lI was reading somewhere that it needs an update to work with the cam and crank sensors on the 420a motors. Check on som neon forums, also there is a big thread on this over at team-2g, in the 420a section. From what I have heard, it works good. Its has alot of potential, not as much at the MSnS but I belive its more user friendly. I was considering this for my car but Ihave gone MSnStom
