hey guys, just trying to install a tahcho in my mini. 1275 engine with standard coil.

I need to know whether to calibrate it for 1 or 2 pulses?

probably just 1 - but if that doesn't work, try 2

just a guess, but 2 would be for a wasted spark type ignition, which you don't have

You only get one chance with autometer, as it uses wire loops that need to be cut instead of switches. Or at least the last one I played with did.

Im pretty sure it will be 1 pulse on standard mini systems.

you can join the wire's back together, i think it is 1 pulse.
