What the heezy is that?

Does that have to do with the TCS system???

Also, if you opt to have the fans stay on after the car has been turned off, does this occur everytime, or only when the vehilce is turned off when its at higher engine temps???

TM is not TC. And TM must die.
I've never checked if the fan stays on after running the car for a short amount of time. I'll let the experts answer that.

If one chooses to have the fan run on with key off, the engine coolant temperature must be above XXX degrees. If one just drove down the block with a cold engine and shut the car off, the fan will not run after the key is off.

One example would be running the car hard at the track, pull in the pits and the engine will cool the engine down more quickly to a reasonable level.

If one wanted to reflash one's PCM for the 3rd time, would one need to email one and make arrangements for said reflash. One misses the tuned PCM very much and one would like to get it back now that one is most likely done with dealer visits for the time being. And BTW Rick, you're still number one in my book.

Buy a second PCM already....

Earliest opening in the PCM world is October 24-25; booked until then. :crowded:

Its important whoever does the TM adjustment not remove it altogether. I don't know how Rick tunes but its advised to throttle the threshhold up across the RPM band at a fixed percentage.

I removed TM on my Z06 when it was stock. I nearly killed myself on the track when the car was unable to correct itself via active handling on a 90+MPH turn.

Back in the pits I put TM back into place and recreated the same instince over and over and did not have a problem.

IMO TM is not only a function of driveline preservation but is also connected through the vehicles stability control.

FWIW the condition was oversteer (back end coming around) I had on the track during the incident.

Should it be removed? NO

Should it be raised? YES

StealthV's tune are da bomb, which is why there's a line!

Now, Stealth's secrets are just that, secrets. I'm just a happy customer. If I had to hazard a guess about TM, I would guess that Cadillac played with throttle opening/closing rates, timing, and maybe even fuel, to reduce the torque output in certain low rpm/high load conditions.

After the tune, the car is much more responsive when you go to wide open throttle at lower rpm, you end up not having to downshift as much.

Down with TM! Up with StealthV tunes!

FWIW, the back end coming around is called oversteer.

Also commonly referred to as an "aw shit" or a "this is going to hurt" depending on where you are.

Also used to correct understeer. Giv'er Some Gas.

Usually, oversteer scares the passenger...understeer scares the driver.

In a StealthV calibration, traction control and stability systems are not changed from the factory settings for the obvious reasons you mentioned Aaron. TM does not equal TCS.

Under and oversteer... Many cones have given their lives to both afflictions.
So torque management is basically throttle and timing curve manipulation?... or is that question over simplified?

Close, but not quite.
