How many Gear Tooth Sensors can we use?

[BigT]

Hey everyone just a couple questions about gear tooth sensors. We were given 2 in the kit, and we want to use one for each wheel (total of 4).
1.Are we allowed to use 4, if so where in the rules does it say that?
2.Where can we get the boards, i know allegro has the Sensor part, but i can't find the board anywhere.
Thanks for any help in advanced!

You can use as many sensors as you want. We haven't figured out where to get more of the kit boards either.

It doesn't say anything about the sensor in the rules either. I am also wondering about how many sensor we can put too. I believe you can order the sensor from USDIGITAL.com.

You can also go to IFI kit apart and order more sensors as well.
