Best way to completely disable TC and ABS?
Its an early 98 C5 and I am concerned that the ECBM system has crapped out. This car is only used for autocrossing and I want to practice with no ABS and see how is does.
To completely disable TC and ABS should I simply pull a fuse? Which one?

My early 98 c5 does not have active handling. It does have traction control. And it is stuck in the on position. Been told that they think my ecbm is out but I am not sure. I can not race the car with this archaic TC system engaged. I need to disable it somehow. I would prefer to keep the ABS but it is not a requirement. If I pull the steering position sensor will it disengage the TC and leave the abs?

by unplugging the steering wheel position sensor on my C6Z it completely disables the active handling, and sets the TC to off by default.
i can turn TC back on with the button, but active handling is completly not even in the menu and disabled.
ABS still works.
its exactly what i wanted.

But this is an early model C5 and it doesn't have active handling. Just for the heck of it I bought another switch to see if that may fix this issue. If it doesn't then I have till Sunday to figure out how to disable everything.

Pulling the steering sensor on a C5 to kill traction control won't work. It still turns ON by default. I've had my steering sensor pulled since 2013 and have to remember to turn off the TC at the strip or during 1/2 mile passes.

The beauty of the early C5's is that disabling the ABS won't effect brake bias - the later C5's have dynamic rear proportioning integrated in the EBCM so disabling ABS also screws with brake bias. On your early car the bias still stays the same - so unplug the large maxi-fuses, I believe there are two of them - and you are ABS and TC free. If you are still unsure if it's truly disabled you can always unplug the EBCM as well, but the fuses will do the job.
If you're going to go on with no ABS you may think about some less aggressive pads - not sure what pads you are running but something with less initial bite will be easier to control.
Ideally try to find a pad that you have to darn near stand on the pedal to make the car lock up, it's not easy to feel lock up.

Depends on the tires, HP+ are not that grabby - it's not like you have DTC-70's on or anything. Just remember to ramp up the brake pressure - no stabbing!
Easier said than done on autocross - also you may decide to play with brake bias a bit - DRM sells an aftermarket spring to add more rear brake. Or you could install an aftermarket bias **** so you can fine tune it yourself. Wilwood has a couple and AP Racing has a really nice one. But you would have to be able to do some testing to get it right.

Pull ebcm? my stopped working ages ago so I just took it out. Never had any TC/AH/ABS and outside of the messages coming up each time telling to you "Service ...." there was no effect on the car. 02 Z06.

This may seem ridiculous but I may have some electrical gremlins and yesterday after a gas fill up, someone cut me off badly and I was angry... so I dropped the clutch and spun the rear tires and somehow the ABS came on.
Driving all the way to work, no ABS and when I braked, I was worried of lock up, but I actually braked better than with ABS functioning lol. My old track car (an older car) came with no ABS and so i was used to racing with no ABS but... on this very topic... makes me wonder... is the ABS interfering too much because of some issue and therefore I braked better with it unintentionally off...
