I think to be absolutely certain, you'd need an answer from DS themselves, the seller, or someone who has that set up and is willing to test out the rally mode.

But the manual seems to suggest that the two lane sensor is fine...

CONNECTORS:

• SENSOR: Lets you connect the sensors for lane 1 and 2.

If you're not already buying from Pendles, it might be worth contacting them. They have the combo you're looking at, and if they don't know, that probably only leaves someone who has exactly that set up.
