hey guys need some help, i have an rb20 and my coils took a crap so i did a wasted spark setup and it runs 100x better. i have an autometer phantom series tach and tach adapter. the tach adapter got a signal from the #1 coil pack power originally and it was fine other then it would cut out in high rpm(thinking the ignitor is going). but now with it hooked up to the power feed to cylinders 1&6 for the wasted spark, the tach just bounces around. so what should i do to make my tach opperate again?

i tried using the ecu pin plus the 10K ohm resistor trick and still nothing. any ideas?
