Mayor from what I have seen 1700 is pretty damn close to 13 afr.  Which leads me to believe the ecm varies the bias voltage it puts out for some reason.

[mayor]

that's what I was afraid of as well Joe, which makes using a formula to determine % of change pretty difficult.  I think I could rework my chart to show 1700 as a target and not 1772, and not affect the test too much since the % of change won't get too far out of whack.  

wurk, I think Bob just wants to look at whether the principal is sound.  I think his response regarding TTS was so that we simply stay on topic, and not get side tracked by what TTS may or may not do.  I agree completely that this is going to be no small task for a DIYer without software.

Mayor,
Once you know what voltage the sensor outputs (1772?) at your target AFR (13.2) 13 you will have your target tune voltage.

yea, but I'm lazy and want to have a chart ready so I can do the test while I'm already sampling the other cylinder.     I will see if the first set of pulls will give me a sufficient valification on the target.  I doubt I get lucky and see anywhere to start, but you never know.  My target is going to be 13 for this test, just so Steve doesn't bring up any magic 13.2 number comments again.

I think you may be on to something.  My posted runs seem to fall in a 1720-1760 patern after getting the AFR close enough, which would be 13.2-13.9 afr range based on the chart I made.  The sampled range was actually slightly tighter and richer than that, coming in at about 12.9-13.5.

You guys really need to ride around with a PowerVision watching the o2s live on a bike that had been fully tuned on a wideband.  It would really put this stuff into perspective.  You may start to rethink everything.

Been there, done that, Andy.  And... we with Big Twins have far better data, including the NB sensor read outs.  With TTS, the data stream, to me, seems to easier to read and understand in Datamaster.

Yes, I feel a bit snookered and I AM like the biggest Fanboi of TTS.  With my dyno, I feel that I consistently gather the best data and can get the best all around tunes with TTS.

I simply do NOT feel this will make it to DIYers... adjusting like we all adjust with the WBs to bring in the AFR line on home.  For a TRUE DIY tool to be used, a software version will need to be made and distributed.

There are even tuners who have never used the dyno O2 to sniff and bring it home... they use Twin Scan or DL to make the process automated.  If a dyno shop will not pull in VEs with =+ or - on the VE table, as compared to fuel, how can we expect DIYers to do the same.

It is MY thoughts that Bob just keeps throwing this out there.  I THOUGHT this was the opening guns to make us use our minds, and tools, to change folks minds that this COULD work for both DIY and Dyno guys.

But...  If I take Bob on completely face value, and there is NO tools that he is aware of... what is the point?  From my own understanding on DIY guys on the various forums...  I can name less than 6 that would even attempt this at all.  Generally DIY guys have not much of a clue and it is why it is fun for me and Mayor to teach TTS to the masses.

I have and use Teamviewer, if I had a DIY guy willing, it would really take me or Mike, using Teamviewer to get this accomplished.

OTOH, if Bob has crap up he sleeve, for Steve, NOW would be a good time to spill a little, or this is going to die out like the other five threads on the butthead tech talk site... BTT.

I, for one, wish to move MY knowledge forward, and also wish to help DIYers, and I, again, don't see it fellas.

I will try to get some more data runs to insure repeatability.  I will show it on graph form and through mega log viewer to give a better representation of what voltages equals what air fuel ratio.

[Buckeye_Tuning]

If we are to be able to help DIYers, online.  Is 1722 the correct MV, Bob.

Thanks Joe, I will look forward to that.

If you email me the log, I can help you set it up.

Will do Andy I just want the O2 voltage to be just one decimal more accurate BC it will only show 1.7 or 1.6.  I just need to learn how to use the program a little better.

John, and others if applicable,
Sorry for saying something you don't agree with and I am sorry there have been incorrect assumptions by you as well as others. It has wasted a lot of energy and to date, the question has not been answered other than conjecture.
Face value? Since you and others have assumed my intensions were deceptive and now you are crapped out that I wasn't deceiving you and shilling a new upcoming product for SC?

Now I do know Steve has been working away at the latest version that have new features I have tested but WOT v-tuning has not been one of them.

Have I mentioned ideas and shared experiences with Steve Cole as an fellow former racer, gearhead, and friend? You betcha!
Do I communicate my desires as a tuner to, IMO, make the product better for me...and hopefully Most other tuners.
You betcha!

Does Steve treat me as he does others? You betcha!
Is it worth it to use a superior product with excellent tech support. You betcha!

Wish I could pin you down on one topic at a time.  I think it's interesting.

Truk

I'm sure when it is all said and done.  It will have the face of Vtune, but you target 13.2 (or something, don't quote me)  Take the mt8 and the generic O2 data log and bam, new cal after you accept it.  Probably real easy for a DIY'r that just ran a couple of vtunes.  What are most DIY doing besides blending?  Buy more equipment?   It's free to update.

 PLUS!  Your missing out on the best part.  If TTS is working on this, and it does make the update.  Bob taught us if we bother Steve enough.  Maybe we can get some analog inputs.

I wish that was true. I've been asking for front and rear VE tables to be linkable for years.

Bob

[whittlebeast]

What are you thinking with linked tables?  (That is not sarcasm. I really am asking a question)

We were just talking out EFI tuning on the Harley code today.  Still tossing around the best way to do it.  Whatever we do should be cool and way different than you have ever seen in the Harley world.  This stuff is all tunable live including the autotune can talk to the EFI on the fly.

As the programmers say "it is just typing".
