You have the Wideband on your Vmax? I just picked one up for my YZF, and I will be sending my mid collector to Graves (it's titanium) to have a ti bung welded in.
How much trouble was the overall kit to install?
It was one I originally installed on my Wifes 350Z that I put an ATI supercharger on. Had it laying around in the garage and hated to see it go to waste.
Installing it was a piece of cake. The brain is under the rear seat where the tool kit used to be.
The guage is mounted in a guage cup bolted to the right of my speedometer in a hole I drilled and tapped into the handle bar support thingie.
The data logging switch is mounted on the neck cowling.
I'm using the RPM function to drive a shift light.
The only functions I'm using are the A/F and the RPM input.
On your YZF you should have a throttle position sensor you can tap into for that input if you wanted. I don't use mine although I did figure out that the Max does have a 5 volt power source that would drive a throttle sensor if one could be found to fit. It's the TCI power supply going to the MAP sensor on our bikes.
It's pretty cool being able to datalog this stuff and play it back on a laptop but with the way I'm using mine I rarely even do that since the novelty wore off. The guage was my main goal anyway and it's a nice way to keep an eye on the Vmax's finnicky carbs.
The Wideband does a whole lot of stuff that they really don't advertise except for in the installation manual. You can program it for certain outputs based on various input conditions which would make it really handy for nitrous. On my wifes car I had it set up to drive a retard signal back to the ignition if throttle postion, rpm, and A/F met the parameters of what I considered dangerous lean burn/detonation territory.
Later,
