Default Auto Tune and AFR ratios

Ok I keep seeing different threads about the auto tune setup.

I see people running all different ratios at different spots.

Admittedly it's understandable, different bikes, different configurations etc.

So I'm curious.

2012 CCT.

VM Cams, PC-V w/A-tune, Lloyd filter, unlocked ECU, timing wheel set to +2, nascar6 re baffled pipes.

I hear all these reports about bikes pulling like a freight train etc.

Well when I first got my cams and it tuned with the VFC, didn't feel like much.

Upgraded to the PC-V with A-tune, it's better but I don't feel like the bike is running all that strong. My A/F ratios have ran anywhere from 13.9(cruise) to 13.4 full throttle range to 13.7 cruise to 13.0 full throttle.

Just not noticing much difference. So i'm curious for those with similar setups to mine,

What ratio/RPM range are you running? Are you happy with your performance/mpg...?

Aren't you supposed to have it dyno tuned first then the auto tune maintains it.

2015 Suzuki V-Strom DL650 (bought new 4/26/17)
2006 Triumph Rocket III Classic
1/4 turn throttle ring
Tank riser
VM-1 DR cams
Timing wheel +4
Lloydz high-flow air cleaner
Bassani baffled OEM mufflers
PC-V 118hp 116tq
If it's not broke, make it better

that seems overly redundant.

The purpose of the auto tune is for someone who doesn't have access to a tuner, or in my case a trustworthy one.

Go get it dyno tuned by a reputable tuner , you won't believe the difference . Then you won't need the AT .

well therein lies the problem. No reputable tuner in my general area.

I'd rather not toss $200-300 towards someone unless I know they're doing their job properly.

That's why I went auto tune and I'm asking what people are running for AFR's

If I had the time I'd run to the Vic shop, it's only 6 hours away but it's late season, it would be an overnight trip and I just don't have the free time right now.

I was lucky to be in Des Moines on business a few years back, Rylan put my cams in and dialed in the VFC3 but that was his pre dyno days.

Was never really happy with the cold surging so I went to PC-V. It runs better with it but just curious what has traditionally performed the best AF range/rpm etc for my configuration?

Maybe sent Rylan a email and tell him your setting and how he could improve on them.

Well I've attached my PVM file as an attachment zipped up in case anyone is curious enough to take a look at it.

Until I can get back to Iowa and have it tuned by someone.

It could very well be that my bike is fine, just that my idea of performance greatly differs from someone elses idea of performance.

The fun thing is the ability to 'play' with the settings to find the happy spot, the downside is the butt dyno is different from person to person.

I know what the AUTO TUNE, and how it works. What I'm asking is what are people WITH my setup running for A/F ratios?

I've had it on the bike for 15,000 miles or so now(currently at almost 38,000). I've had cams in my bike since the Vic shop installed them in 2012.

I've played with various settings, fuel maps etc. Trying to find the sweet spot performance wise.

Asking if anyone wants to share their settings so that I can try them a while.

The beauty of this device is the end users ability to play with it, change it, look for better options.

I know i'm not the only Cross bike with cams/filter/etc running this tuner.
