cant seem to find much info on this and its really annoying not having a tach.

i dont remember what version it is ill have to check again and i do have a tach output set up but im having a problem finding what resistor to use to get it working correctly. right now i can connect an aftermarket tach and it will work.

its a stock 1.8t crank trigger i think that sounds right

hey any idea if this will also work for gm dual tower coils? do you bypass the high ohm resistor and use the tach out on the ms?

So i have a 91 vw gti with a 20v swap and megasquirt running gm dual tower coils and i cant seem to find any info on geting the tach to function...
