Searched and couldn't find anything concrete... also posted in Scan & Tune and not getting any action.

Does anyone know if a tune is able to set the car to default to "Competitive Driving" mode automatically on startup? The guy tuning my car tonight with HP Tuners was fairly sure it was possible, but was unable to find anything.

I hate having to "press & hold" every time I think I might get on it...

Thanks!

I remember SLP made something like this for the F-Body 4th Gen where it would default on traction off on start up. You may want to give them a call to see if they have anything like this for the Vette.

I think the thing that lets you do this was called LapTrax-think they are gone now. Why do you need to be in Comp mode EVERY time you get in?

Blue Angel

Because the TC ruins my fun EVERY time I shift hard.

It's the "push & hold" that's annoying. If it could be reprogrammed even to eliminate the delay (so that one push set it to Competitive Mode) that would be a huge improvement.

There's a reason GM didn't do this-bet you could guess what it is if you thought about it for a second. You want FUN, just hit the button once and turn it all off and drive like MEN used to.

lol, I turn mine off every time I get in the car, its a habit now.

Bill Curlee

I contacted the person that did LAP TRAX and he stated that he could possibly supply a few more if needed.

I will see if I can find the PM and PM back this post. If he still has the LAP TRAX module, he may PM you or reply to the post.

Thanks Bill! Much Appreciated!

Really?

If you think about it for longer than a second, you'll realise GM did it wrong... it should have been one push for Competitive Driving Mode, and Push & Hold to turn the system off completely.

MEN are usually confident enough in themselves to avoid having to PROVE themselves all the time.

I'm MAN enough to admit that when I'm having FUN I like to know that the Active Handling system is working in the background in case something should go wrong either by my own doing or by an unforeseen road condition. For the record, I've experienced BOTH. I think that's the best option, especially considering all the other MEN, WOMEN and CHILDERN who co-exist with us.

I think GM made it the way it is to "CYA"... there are allot of dummies out there who would not hesitate to sue after a mistake they caused and blame it on their car...

Blue Angel

Yes, it is a CYA thing for sure to have the system default back to ON with every ignition cycle, but a single push for OFF and a Push & Hold for C-D Mode is backwards since C-D Mode is infinitely safer than defeating the system completely.

I think someone at GM got all caught up in the novelty of having this "wild" Competitive Mode be something not entirely obvious to the driver... "Check this out. This button turns the Stability Control System on and off, but watch what happens when I hold the button down for five seconds... Competitive Driving Mode! That sounds CRAZY, like, for racetracks and stuff!"

Of course they are going to make the standard mode the "safest" to protect themselves from people thinking they have better driving skills than they actually do.

Bring this thread back from the dead!
Pushing the traction control button for 5 seconds every time I drive is annoying.
I found 2 ways for the system to default to Comp mode (Trac control off, Active handling ON). Not all C5's have this of course. Lap Trax is out of business, so....

Option #1. KPTechnologies Flexible Memory Module $50 http://www.kptechnologies.com/produc...odel=Universal

Option #2. Mini Time Delay From Amazon ($20). This is a cool little programable timer. Can program it to energize a circuit for 5 seconds (or more), a certain time after starting car or right away. You will need a $5 relay because the Trac button uses a ground circuit.
Anyone try or use either? Thoughts? I found the wiring diagram for the Trac button, that's easy. Everything can be wired (3 wires) right at the BCM passenger floorboard, or at the Trac button. There are cheaper time delays on amazon with great reviews but this one was the smallest (the size of a postage stamp). Pressing the Trac button again will cancel the Comp mode for rainy days on either option.

Those little timers are pretty awesome, can be used to turn off a light in case you leave it on, or start a cooling fan after charging system stabilizes and shut it off a while after shutting down car. Very programmable.

I want to remain in Comp mode, because every time someone wants to race me, and I loose a little bit of traction, the system bogs the car TOO MUCH.

Bill Curlee

Excellent work and information! THANK YOU for all your research!

My solution is to limit the amount of timing being pulled by traction control in the tune. Rear still wants to break traction even with traction control on dry pavement. Got to be gentle with the throttle on wet pavement of course but car doesn't see wet all that often.

Bill Dearborn

The problem with doing that is the PCM pulls timing at the request of the EBTCM. The EBTCM controls the Traction Control and Active Handling functions. If the PCM can't control torque sufficiently to suit the EBTCM it then applies the rear brakes as needed. You can make it impossible for the PCM to reduce torque but the system will still apply the brakes.

If you don't believe me just swap the stock front and rear wheels so the larger diameter wheels are on the front of the car. Then with traction control on let the car coast down hill in neutral with the engine idling. TC will bring the car to a stop without the driver touching the brakes.

Good information. One other wish would be to have competitive driving on and to be able to turn off the DIC message so that other functions could be viewed while in CD.

enoniam

Thanks, but I'll pass on going to all of that trouble since I know that the car doesn't bog like it used to when the Traction Control Active message is displayed.

On a C5?

Patches

I ordered one of these and installed one and it works as advertised. It is nice not to have to hold the TC/AH button down. I do have to hit the DIC reset button to wipe the display though.
