Ok, you still didnt tell me much about your setup and what you want to do but hopefully this example will give you some ideas...
So in this example I have set up a virtual aux to "switch on" when wheel speed is less than 10KMH. I have assigned this virtual aux to an axis in a GP Limit table, this will give us a 6000RPM limit when the Virtual aux is on and a 10000RPM limit when the VA is off. I have then set up 4D fuel and ignition tables that are activated by this same VA. Whenever wheel speed is <10KMH, the 4D fuel will add 10% fuel and the 4D ign will retard ign 20degs.
