DOH! O2 wiring

[ediehl]

After I bought my 2012 Griso a year or so ago, I removed the Power Commander, with the intent of replacing the Quad D exhaust with the Termignoni. Now I'm finally getting around to the latter, and IO can't remember where those 6 tinned wires in the O2 harness are supposed to connect! I have a dim memory of thinking, when I removed the Power Copmmander, that it would be easy to reconnect the color-coded O2 wires there, but I've yet to figure out wherr that connector is! Well, I guess I'll remove the fuel tank and look there. Argh--dreaded memory loss!

Can you not get the information from the Dynojet website?

I ~think~ I was being confused by the Power Commader/Autotune hardware. I assumed that the O2 sensor I had was from the stock Termignoni exhaust, but after lookeing around some more I'm wondering if it came with the Autotune module. The first pic below is where I think I'm supposed to plug the O2 sensor in (a connector behind the starter), and the 2nd pic is what the connector on the end of the O2 sensor I have looks like. I'll do a bit more investigation, but at this p[oint I'm thinking I just need to purchase a stock O2 sensor

I have the instructions if you need them. I installed and set that stuff up also. It is in PDF, can send it to Email.

If you have the Autotune then the O2 sensor will be a wide band sensor specifically for that application. You would have replaced the stock O2 when the Autotune was installed.

Yes, the stock O2 sensor is a 4-wire unit. That plug you found behind the starter is the correct one.

Thanks much! I've abandoned the Power Commander and Autotune, and am going back to the stock setup with the Termignoni pipe (and pretzel, which the Quad D didn't use), and then I'm going to fiddle with Guzzi Diag to get a good tuning.

If you want a quicker way with great results, you might consider purchasing a map already tweaked at http://www.griso.org/.
