i have done it.
it turns out you HAVE to wire up the hks fcd with ignition OF and the hks fcd HAS to be on setting 12 when wiring it up and starting car for first time.
then an settings HAVE to be done with ignition ON.
now running full 16 psi on ct9 without issue and set it up tonight with my wideband (what a piece of kit)
12.3 air / fuel on full boost, and pulls so hard it scares me,the boost comes in so savagely andi am very surprised me clutch isnt slipping either
thanks again for all your help and i hope the administration can add to the fcd fitting guide about the setting it has to be on before fitting and any adjustments made.
cheers
