Can anyone who is using a ZX12 with a Koso (or similar) let me know what setting you have used to get the tacho to read correctly? I am using the original tacho feed wire from the ECU, but it is clearly not readign correctly.

Can anyone confirm the settings they used to achieve the correct reading (e.g. 4s, 4p, or 2s, 1p etc etc)....?

Ta.

should be 4s 4p if its straight from the ecu

That is what it is currently set to... I figured it wouldn't be the case, as the signal is coming from the ECU, not just from tapping into a coil wire. I changed to this setting last night, and it doesn't read correctly at present...

On my previous engine (a 4s 3-cylinder bike engine), the correct setting was 2s 2p, so go figure!
