Just the one. And they aren't "mappable" from what I understand.

They have a combo of preset settings and by flicking the switches in different orders you get different combinations of fuel settings etc. And from what I understand this gives a rough map at best

I don't believe from what I've read they are that great... Maybe someone who has used one will be able to enlighten me
