Hi peter i encountered the same problem and dropped into the too hard basket...however... i know for a fact you can buy generic el-cheapo tachos that can be used on 4 6 and 8 cyl cars.... so i'm guessing you could remove the electronics from one of these and use it??? or perhaps you could understand the circuit... next time i have my car here.. i'll scan the pcb for you... so you can work it out??? (was going to use the vn v6 tacho instrument cluster)

What's the cheapest way to convert an analogue electronic tacho, set up for a 6 cylinder, so it reads correctly for a 4 cylinder. Assuming there is no access to the internal electronics, just the external signal from the coil. (logically, the tacho requires 3 pulses for every two pulses the coil generates). 2. What's the easiest way?
