Wheel spin sensors on a 97? Unplugging for 1/4 mile runs
Hi guys, my 97 LeSabre has the same traction control and wheel spin elimination routines that the Series II Bonnevilles do. Even with traction control turned off, if you free spin the wheels the PCM aggressively pulls out timing so that you can't spin them until timing is put back in. I have an Intense Standard PCM in the car now, but I didn't opt for an extra $100 worth of tuning to eliminate the wheel spin timing cut routine (I probably should have). On the street, wheel spin isn't the biggest issue, but running the 1/4 mile it will be. I definitely don't want to spin and end up with the PCM pulling timing out on me. I've run lots of rear wheel drive high horsepower cars on street tires at the strip before. I know that street tires + rubber coating the track + water from water box makes it like you're launching on ice. If I disconnect the wheel spin sensors, I know this will not only eliminate the possibility of the PCM pulling out timing from wheel spin, but it will also disable ABS until they are reconnected. Pulling the wheel sensors won't throw an SES light right, just an ABS light? I finally got my TPS adjusted so it isn't throwing mysterious codes anymore, so I really don't want to throw an SES light messing with the wheel sensors, and then have to drive back over to an Autozone so I can clear the code (yeah I really need to get a scan tool).
