I found this PDF on the slot it website.

If I am reading this right, the SCP home analog cartridges come in 2 variants to suit the different track schemes.
2 options:
- convert your track wiring to suit the scp2 
- order the scp cartridge to suit the scalextric scheme.

If you want your cars and controllers to be useable at a club  rewiring your track is the better option.
Flipping  your analog cars' guide wiring would work to fix the direction of travel, but there are drawbacks.
- all visitor cars to your track would go in the wrong direction.
- the guide self centring on some cars would be messed-up (Even if the wires are long enough to be able to swap them over )

There is a SCP cartridge,  the 201BC that has a jumper to remove. (J1)
This being a new controller, you might be lucky and have that cartridge.
Can you tell which you have?
