I've dynoed a million times and understand the deal with the ABS and BRAKE lights coming on and staying on for 300 or so miles after dynoing, but recently I've had to make 2 quick stops - not panic stops, just hard fast stops and I got wheel lock.

I've never had that happen to me before even after dynoing with the ABS/BRAKE lights on, but then again I might not have ever needed to brake really hard on the street during that period right after dynoing.

Just wondering if that's ever been the case with anyone after dynoing.

BTW, I know my ABS used to work just fine. As a temporary setup, I am running a different type of front tire from my rear and also a different type of brake pad up front from my rear (matching them next week) - but all that did was make ABS kick in sooner. Now it doesn't seem to work at all after dynoing with the ABS/BRAKE lights on


Oh, and I did disable VDC via the plug behind the shifter and has been that way for over 2 years now and have always had ABS

 

Well, if the lights are on, then ABS is disabled. When the system returns to normal and the lights go out, it'll start working again. You could prob do an ECU reset to get it back right away (not sure, though).

Why does the ABS system freak out and disable when dyno-ing? This is the first I've heard of that phenomenon.

 

yeah I hope it comes back - that was my first thought, but wow, not having ABS sucks

it freaks out because the front wheels are not turning, but the rears are turning, so the computer doesn't know what to do and thinks theres something wrong

 

Ah, ok. Odd that it takes so long to come back online...
