I have a REX,S unit for the dt400 not made for my application but I modified the the supplied plate to line up with my application ( RT3 360 )the advance curve is not great for a 2 stroke to say the least, I asked them for a map of the curve after a lot of messing about (pinging) and they told me they didn't have one and they guessed a bit (allot) about the curve , got it mapped by an independent mob and it wasn't that good Ill find it and scan it if you want to see it. It makes it run but Ive not had a great deal of success it starts allot easier without breaking my knee but that's about it.
