Target tune closer to coming to market?

[FLTRI]

Forgot to add, location of wide bands. Stock 12mm bung holes were drilled out to accept 18mm bungs. You are a bit limited to bung locations with stock head pipes.
Jeff

Do you have a specific reason for not putting the 18mm bungs up about 6" from the exhaust port as normally spec'd?

They may not be 6 inches from the port but are not far off. The rear pipe install is compromised by the lack of space, it's tight to the cylinder and engine casting.
So, it was easier and more convenient to install where I put them plus I was expecting the wide bands to be more forgiving to the location than the narrow bands.
At the end of the day, I've tried the location and if it doesn't work out I will move them, probably having to modify the heat shields as I go.  Next step for the moment tho is to put the end caps on the exhaust and see if that helps reduce the reversion.

I was going to ask about that.  I came to the conclusion drill and tap was a possible.  How tight was it near the clutch on the rear with larger WB sensors? Funny how the front location looks better then the rear, yet the front is the problem child, even Chris's with the Akro pipe with totally different locations. Leads one to believe it's reversion more then anything else. Stock cans look really restrictive in comparision, reducing the problem.

Hi Ron,
The sensor fitted nicely right in the middle between pipe and cylinder. Looked real tidy.
Hopefully with some back pressure from the end caps reversion will be a bit more controllable.
How can I tell which cylinder is causing the problem, or could it be both ?

You will likely see unstable integrators and large aff drifting in the problem cyl. The good one will change very little. I'd suspect the front one.

My TT is working well on the 103. The Autotune is faster than the previous A/T pro.
My CLI's and AFFs are nearly , and mostly , 100% time after time in cruise.
So far so good.

[Sunny Jim]

And then the issues appeared!
2 different TT cals have worked successfully until I tried to introduce a variation to the tune .
I auto tuned both cals on separate occasions successfully.
The problem cane when I attempted to alter the target AFRs,then accel enrichment and timing.
I took the Autotune result and looked at the tune in winpv.
Made my alteration and flashed the tune back into the bike ( on both cals @ separate times).
When I rode the bike the AFRs went haywire. Tried A/tuning the set cal but to no avail.
Maybe I am doing it wrong but I thing I have it right.
Seeking answers and please.

Oh great. I modified Mossy73's vrod cal to what I felt were better afr for the v rod in the idle and low end. Warmup table as well. I've not heard back from him so either it's ok or he wants to kick me in the nuts.
Should be a simple edit and it just retunes to the new value. Maybe not.

[Jamie Long]

If you had 2 calibrations that were working properly and then you made some adjustments and now TT is not working, something was likely adjusted or set incorrectly. Please email me the original cals as well as the altered ones to jamie@fuelmotousa.com and I will take a look. As a test simply re-load your earlier tune and verify it works correctly, as a side note make sure you did not open your TT maps in an earlier version of WinPv as this will bust the tune.

Target Tune calibration adjustments are no different than anything else, just make absolutely sure the TT cal is opened in WinPv software 2.0.18-1500 software. Opening a TT map in an earlier version of sw strips out the Target Tune tables

Good to know. I'm sure he's updated and if I recall I only sent him a jpg sample to go by.

Jamie, I will check it tomorrow and send info. I did reset the original TT cals and they both worked fine. I felt  certain my software was correct especially that I can select the wideband TT Autotune option.
As I said I may be doing something wrong.
I will follow it up tomorrow now I am on break.
Might I add, the cals worked exceptionally well after a couple. Of ATs.
It was when I made the slightest alteration that they both independently went haywire.

[joe_lyons]

That option is from the Power Vision itself which uses firmware, Jamie is talking about the software version on the computer

[Sunny Jim]

Joe,Presumably that is in update client software.

5.00pm here.
Started from the beginning.
Downloaded correct software again as Jamie suggested.
Checked everything throughly.
Loaded the FM cal provided.
Ran bike - installed variations to the cal/ flashed cal and road bike.
Bingo!🏁
Everything is sweet.
Software!
No more issues!
Bike has never run better.
We will try it on the 120r in a few weeks.
Thanks again HTT.- Gold!👌

Could you get a big log and post it up.  I would love to see how the tuning is coming along.

Glad to here it is running great for you.

Andy, happy to do so, but it will probably not eventuate until next week end. Stay tuned! (No pun intended)

I did some testing today with the new Target Tune...

Here is a plot coming off the Target Tune after I made just a few tweaks of what Jamie at Fuelmoto sent me as a first try.

Compared to what I got several years ago after a year of tuning.

This thing flat works.

[q1svt]

whittlebeast, can you share of few details of your build?

[whittlebeast]

2007 Sporty with Harley Heavy Breather to keep IATs in check.  Now the IATs average about 20 degrees over ambient.  That is it on the engine side of things.

I do have BIG Brembo brakes, custom rear shocks, air assist front forks and a custom wind screen.  It rides just as you would expect it to ride.  Stock, I could not stand it.  The stock fueling was horrible, it constantly bounced off the shock limiters, and simply did not stop.
