    Left-Foot Braking Causing "Limp Mode?"

    I had this happen to me a few times. Anyone else had this happen?

    Well after doing some reading I see that the sensors are set up to do that. But why is that? Having full boost out of a corner is beneficial for a laggy car like our abarth but it seems that won't be possible

    Does limp mode kick in right as you are hoping for power? Meaning... does it offset the suspension when you aren't expecting it and feel unsafe? There is another thread on here in the Racing section...someone else is successfully using LFB at autocross... wondering if turning traction control off all the way allows for more LFB before limp mode engages? I forget the trick...

    Does it do this with the ESC fully off too?

    Hell I'll probably be faster around the cones in limp-mode than under boost anyways... still going to find some road time somewhere to practice this before the next event.

    You have to hold the brake for 2 seconds to engage the Brake/Throttle Override. So, if you can keep your left-foot braking below two seconds each time, you should be okay.
