Outer Limits 4x4 Board

Hey guys just grabbed the dash off dane for the pos and was wondering does anyone know the correct size resistor to put in line with the tacho input to make a V8 run a four cylinder tacho ok? I have been told its just a resistor and if i can do this it saves me $100 to have it recalibrated...

just to be Cookie's they'll probably charge ya $99 for the resister.

i'd like to find out how ya go though, keep us informed,

i want a 308 or lexus v8 for mine,

how bout ya jut run a external tacho.

run down to tandy & get a handful of different ones & go from there

not a resister but a capacitor...small trimpot

Dunno if its correct but was told that a 4 cyl and a v8 are the same pulse calibration , as far as tacho go.
