I do the "double pump" while entering a brake zone with my right foot. Works well and scares the hell out of the GT3 behind you.

I honestly didn't realize that I was doing that until I started looking very closely at the data.

Interesting....

Why not practice modulating the throttle better instead?

What events do you do in your car? HPDE, Time Trials, Club Racing, etc...?

It was a surprise that there was that little grip at that point on the course (SCCA Solo). I didn't even realize that I was doing it until I looked closely at the acceleration data.

Just another reason that I prefer accelerometers over GPS for data acquisition.

Funny you mention this...GT3's (street version, not Cup) are drive-by-wire too, and some of the owners complain about the throttle cut-off while LFB too.

hey, anybody have the info on cutting the wire to the ecu that provides the brake on signal to the ECU that prevents the engine from running WOT?

I had that thread saved but now can't find it and need to mod a new car...
