Finally got my engine management sorted, I had bought another kstar unit (a much later one) but couldn't get into it as I didn't know the password.
Anyway, I managed to buy the later mapping software and a password reset tool (only works with the later bigger kstar units) so the password is now reset and the original maps are loaded back into it, I still need to wire in the MAP sensor but I have a diagram for that - all I have to do is cut the link wire on the back of the kstar plug and connect to the map sensor along with a 5v supply from the back of the same plug.
The engine note changed once the MAP was reloaded into the kstar as it compensates for where the dizzy is retarded to. Its much smoother now.
Well happy - major hurdle overcome!
