Well I couldn't stand the car just sitting there so before this "blizzard" we are supposedly getting hits I went for a spin.

I had not taken it out in almost two weeks since getting it home and it does have the IPD ECU installed but not exhaust (yet)

I had traction control on and on many standing starts and first low speed 2nd gear situations I romped on the thing and it spun alot before a little grip. Only when it hit next gear it spun more before catching it.

Now the ground was moist and cold...

I'm new to traction control so help me out here - is it not going to work if motor is in boost or higher rpm???

where can I read about the traction control programming???

TIA~

Hello,

TRACS traction control system is very easy to defeat on 850 models with turbocharging. The main reason is because TRACS does not have the ability to monitor engine RPM's, thereby it cannot reduce engine speed/torque. Therefore its only form of action is by using ABS wheel sensors. TRACS was designed as an aid when starting/driving off if one of the drive wheels has poor traction due to weather conditions or the road surface and is connected to the ABS control module.

TRACS engages automatically at speeds below 25 mph (40 km/h) when one of the drive wheels loses traction. It disengages automatically when speed exceeds 25 mph (40 km/h). The sound which can be heard when the system is operating comes from the ABS system.

As you already know,TRACS can be disengaged manually using the switch on the dashboard. The indicator light will come on.

One really nice feature of TRACS is that when the brakes overheat, the TRACS light will come on. When the brakes go back to normal operating temperature, the warning light will turn off.

I hope this helps!
