the NB coils don't have the ability to send out a tach singal like the early NA coils. I'm assuming you hacked into the wiring to run them? otherwise I would have just used my NA coils and there wouldn't have been a problem.

I would like to leave coils from 1,8. Because now when everything runs fine, just don't want to change something until i will get MS. But where was signal on NB? It was from ECU? I know that NB console has microcompuer wich is making signals to right. But some signals must go in from ecu or somewhere whiches controls tacho.

So pin 2K grn/org is the tachout from the ECU. You'll have to wire it to yellow/blue wire coming into your instrument cluster.
or back to the yellow/blue wire on the ignitor wiring or the yellow/blue wire coming off IG- on the diagnostic connector.
