is correct. What if I'm at a high altitude in bad weather? I guess the atmospheric pressure could go far below 95 kPa then (as 101.3 kPa is standard atmospheric pressure at sea level), and I think it still would release

Any ideas/thoughts?
