Need to tap into o2 sensor

[Revalden]

I have an AFR gauge for Spydie dash so, hopefully, that I can monitor what's happening with PCV map changes. Does anyone where/what color wire goes into the ECU?

Didn't the AFR gauge come with a broadband sensor you screw into the O2 sensor bung?

Any AFR gauge system I've ever come across - and granted, I haven't seen them all - the wide band sensor goes into a separate bung that you need to install. It's sometimes a different size. You still need to keep the original O2 sensor and circuitry intact because the standard sensor is a lambda sensor and can't drive an AFR gauge. Plus the installed standard sensor is still required to control the AFR in the closed loop portion of the fuel operating map. Without it, it'll be throwing codes. So, Rev, if you're not familiar with the fundamental operation of closed loop and open loop ops of an electronic file injection system, and how the O2 sensor controls the AFR, you'll just get yourself all balled up playing with maps. You'll be trying to adjust AFR and the system will be adjusting it back to where it was. Then you'll start fighting codes. It's just another reason why I think an ECU flash is the better way to go than the Power Commander now that a flash is available.

But, the Autotune system from Dynojet is made to work with the PCV. Perhaps that would be a better fit for you.

On the other hand, if you have a different kind of gauge system that works with the standard sensor, then by all means, train us up.

The last bike I did an AFR on was a Victory 106" that I had already removed the O2 sensors from due to a Dobeck tuner I was using. So the O2 bungs were unused and plugged.

Understand. Different tuner, then. His PCV retains the existing sensor.

Ok, Thanks for the heads-up about the o2 sensor. I'll leave that alone. I might get the AutoTune next month b'cuz I've already spent my monthly "allowance".:gaah: I've got to get this PCV up and running for our S.C.R.C. Wild Hog Week End run to Arkansas.
