brake boosting: what function cuts power when brake pedal in engaged?

B_brems I believe is the variable. I see it in GGPED but it doesn't seem to matter unless you're in limp mode. I didn't look at it very much.

Anyone have insight?

Thanks,
Rey

Left foot braking

Set either of these to maximum to prevent throttle cut when left foot braking:

    NWPMBBR - Minimum RPM for acc pedal value lockout on brake operation
    VWPMBBR - Minimum speed for acc pedal value lockout on brake operation

I can confirm that this is correct as I have done this before  Wink

brake boosting was instrumental in my HPX maf part throttle fueling adjustments. With some skill you can keep your engine at constant RPMs while loading it more and more... not friendly on the brakes but my zimmermans+akebonos survived just fine Smiley

one suggestion, set the speed threshhold to something like 120 instead of max, then in an oh shit runaway situation you can still have brake kill throttle

Once you start hitting boost, your pedal gets harder and it starts to lose grip. I've done it in a few 1.8T's and it gets hard once that happens.
