I feel your pain!!! Here is how someone explained it to me.

Pressed full throttle.
Turned ESC on.
Held full throttle until the ESC beeped 3 times.
Pushed full reverse until the ESC beeped once.
Moved to neutral until the ESC beeped 2 times.
Pushed full reverse once (set paramater 1 to "CAR Mode"), moved to neutral.
Full throttle, moved to neutral.
Turned ESC off.

Now that is basic car mode setup. If you want faster accelleration the do this. Instead of turning off the controller do this after the final step.

-full throttle (unless you want to adjust the strength of the brakes)
-hit reverse 1-8 times (and let it do its succession of 1 beep, then dual beeps after each time you hit reverse), with 1 giving the fastest acceleration, 8 giving the slowest, with 4 giving you the same acceleration you have now. If you want the fastest acceleration, only hit reverse once.
-Hit full throttle to accept this setting.
You can turn it off now.


I hope this helps.
