    Laptimer Sensors

    I need some help...

    Does anyone have any experience in connecting lap timer sensors? I have a Moto-D Lap Timer and I just purchased the box extender and a sensor cable for RPM and one for throttle position. However, the documentation is lacking on how to hook them up. The tech mentioned using the ECU pins or wires and tapping in there. But I'm a little anxious about screwing around with that until I know more about what I'm doing.

    Thanks,

    Steve

    I have a 2012 Speed Triple. I'm using the Moto-D Start Next Laptimer and their box expander. There aren't any links to the documentation, which is fairly limited. The box expander has one digital input and three analog inputs. The RPM seems to be a digital input cable and the throttle position cable seems to be analog. There are two wires with one going to ground on each cable. The box expander has a cable that goes to the lap timer. That's about all I have on it.

    As I recall, there are some decent Android apps that do the same thing, AND you can get a Bluetooth ODBII dongle to connect it to the bike. No wiring required. (I've got one.)

    Play around with torque pro with said dongle for data logging etc. I think sparti did a small write up a few years ago

    I think you're right. I used the free Torque app for a bit, but I don't have a mount for my phone so it was less than useful for me. But I could see the possibilities.

    Plenty of YouTube videos of that, most just cagers on the street though.

    Laptimer Sensors

    I have messed around with iPhone apps but I want to be able to synch the rpm and throttle position with the current data provided by the lap timer. This lap timer captures data at a 50 hz rate while an iPhone or android capture data at a 1 hz rate, which isn't really very good for the speeds we run. I also have a GoPoint OBDII Bluetooth device but getting everything to work together hasn't been as productive as I hoped.

    Anyway, my goal is connecting what I have.

    Thanks

    I'm beginning to narrow this down I think.

    The ECM has two connections that go to the crankshaft sensor (A1 and A9). I cannot sort out which one to use.

    The throttle position sensor has three connections (A10, B20, and B1) B20 and B1 look like commons to the fall detection switch, the barometric pressure sensor, MAP sensor, coolant temp sensor, intake air temp sensor. So I'm guessing A10 would be correct for the laptimer.

    Any ideas on the crankshaft sensor?
