From what I understand in general, cars with torque predicting algorithms use this data for the Electronic stability control activation and calibration.

Where the ESP measures the predicted engine torque output at the time and calibrates individual braking torque to compensate or reduce engine power to equalize the abhorrent movement of the vehicle

I'm not sure in what manner this is disabled but If it is FULLY disabled I am unsure to as whether or not it will effect the proper function of the stability control.

Since we don't have too many people running their cars off the road and reporting back to this forum, this seemingly transparent and benign deactivation of the torque monitor may have deeper consequences. The fact that some people that have torque monitors disabled receive a Message from the traction control that says "Check System" is a bit more discomforting.

Unless I can get a definitive answer to whether or not it will effect the efficiency of the ESP I will keep the Torque monitor ON.

The stability control still works perfectly fine with my Torque Monitor turned off. A quick drive on snow covered roads will show this. Get the tires spinning, reduction in power results. Get the car to slide around a corner, you feel the car slow down (brakes automatically applied) and a reduction in power.

As was said earlier, disabling the airflow and torque codes doesn't stop the ECU from still checking these tables for other functions.

Thats good to hear... if its just the CODE thats been disabled that would be fine... If its the actual system i would be worried.

People are getting the ASC light whether the codes are disabled or not, leading me to believe that it has nothing to do with the airflow tables. I don't think anyone really knows for sure when or why the stability control decides it needs to disable itself.

The couple of times I've ever popped the ASC light was with my airflow and torque codes still turned on.

I'm hoping Gunzo or any of the other guys deep into the Evo X's ECU will chime back in. I'd like to see what they have to say about the ASC light or the fact that with the codes disabled, there have been no limitations hit on dyno runs when keeping the airflow tables stock, or modifying them further.

bringing this back alive, so whats the exact fix for these issues. regarding diabling codes entering 0000 takes care of that?

Guys, can I ask you a question, how do you adjust torque limiters and airflow checks ?

I had a strange experience, I had DTC codes of, tuned a car (evo x manual), it showed 410 hp on the dyno, increased torque limiter and on the next dyno run the car showed 422 hp.

ok i believe i have found a solution for the car.

airlfowcheck tables increase by 40% above 100
airflowcheck old also double

increase airflow offset by double

disable torque monitor P1241

and your good to go

These settings won't work for everyone. They need to be specific to your setup.
