ok ive been looking over my go-tech ecu and i was finding it realy hard to set a stedy idal i then descovered that cilinders 2 and 3 were not sparking so i changed the coil pack leads and for the sake of it the plugs problem still there i remover the plug from the coil pack pin number 2 is an ignition live as i expected and pin number 1 and 3 switch as they should yet still no spark the only thing i can bring it down to is the charging time of the coil pack maby?? when reved slightly the spark comes back but on idal it goes away

any idears what i should set the charge time on the coil to?
