there's an install manual floating around on the net, basically you've got to set it for internal or external gate, and there was one other setting I can't remember. Then you've got to get it into P1 mode which flashes up on it's LED screen, which is where the fun begins, took me about half a tank of fuel and several hours of winding it right out in 4th gear and backing off (had a boost spike at 25 psi at one point, nearly had a fkn heart attack!), then you get it into P2 and repeat - mine ended up literally deciding it was finished learning at random, around the time I'd nearly lost my sanity lol
