I was just messing around with my bike and thought I would share a couple of waveforms.

Are those stock O2's with a stock tune ?
What exh. system are you running ?

They are the stock 02s, but I am running a Vance & Hines big radius exhaust with the Vance & Hines "Fuel Pak"  fuel management system.

Where did you have the amp clamp applied?

Are they true duals ?  No crossover pipe ?

They are true duals, no crossover.

And Spence, as far as the amp probe goes I will get back to you on that. I did this last summer and my diagrams are buried at the moment. I'm in the process of moving.   

As long as it has TRUE DUAL exh. you can tune each cylinder separately as long as your software is good enough to allow it. 
I ran my rear cylinder richer than the front to compensate for the added heat from the front blowing over and blocking it. Mine was a 2007 Street Glide.
I used the Daytona Twin Tech ECU and software.  It would spank the 110's without a problem  :D

Your rear O2 looks a little lean from that WF. I also used wideband O2's with the TwinTech system and it had autolearn too.

Thanks for the tip. Now you've got me wanting sink more money in my bike  [smiley=devious.gif] the wife will not be happy about this. I'm going to have to check out that management system. The system I'm running doesn't let you play around. Did you put a bigger throttle body on and if so what brand did you go with?

Nope! Stock TB.  I did get some cams and dropped those in.
The bike was all stock except for the air filter housing, the pipes, cams and push rods and the Daytona Twin Tech setup with wideband O2's. 
I dropped almost 300 degree's of heat off the rear cylinder  compared to my 2008 Ultra Classic, in stock trim.

My 07 used the TCFI with the add-on wideband controller. It's a complete ECU replacement setup and worked well with the Delphi system  [smiley=dance.gif]
Delphi was the best thing Harley ever did  [smiley=chicken1.gif] It's only money and you can't take it with you, so enjoy it while you can  [smiley=evilgrin.gif]



What model and what model year is your bike ?

That's a nice temp change. My bike is an 08' superglide custom.

The 08's run hot with the factory tune. They had to lean em out to meet EPA standards.
The TCFI with the wideband O2 setup will be a huge advantage over the VH crap  [smiley=2cents.gif]

Nice bike! 

Here's a few shots of my latest toys  :D

Sounds like it.

sweet bikes!!

some secondary ignition from my bike no problems just practice

Morning, have never looked @ wide band much but seen the 02 wave and on standards anything over 800mv rich, wondered about the blue jug but then noted the comment about running richer which is historic I guess on Harleys,I have been told.

What is the general consensus on wide band?, as the first jug looked stellar according to what I know, 200mv bottom, 800 top, and the rear jug would have been puking black from a traditional 02.

Nice Beemers by the way.  Pictures look like California,  I do ride dual sport.

If buying a beemer today probably would be the 800.

Not being contradictory just trying to learn something.

Yep! You need true duals with a capable tuner/ECU to setup the cylinders to run properly. Adding extra fuel to the rear helps to compensate for the lack of cool air to the jug. Hot air blows back and makes it run lean in comparison. Compensation makes it run properly.
