Hotfoot Posted January 24, 2014 Report Share Posted January 24, 2014 OK I need a little help. I've got a Starlane laptimer newly installed on the BMW S1000rr and want to connect the RPM sensor. It says you can do that by wrapping a sensor wire around the ignition coil to pick up an RPM signal but we can't get that to work. I called Yoyodyne and they said it is very difficult on the BMW to get a signal and the best thing is to just tap into the signal wire the feeds the RPM info to the tach. Anybody know what wire that is or how to find it? As far as I know the BMW has a complex canbus and I'm not sure there IS a simple tach signal wire. Yoyodyne suggested we call our dyno expert and ask them what wire they hook into for RPM when running the bike on the dyno. So... Timmer? Any thoughts? I have an older version Starlane on my Moriwaki and it picks up an RPM signal off the Moriwaki iginition wire with no trouble at all. But the new timer won't pick up a signal off the YZ450 Super Single rpm wire either, I have the same problem with THAT bike, so I'm trying to find a solution for that one, too.
