ABS cutting engine power.. able to tune out?

[Wile E. Coyote]

Something I've noticed while driving the gold car (1996 Tbird LX, SVO supercharged) around is if I cut a corner sharp, the ABS light turns on and, in turn, cuts ignition. When the light goes out, ignition comes back but it takes a second to clear out the excess fuel it dumped.


Is there a way I can tune this out, or is there an underlying problem?

There is no connection between ABS and the EEC, nor should the ABS be operating unless you’re braking, nor is the light supposed to illuminate when it is operating.

The ABS light indicates a fault, and if you have ignition cutting out in addition to its illuminating while cornering hard I’d check for a loose ground somewhere.

Since you know the circuits in these cars, is there a specific place you would look? Like the ground junctions in the kick panels or somewhere in the engine bay?

I’d have to look in my EVTM later but I’d actually be looking at the grounds around the core support since ignition ABS and others ground there, where the kick panel ground is mostly just EEC

Using any Mark 8 parts? "
Yes, for later models of the Lincoln Mark VIII, the ABS system was integrated with the engine's electronic torque management, which is part of the traction control system.

While basic ABS (Anti-lock Braking System) primarily works by rapidly modulating brake pressure to prevent wheel lock-up, more advanced systems, especially when combined with traction control, can also influence engine output to prevent wheel spin during acceleration or under braking.

Specifically, a forum post indicates that "On 1997-1998 the ABS action is integrated with electronic engine torque management for Traction Control." This suggests that if the ABS detected wheel slip during braking, and the vehicle also had traction control, the engine's throttle (or torque output) could be affected to help maintain control."

Correct, the 97/98 Marks had a much more advanced version of traction control which linked the PCM to the ABS computer to modulate the brakes in conjunction with a dramatic reduction in timing to control wheelspin. It is operable at all vehicle speeds. It is always enabled by default upon startup, though it can be disabled by the driver via the information center or in a tune.

The traction assist found on the MN12 is an ABS-computer-aware only modulation of the rear brakes when wheelspin is detected, and is only marginally effective up to about 30 MPH.
