Speed Sensor Signal Wire Location

[talonboy]

Karson,
After reading this posting, I decided to hook mine up, and use gear advanced maps. I taped into the wire at the ECM. I had to play with the settings to get it to display the correct gear all the time, but I finally got it. I have the LCD display, and used that to calibrate the gears. Is there any noticeable benefit? I don't really know.

As far as the dual channel auto-tune, there most likely would be a little benefit in tuning the cylinders separately. I have spoke with a tuner that has built a number of Kawasaki 650 twin engines. These bikes have similar intake, exhaust, and cylinder layouts as our Tenere's. He said he found a 4% difference in the mid-range, cylinder to cylinder. Everywhere else was less.

They use a cross-plane crank?

I didn't mention crank. On the Tenere, the cylinders should run about the same temp. The intake and exhaust routing is very similar. The cylinders may have very similar airflow, and need similar amounts of fuel. I don't really know, I haven't tested my bike. On a parallel or boxer twin, these things are usually true. On a V twin (front to rear), this is usually not the case.

Talonboy, thanks.

I'm grinning ear to ear Karson.

The firing order changes the timing of intake and exhaust impulses. The headers have a crossover and the intakes share an air box.

The left cylinder is next to a radiator, the right a pile of wires.

Even on a water cooled engine the temperatures are not exactly the same throughout. I haven't looked at the cooling passage routing. Maybe one cylinder runs a bit warmer than the other due to routing.

Yamaha found enough to go through the trouble and expense of 2 fuel maps and 2 o2 sensors.

Gonna go pick up a dual channel AT-300 tomorrow or friday off a buddy who sold his bike. Might have to wait till sometime next week to install it since Saturday is college football day + beer and Sunday is riding day/catch up on Bears vs Lions on DVR + beer.

Going into the tuning session Monday morning moreso for rideability, but we'll see how things shake down once the bike gets strapped down ::008::

@Talonboy - good job! Was it the dark blue wire with just the off brown dashes? I wasn't sure since a post in the speedohealer thread said there were two of them, but I could only see one like that. Kinda tight if you don't completely remove the tank.

You did all the calibrations on the center stand I take it? I wasn't too thrilled to go any further after reading that each gear needed to be calibrated at >30MPH (or is it 20?) after the initial calibration. I don't mind the slow speed to disable ABS, but something about imagining the bike launch off the centerstand through the front of my garage persuaded me not to pursue it any further. I could have strapped it to a rafter in the garage, but patience was slim


Laying off the farkling was short lived, I guess...I can see you smirking snake!

Karson,
I tapped into the blueish wire on pin 7 at the ECM. I did the initial gear calibration on the stand in the garage, and I too was afraid to rev very high. I also have the LCD, and could see the gear was not correct all the time. 5th and 6th were my main problem. I recalibrated on the road with the LCD, and all seems fine. I can get you the numbers I got, once I return home next week.

Here is what I used.
