89911, Thats why the "off" sw is great (but the PSM will temporarily turn back on when you hit the brakes - and goes right back off when you release)
Doug, you would love PSM in comparison. The TC on pre e-gas cars ,like the 99 996, pull power by goofing w/ the ignition and fuel maps. The e-gas PSM cars actually remove the throttle. It was POURING at Roebling and I was volunteered to drive both sessions (@ 1 Lap) - no WAY I wanted to drive someone elses car w/o TC on. Well, turn 1 on the warmup lap showed how futile that was. Coming out of the turn, the TC starts to intervene, I gently put my foot to the floor to let the computer launch the car, and the car continues to "fart" all the way to the next braking zone. I immediately turned TC off, quickly learned to drive it in the wet for the rest of the lap, and had the most worrisome drive of my life
I did really well overall, but I wish we could see my hands in the onboard video - I was on the edge everywhere but the camera makes me look smooth as silk. Spinning the tires across the puddles @ 100mph+ on the front straight wasn't fun either, but I didn't lift. An NSX wasn't so lucky and went around several times (but amazingly didn't hit a thing).
BTW, the TC had the same problem at every dry track too (but I was praying for it to work better in the rain). To its defense, we practiced w/ the car @ VIR on RA1s and it did a much better job. On R-compounds, there is enough grip for the system to eventually turn off. W/ even a great street tire it was hopeless.
