Would the below products work on our MCS when we go over the 18psi to trigger off the map sensor/ecu to light up the traction control light to lit permanently?

brings up a familiar sequence conundrum:

you stomp on it, spinning the tires and lighting up the traction light, boost builds to >11psi, the DSC devil cuts the throttle as you plant your nose in the wheel.

I turn off any traction control as I turn on the ignition (and will automate this soon, reversing the default condition)

how would those other gizmos work?

 

I guess this problem is more directed towards individuals who has the pulley upgrade to either the 17, 19, or even the 15% depending of climate condition. even without wheel spin, i was still overboosting >@18 during weather temperatures of 25F and below. As I am planning to upgrade to 19% with GIAC and larger injectors, I wante to see if we can take preventive measures to eliminate the triggering of the map sensor to light up the traction control light.

 

nyminime, I've had my traction control light stay on with the 15% pulley once on a top speed run and once with the 19% pulley on a top speed run. During normal heavy foot spirited driving the traction control light staying on has not been an issue. Turning the car off seems to reset it, as I start the car again the light is off. I had no idea overboosting was causing this light to stay on, thanx.

 

Why don't you just use Ian Cull's "Track Mode" switch?

 

I wasn't aware that high MAP would trigger the traction control light, separate from wheelspin; is that what you are saying, NYMINIME?

 

Yes - when you hit 18lbs of boost or higher, the DSC light comes on and stays on until you restart.

 

So is the 18psi/dsc light correlation a function of lack of headroom in the MAP sensor, or lack of a multiplier in the ECU mapping?

What are El Diabolito and the other twincharged guys doing for MAP and mapping to overcome this?

 

I was always under the impression that the TMAP sensor had a 18psi upper limit. As is the case with solid-state sensors, I am not sure whether this is a 'hard' limit (increase in pressure beyond 18psi results in no change in the output signal), a 'linearity'' limit (increase pressure results in increasing output, but in a decreasing factor compared with pressure), or a 'failure' limit (pressures beyond the design limit result in damage or calibration drift of the sensor (not likely in this case)). One would think that if the limit were reached, the ECU would throw a code and light the MIL rather than the traction light.

Since installing the pulley in my car, I have noticed a change in the behavior of the DSC/traction control of the car. Where before the slightest spin of a tire during acceleration would result in bog city and a face plant into the steering wheel when the DSC would engage, now it seems the car is still scratching at the pavement or outright losing traction at WOT with the light flashing away. A quick shift into second (or sometimes even third now ) and a stab at the gas will pop the light on with no real bog as before.

I aint complaining, but I'm just sayin'...
