DET rev counter prob fix (theory)

[umpkin]

can the rev counter on the s12 pick up the signal from one coil pack??? having looked inside my rev counter last night, i see a potentiometer same as what used to be on fords, this was used to change the sensitivity, depending on if it was used on 4 cyl or 6 cyl, so im guessing that you might be able to tune it to 2 cyl, or poss even 1 cyl pending on the spark freq on the det coil.
