Whats the difference between normal, "Traction Control Off", and "Snow" modes?

by **Dodgy Guy** » Wed Mar 14, 2007 8:31 am

TRC off turns traction control off

Snow control heavily moderates the traction control (ie acceleration is not as good)

Is it auto? I think it shifts at a lower point in snow mode. Old mans Cefiro does anyway.

It's manual. So what function does the traction contro do then?

by **Alex B** » Wed Mar 14, 2007 5:35 pm

What it says in the name, stops the car from loosing traction, probably using abs or retarding the engine somehow.

in Altezza it affects the throttle directly. When you press the gas pedal you don't actually open throttle directly, what happens you changing position of a potentiomenter (almost identical to TPS) which sends signal to ECU, which sends signal to throttle servo which opens the throttle, in this way the ECU got full control what throttle does (well almost) and it can control completely the power output of the engine. This system does not have an idle control valve either, it gets away by constantly keeping the throttle open...

apparently snow 'locks' the diff ....seems to make mine a lot more slippery in the wet lol deff doesnt reduce power

Sergei are you saying that acceleration can be improved by turning TRC off then?

Also on a tangent did the RS200 Z come with an LSD?

I know if i do a dencent launch i pull a better 1/4 in my rs200 with the trc off. I find it kicks in a tad to early.

As far as LSD's go see http://forum.altezzaclub.org.au/index.php?showtopic=946

no it doesnt.

it works on the engine only

what does it do to the engine Rev?

by **Mr Revhead** » Thu Mar 15, 2007 10:57 am

as above..... traction control. just harsher.

by **kinggts25** » Thu Mar 29, 2007 10:53 am

why are you able to turn trc off and snow on then? its weird lol anyone got the factory manual?

by **Jebus** » Thu Mar 29, 2007 10:55 am

TRC is Normal Traction Control
Snow is Traction Control but harsher

You have one or the other. You cant turn both on and have SUPER TRACTION CONTROL!!!111!

got a translated one here

as well as the wiring diagrams

by **Dodgy Guy** » Thu Mar 29, 2007 6:38 pm

3 options:

TRC on

SNOW on

TRC and SNOW off

the last one is the best :twisted:

How much?

I believe that the Snow button affects the cam timing and the throttle control, to give smoother acceleration in the snow to try and prevent the traction control from having to activate.

i.e. you stamp on the gas pedal hard in snow mode and instead of taking 1/100's second for the throtle plate to open, it takes 75/100's second to go slowly from closed to open, and things like that.

And cruise at 100k in our one which was an auto and press the snow mode,
you can hear the engine change note, but no speed is gained or lost, as the cam timing alters.
