[BiturboS4] left-foot braking & fuel (???) cutoff

The only way to left foot brake is to lift off, apply brake then back on
throttle.  Kind of a PITA.

First of all - I'm not member of this mailgroup - so please include me

I tried to search through many mailinglist about left-foot braking issue
there was no success to my specific problem... and my problem is that
when I
apply breaks with left foot while NOT releasing gas pedal there seems to
something like fuel cut-off by ECU... I installed on my S4'00 similar
known from earlier quattros (had it on my B4'94, S4'94 and now have it
also on
my CQ'87) to switch off ABS and ESP but switching off these features
disable this fuel-cutoff feature/bug ...

Does anybody have solution to this problem? I understand that audi
have built this "feature" to save the transmission from excessive force
sometimes I still want to use my left foot on ice track or on snow or in
condition ...

One thing which I was thinking is maybe to put some additional switch
ABS-aus) on wire from break pedal to ECU (at least I think I found one!)
but I'm
not sure does it help and I'm bit afraid also about possibility to
damage ECU...

thanks in advance!
