msd setup is more reliable than microtouch imo.there were microtouch stories a few years back but maybe quality has improved??
set the cylinder count to 3 for lower kick in rpm.
do not mount the solenoid directly on pipe or motor,vibration will kill it.
not sure but i think msd enhancer (kawi version has it) cdi (if you use one) has a tach output for ecwi so no looping stupid wire around plug lead.
water filter is needed and ensure all connections are soldered and sealed.
best position for injector is on headpipe near exhaust manifold mounting flange .
