I am planning on getting 2 tunes for my upcoming XCal2. One for the street, one for the track. Can the track tune be set up to default the traction control to off? I don't want to have to remember to turn it off every time I start the car at the track.

howarmat

yes, just ask the tuner to do so.

I remember seeing a thread that said the tuner could deactivate the TCS but it would be off permanently (it cannot be turned back on with the TCS button) until you load your regular tune (which has it on as the start up default).

howarmat

Which is exactly what he is doing......

spike

True, but he only asked if it could default to off, not if it would be permanently deactivated. Just wanted to make sure he knew that he might not be able to turn it back on without loading the street tune.

Thanks guys, I appreciate the input.

If the TCS is disabled in the tune, you will get a warning on the message center EVERY time you turn the ignition on that the system is not functioning. Then you must push the Reset button to clear the message. So, whether the system is disabled or not, you must push a button:

1) Disabled -- Push Reset, or
2) Enabled -- Push the TCS button to turn it off.

For me, it's not worth disabling it because you will have the push the Reset button every time you start the engine. With it enabled (stock), the only time you'll need to push the TCS button to turn it off would be at the track.

If I forget to turn off the TCS before a road race, my brakes are toast. I'd rather not have that problem.

You will notice immediately. Just get into the routine of hitting the button. It's not rocket science.

Yes, you will notice if it is enabled the first time you hit the gas and the car shuts down on you for a second. You will remember then!!

I forgot the other night when I went drag racing to turn it off before i tried to do a small burnout. It didn't work out so well. I remembered then, and turned it off. I had already embarrassed myself though. Oh well!!

If having the TCS disable thru the tune causes a message to pop up in the message center, can I just ignore it, or do I have to reset it every time I start the car, as was stated above?

max2000jp

You have to reset it everytime you start the car. An error message pops up on your onboard computer.

Jon,

You don't physically HAVE to push the reset button but this warning is similar to the low fuel level warning. If you don't hit Reset, it won't go away. It's kind of a pain and why I elected not to disable TCS.

My TCS was disabled by a tune I got from Tillman Speed, and I never had to hit reset. The computer never complained at all. The only annoyance was the light for the TCS inside the tachometer stayed light.

My TCS was disabled....and I never had to hit reset. The computer never complained at all.

When you say "computer", do you mean the message center display? This is where I read the message. You do not have to hit the Reset unless you want the display to go back to mileage, etc....

Agreed.

I write my own tunes and noticed something interesting about the TCS scalar. One would think it is a binary switch, i.e. "0" = Off / "1" = On but it is not. The scalar range is from 0 to 99 where "0" = Permanently Disable. I have not experimented with this scalar value but wonder now what the difference would be, for example, between a "40" and a "90"....... Could this somehow be varying degrees of "disability"? In other words, I wonder what value your scalar is. Mine is set to "46" and it is enabled. Maybe different values cause the PCM to react slightly differently and this is why your result is different from mine? Food for thought...

Yes I was refering to the message center, where it tells you when the gas is low, etc. I never had a peep from it about the TCS being disabled, so perhaps your are correct about the scaler range.
