Altezza link snow button


Recommended Posts

Hi there,

I'm quite new to this, my apologies in advance.

I've tried to search for answers but unable to find anything.

My question is - the Altezzalink can communicate with the "SNOW" button via CAN / BEAN.  How do I utilise this in PCLink?  My scenario would be using the SNOW button to toggle features such as anti-lag or launch control.

Yes the Snow button is received over BEAN so can be used for other functions.  The slight trick is the button only sends a momentary "on" signal when pushed (not latched).  You can make some logic using a virtual aux to make it latch, or something like short press for on long press for off.

The Snow button is received as parameter CAN DIG #1.  The Snow lamp is by default set up to show the status of CAN DIG #1 also but you can change that in the CAN transmit stream to show the status of launch or anti-lag for instance.

Set up example below would turn on virtual aux 1with a short button press and turn off with a long button press (longer than 2 seconds).  You can then use Virtual aux 1 to activate whatever function you wanted.

I have set everything up accordingly (I used Virtual AUX2), but the input will remain "ON" when I monitor virtual Aux 2 with the F12 key, no matter what I do with the Snow Button.

Snow Button is "working" as I toggle the button the dashboard will toggle the light on / off.

Could the logic be incorrect some how?

Ok there was a mistake in my original example and a mistake in your settings too.

We have to add another virtual aux into the mix as the CAN DI is not a parameter we can use to reset the timer.

Set up like below, make sure you change your Virtual aux 2 SW cond 2 to match mine below, in your map it is set as "Aux Value1", not Aux Virtual:
