I obtained this map from the DynoJet / Power Commander website, they label it as "M22-041-007.pvm"

Just in case someone might find this map useful, and need it.

This is for a 2014+ ST, with no performance mods. Stock fuelling, OEM pipes, OEM air filter, you get the idea.

You also get much better off-idle fuelling (not completely snatch-free at low throttle, but better, IMO), and better overall torque in every gear.

Enjoy.

So, I've been running this map on a stock 2016 ST, Non-ES model, for a couple weeks.

I still like the smoothness of the Sport mode response to my wrist.

I'm not so thrilled with the fuel mileage. I'm not the type to bang the throttle around a lot. I use it "surgically" during my commute to maintain position .vs traffic, and I'm more inclined to chop the throttle and fall back to a cager-free zone, rather than open up the throttle. That's my style. Smooth and steady is what I want most the time.

So, I'm averaging 35 MPG. Not great.

I'm hoping it's because this map I've obtained from DynaJet, is too rich over most of the position % .vs RPM range.

I'm beginning adjustments to it with the goal of maintaining the smooth response to throttle input at (low % openings && low RPMs), and regaining whatever MPG I lost at cruise, by leaning the (mid to high openings && high RPMs).

That is, I'm gonna focus on retaining / slightly reducing the "upper left" map values, and reducing the rest of the map additions (they're mostly +8 values, up to 80 % throttle), to something less.

I plan to report back in a couple weeks, and post up the revised map, if it works as expected.

I thought so...

The adjusted map I've loaded in last week, has made a change for the better, for MPG.

The abruptness / snatchy-ness at low throttle settings, is very slightly returned. But, nothing like the "no PCFC" behavior. From a fellow who is coming off a cycle with a buttery smooth, linear, throttle response, I say it's still tolerable.

Not as bad as completely stock and that configurations on / off switch behavior, but... tolerable. I can live with it low speed / low throttle, while standing and navigating a rock garden.

OK, enough suspense: MPG went from 35 to 45.

The only thing I changed, was the map. I took the same routes, and I did not change my riding style.

Nice!

I may work the map some more, to further improve the "tolerable" low throttle behavior.

But, I'm now much happier with the mileage I'm obtaining from the cycle.

This new map, described here, is attached to this message. You may need to rename it to a .dvm file, as I had to change the name for the attachment rules to be satisfied.

Thank You for the report! I'm hopefully going to install mine today. I'm going with the 22-041-009 map to start with being that I have an aftermarket slip-on muffler.

Just to make sure I understand what you did: You used the 22-041-007 map and leaned it out using the mid and/or high dials that are on the PCFC unit?

I see the confusion, let me attempt to clarify.

Yes, I started with the 22-041-007 map as obtained from DynoJet.

Then, I modified the map data and reloaded that into position #3 (and then, selected map #3 on the unit front panel switch).

You can see the differences in the map data by downloading the original map file from post #1, above, and then downloading the modified map file from my today's post, and compare the two from within the PC software app.

I did not / have not touched the PCFC (low / mid / high) analog adjustment dials. They remain at default, which is "0" as set by the factory, and confirmed by me at installation time.

So, briefly, the map file differences:

The original 22-041-007, is "rich" across the entire map range, with settings of "8" in every datapoint that DynoJet was willing to fill (they tell you to stay out of certain very low % throttle / RPM range values).

This richness is unnecessary, in my opinion, for most of the datapoints, *for my use case*.

I feel the throttle, and fuelling, is well behaved in most mid-to-upper % / RPM positions. It's the low throttle % / RPM, on /off behavior, that needs correcting, again *in my opinion*.

So, most of the original 22-041-007 map positions in the mid-to-upper % / RPM positions, are now changed to "0" values: No Extra Fuel.

However, the low % / RPM positions are filled with 1-to-3 data values, on a distribution curve across that low range, so that the *extra* fuelling ramps up, then ramps back to OEM "normal". So, they're no longer "8", either, but they do add fuel in the throttle range / RPM range that I'm interested in changing *for my purpose", which is to smooth the abrupt on/off like behavior at low throttle.

So, I did all that adjustments without using the front panel dials. Instead, I did it via map programming.

I'm a 40+ year experience industry, SW developer for embedded systems. This solution was trivial.

Now I get it! Makes sense and in my opinion a better way to do it. Just moving the dials it seems hard to know exactly what and how much is being changed.

Since you're installing today, this thread is worth a read-through:

http://www.yamahasupertenere.com/index.php?topic=13799.msg314438#msg314438

My biggest mistake was not inserting the USB cable deeply enough into the PCFC for the unit to connect. I kept wondering why the app. would not register the unit!?? Oh yeah, plug it in correctly...

The install went almost exactly according to the enclosed install manual. Where it did not, I talk about in that other thread.

I read through that thread some time ago and it was helpful. Install was easy. Hardest parts were figuring out how to unplug O2 sensor plugs and I had to extend the wire that goes to the TPS sensor. The wire on the PCFC (gray wire) is not long enough. Unplugging the O2 sensor plugs was a puzzle and once I figured it out...It's a breeze to unplug them. Whole install took me about 2.5 hours and that is with me taking my time and doing a couple other things while I was there along the way. Without crash bars this is easily a 2 hour or less job taking your time.

So I got it installed and was only able to take a short ride of about 15 miles and it was rush hour. My bike is a 2015 non es with the only mod being a Delkevic slip on that has the baffle removed. Prior to adding the PCFC I was getting some decel. pop. Not too bad but it was there.

Now on my testing after installation. Bike idles more smooth. A little less decel pop but it is still there slightly. But, I just did a short 15 mile ride on the highway. I am using a map that came from Dynojet 22-041-009 which is for an Arrow slip on. They have another map for a 2brothers slip on. But really I'm sure there is a miniscule difference at best in these aftermarket exhaust as far as air flow. Only difference really is appearance and sound. I did not notice any difference in power or the way the bike rides. Maybe, just (maybe) a tad bit less engine braking. I did not notice any increase in power. For our Gen 2 bikes, there are only 3 maps on the dynojet website and I've not been able to locate any other maps. One can make their own custom map but I don't feel confident enough to do this.

The main complaints I've been reading on this blog have been engine braking, off-idle stumble/stall and jerkiness at low RPM. I came from carburated cruisers. This bike stock does not seem to have any difference is jerkiness off idle stumble/stall or engine braking than any of my previous bikes. Personally I use engine braking to help me. If I don't want engine braking.....then I just hold in my clutch accordingly (friction zone) Low speed jerkiness? ...Same thing....I use my clutch or the friction zone. Off idle stumble/stall...."RPM is your friend" I've stall either coming to a stop or taking off from a stop. Has happened 3 times with my 2015. I feel I can attribute my stall to not using enough RPMs. No different than any of my other bikes and my best friend has had 3 Buells in addition to other bikes and he occasionally stalls taking off probably more than I do and I ridden with others who have stalled from a stop and I can honestly say that this has resulted from not giving their bikes enough RPM before letting off the clutch. It can happen to ANY of us. Especially if your is not paying attention all the way or even when slowing down for a red light, and the light turns green just before stopping. RPM is your friend. Give the bike a little more throttle and learn to let off the clutch more smooth.

But all in all; not enough available MAPS from dynojet for GEN 2 S10. Only 4 maps available at this time. (Zero map, map for stock parts, map for Arrow Slip on, map for 2brother's slip on) The slip on maps don't mention with baffle in or out. If one has gutted cat or Arrow headers....they're gonna have make their own map. I plan on gutting my headers and have a UNI filter kit on the way that I found for $78.00 USD shipped. After I get my gutted header and UNI filter kit installed I will take my bike to a professional to have it dyno-tuned and a custom map built from there. I've called a couple a dyno tuners and they want to install the PC themselves as well as the Arrow headers and other mods on top of the dyno and they recommended PCV. Which I can't figure out why the PCV is better if one has a dyno tuner? So......it may take me longer to find a dyno tuner who will just connect my bike to the dyno; then build a custom map and put it on my PCFC.........

It's 03:00 as I post this..after I sleep wake up...I'll take another ride and see what I can see and feel what I can feel....

OOOOkay....Had a chance to ride a couple of hundred miles today. Much better results than my last post. It seems like the tuner needs time to marinate or the ECM learns. Bike felt better today and decel pop much less than yesterday. Engine braking and low speed jerkiness less that yesterday. Overall smoothness in the first 4 gears riding under 50 mph felt smoother for sure! My butt dyno seemed to feel more pull. Some things were hard to gauge because it's kind of windy outside. Bike may be running hotter by about up to 9 degrees. Or maybe not because it is 86F outside right now.

I modified it again.

After a couple hundred miles of varied riding, I can say the low speed abruptness, is now further reduced from the Map3_03June map.

I managed to do this without changing the mid-to-high range throttle behavior.

It's now on par with the smoothness of the original (too rich) M22-041-007 map that I started with.

It does not add a bunch of richness to the low end, rather reduces it from the original map.

It does now remove all the non-zero values above 3500 RPM, and above 2% throttle position. It's a "zero map" at any throttle position, at or above cruise position / RPM.

This works well for me, as I tend to stay in the 3000-5000 RPM cruise range.

It also is now smooth at low throttle / low RPM, *and* returns 47-50 MPG at cruise above 70 MPH.

I think I'm good with this one, now, so I do not plan any further changes to it.

I put it in position #1 to remove / replace the original delivered map, now useless to me.

Rename it to Map1_10June2017.dvm
