Hi I have swaped my Honda919 engine for a honda 1000rr 07 engine but the rev counter will not work. I connected the signal wire to the tacho connection on the ECU ( pin 17 on the gray connector yellow and Green Wire) any thoughts

you could call atb or try picking up from a coil or ring Paul at spire sports as he runs 1 and last of all Andy bates at ab performance he is a top bloke very helpful so good luck hope this helps
