in a race are you launching with or without TCS? i've found that the car bogs on me with the TCS on and the car is much more fun to drive (love it when the back in slides out) with the TCS off.

last night i was practicing launching the car (can't do much it's new and don't wanna go over 4 grand) and it would bog if the tcs was on. anyone got any tips or suggestions?

 

MT or AT?

 

MT, i wouldn't be caught dead in an automatic (no offense to anyone)

 

I always turn it off if I am racing, we are talking about the VDC option correct?/

 

you will get a faster launch with it off, no doubt.

 

What model do you have? The shut-off switch for my track model is for VDC and unfortunately, it does not switch it off completely. I believe that TCS is on whether or not the switch is used.

Sports Compact Car ran a story on mods to the 350Z awhile ago and found TCS to be a impossible to turn-off without disconnecting the brake switch.

 

isn't VDC only available on the touring package? TCS is traction control and is on every model i believe. so far i've done a few launches with it off and it's a lot better off the line. but i still dont know if VDC and TCS are the same, i believe they are different.

 

i believe you are wrong, i have the article and they said that when they tired to heel toe they couldn't do it because when you tap the brakes the throttle is cut back i believe. hmmm...have to check when i get off work.

 

BTW i have an enthusiast model.

 

The switch definitely turns off TCS/VDC since you can spin, do donuts, and peel out easily when the switch is off.

When you step on the brake, the throttle response is lowered, and that can not be turned off without modifications. I can't really heel-toe, so I don't know if it helps or hinders. It may make it easier to heel-toe because the lower response makes it easier to rev match, but I don't have enough experience to know for sure.

The Touring 6MT, Performance, and Track have TCS/VDC, while the Enthusiast and Touring 5AT have only TCS. I don't think the Base has anything, but it may have only TCS also.

-D'oh!

well i read the article again last night and SCC said when they pressed the brake and the gas at the same time that throttle was cut automaticly. the only way to get rid of that is to disconnect the rear brake light (isn't that kinda weird?)

 

There is another thread floating around this site somewhere in which Skidazzle posted the wiring schematic (from the service manual) and discussed possible ways of disconnecting that "feature".

Yeah, it makes sense that you wouldn't want to change the throttle response for a rev match, because one fequently matches revs without the brake so I can see that you wouldn't want the feel to change when you start braking too.

I'll have to try this in my car sometime.

-D'oh!

 

heh, i'm feeling a lot more confident in the car but still kinda shaky (which is a good thing, it helps me know my limits and not to push them) and i've been messing around with some of my techniques. i have to use throttle now vs braking to get the back end out which i'm not use to. i'm use to hell/toeing getting the back end to come around from there to exit a sharp corner faster. needless to say i get lots of looks doing this. apparantly i can't do it in the Z because if you hit both the throttle is cut back. kinda sucks though because i can't do some more advanced manuevers. hmmm...need to figure something out. i'm gonna talk to a tech tomorrow and see if i can get a wiring diagram and how many to disable it.

 

OK, I tried this out yesterday, as I was rolling down a hill. I used my left foot to softly apply the brake, and my right to blip the throttle. I then repeated the test without using the brake.

To me, the throttle response seemed to be the same, and since this test (as well as heel-toe shifting) are under a no-load condition, maybe there isn't a noticeble affect on throttle response.

Anyhow, I'd be interested to hear what any of your personal experiences are, in real world driving/racing situations (not some SCC burn-out test). From my (limited) experience, I don't think it is necessary to remove the circuitry.

-D'oh!

 

Does turning off the Traction Control (I don't have VCS) activate POSI like with the LS1's where both wheels spin instead of one?

 

Hmm,

The rear diff is a viscous limited slip (for those who have the LSD), so TCS should not have anything to do with it. It is completely passive as far as I know.

-D'oh!
