I have a 2001 Z06 with traction control and active handeling. What happens when it is left on and dynoed? Any problems?

Did you have it on when you dynoed last?

With it on the engine will not rev and the drive wheels will barely turn, just turn it off.

Here is a post I made on another board.

Is there a problem with dynoing with tc and ah enabled? The reason I ask is yesterday I went to the dyno and did not disable them. The torque seems a little low.

This is with a cam and LT's.




I checked in HP Tuners, and under the Torque Management tab the Max torque is set at 350ft-lbs. It is electronic throttle control limited.

Here is the explanation from HPT help files.

Max Torque: Maximum allowed engine torque for Electronic Throttle Control fitted vehicles. This value is also used to control a torque based PCM output, this is used on some Holden vehicles to reduce Fuel Pump voltage when torque is below this value. WARNING: increasing this value on those vehicles will result in reduced fuel pressure, lean conditions and possible engine damage during high torque operation.

For clarification I own a 2001 Z06.

You can damage the traction control system by leaving it on while dynoing. The rollers usually spin at different speeds and confuses the electronics.

It was a single roller dynojet.

The car would not be able to make a dyno pull if the TC/AH is enabled.

They turned it off and your dyno is correct..

Just had an idea and went to pull the codes from the car. Comes back with c1221, c1222, and c1248. All history. It would seem that the 21 and 22 are from the front wheels not turning on the dyno, then the 48 when the system was disabled internally. So, it did make the pull with TC/AH enabled. I remember him having some trouble getting it sarted rolling. I guess this is why.

What he said. If you do not turn it off, the car will not spin on the rollers. Just hit it once and turn AH and TC off. Then pull the codes off the DIC and clear them. This is normal Good luck
