High ohm injectors, does pwm always has to bee 100% and 25,5 ms?
i have some tach spikes random. rpm drops about 1000 rpm.
is there any idea to change pwm? or should it always be at 100 and 25,4?
woundering..

I run highZ injectors with those settings and have no tach problems, I`d be looking into the wiring. They aren`t designed to run peak and hold so if you altered the PWM you`ll probably just see bad side effects and no benifits.

Which car is it? if either run Edis you could try resistor spark plugs to cut down any interference to the MS unit.
