i use K3 on my focus RS mate,
its does everything it says on the tin, simple to use, i have never had a software crash while mapping and for me proves VERY good, (imo of course)

i am runing 8 injectors and using sequential for normal runing but batch fire on secondery injecvtors,
you calibrate sensors which is very easy to do,

i have no idea what chip is on about with it feeling like ur mapping in 1987 coz fr me the only time i feel like that is when using DTA and most of the time when the software crashes and fucks you of!!!! :@

lol,

HAlltech is a good system too, very simple to use etc,

if money isnt an issue tho mate there is only one option..... MOTEC
