Wow, nice gains. This actually might be worth throwing away my lifetime warranty for.
lifetime warranty?

Yeah my local dealer offers lifetime warranty on brand new bikes as long as its the same owner and work is carried out by them. I doubt they'd stick to that after a reflash though

They can't tell. The ECU flash protocol is designed to work 100% seamlessly with OEM diagnostics. We design it this way and test for this :)

So if you ever should have to be hooked up to KDS - it will respond and give back diagnostics info all the same. The only way to tell definitively is to dump the ROM contents which dealerships do not have the capability to do nor do they have the techs to comprehend the readouts. If you're worried about warranty, it is a minute or two to return to stock before bringing the bike in for repair or service. Then when you get it back home, another minute or two to reload your last saved map file from the ECU from before you brought it in. All of my bikes are tuned through the ECU - all of them are also still in their original warranty or extended warranty ;)

Question about ecu flashing. The manuals says that the cruise control has a maxium of 85 mph. Is this an ecu variable that can be modified? 85 is probably fine for a CC limit I was just wondering, theoretically, if it can be changed with your flash setup? :D

I'm no expert but without a dynamometer I dont think you can do any tuning yourself... You might be able to de-restrict it, but tha's about it.. see with your local tuner..

We are just getting into the ECU so there is still a lot to find and a lot of things to add based on feedback from owners. This is one thing I can suggest to be looked at. So long story short, as it sits right now? Not, that is not adjustable as of yet. But, thats not to say it can't or won't be adjustable. We are always looking on adding new things to the bikes we support.

I would hold off until we get a read out of the US ECU (I will keep people notified). In the mean time, I will kind of explain the differences between the two kits; the USB M v3 and the Log Box M v3

The USB M v3 is a basic, manual tuning system that allows you to make changes to all the tuning parameters on the bike as well as change things like fan temps, rev limiters as well as enable new features like disabling closed loop fuel control or off throttle fuel cut. In addition to all of that, it also lets us access live engine data which is useful in on the dyno tuning or in the garage troubleshooting. Finally, this interface allows us access to view and clear service codes in the software with one click. No more having to do multiple button presses and holds and then consult the manual - it tells you want it is and gives you a single button to click to clear them.

Now, the Log Box, this does everything the USB M v3 does and more. What it adds is a different style tuning interface one that accepts a wideband O2 sensor (Zeitronix ZT3 /w Bosch LSU 4.9 sensor) and one with 16GB of on board storage so you can do full on data logging. In addition with both of these features we can do auto tuning of the both the off/low-mid throttle IAP fuel maps and the higher input throttle based fuel maps. This is a lot more advanced than say a piggyback auto tuning system - where there sample rate is in the range of 8-10 samples a second, on the H2 SX (and SE) it will be 100x a second. So it works and it works well. More importantly it has the sample speed to keep up with a bike like the H2 SX so no data is lost during hard acceleration. Furthermore the auto tune can be used on the street, track or dyno and also has the ability to use our new AutoTune Live feature and Data Viewer Live feature. This is essentially the the be all end all solution.

Now there are a few things tossed out there, live engine data, data logging, auto tuning, auto tune live, data viewer, live, etc.

Live engine data is just as it says, it displays pertinent engine data parameters live while connected to the bike:
Screenshot 2018-03-16 21.22.06.png
As mentioned this is largely beneficial tuning the bike or say troubleshooting an issue like maybe the bikes TPS isn't reading 100%

Next is data logging and it is just as it sounds. It's highly configurable so you can run as many tables as you want with as many parameters customizing them all down to the line style, line weight and line color. Here is a sample from my 16 ZX-10R:
Screenshot 2018-03-16 21.24.27.png
You'll see I have four charts with some charts with multiple logged parameters:
1) is TPS (throttle position) and ETV (electronic throttle) this allows me to see how far bad behind the electronic throttle is lagging in comparison to the physical throttle. Looking at it this way lets me adjust the sensitivity and harshness of the the throttle as well as maybe dial it back a bit if while in a race in a particular gear in a particular section the bikes throttle is too sensitive wanting the front end to lift - I can dial it back a bit. Or if the throttle is too laggy, I can see that in the graph, reference it in the ETV tables and adjust it to make the ETV values follow more closely to the TPS values giving it a more 1:1 throttle feeling typically seen on a traditional cable throttle setup.
2) Gear and RPM (self explanatory)
3) IAP and AFR - AFR we all know is air fuel ratio. IAP is the difference between manifold pressure and atmospheric pressure. This is the fuel map the bike goes to when in low throttle and off throttle.
4) Front wheel speed/rear wheel speed - self explanatory.
Again you can customize this any way you want... Obviously there are some values we include in there that would serve no purpose because the bike isn't fitted with such a sensor, a la boost pressure on a Ninja 300 :)

Auto Tuning - just as it says. A way to automatically tune both the IAP and TPS fuel maps of the back based on observed and recorded actual data from the bike:
Screenshot 2018-03-16 21.31.17.png
So here you have a few things going on... You can isolate the changes per gear (per power/drive mode as well if wanted) and the ability to drop between the TPS and IAP fuel maps.
The meat and potatoes will be in the tabs below: logged AFR, Data Count, Target AFR, % Map Change and Auto Tuned Map
Logged AFR - self explanatory. Also if you select the fuel cell you can then see the individual data on the right hand side from each sample with the data variables recorded in that sample.
Data count - shows exactly how many hits of data per each individual cell
Target AFR - this is your desired AFR table. We have a default table we include for each bike through testing that tries to achieve the a safe high output in performance as well as a leaner cruising range to maximize fuel economy. You don't have to use it though! You can totally change the values to whatever you want.
% Map Change shows you the approximate change of fuel you need to add or pull to get it from the logged AFR value to the desired AFR value
Auto Tuned Map - Shows you the before and after fuel map changes and is actually where you apply the fuel map changes
Furthermore, this is highly configurable in the filters and settings screen - things from ensuring good data based on the measurements of your exhaust, to adjusting the transition tables to gather more data to help make the throttle even more smooth, etc, etc. This is a whole subject in itself.

Next things would be Auto Tune Live and Data Viewer Live. These are both relatively new functions that further expanded on utilities that were in the software, but kind of hidden to those who didn't have an in depth knowledge of the software and it's abilities. So... a few teasers :)

Data Viewer Live:


AutoTune Live:



Pretty cool eh?


Now for those that want a more in depth explanation of it all...
Data Viewer Live How To:


AutoTune Live How To:



Additionally we will be rolling out "Race Tools" to this model. I don't think the base model has the nice things like KQS up/down or KLCM yeah? Just the SX SE right? Please, correct me if I am wrong. Anyways if that is the case, then you will have the option to do this in the base model (and make the SX SE versions adjustable)
Pit Limiter:
Not sure how many people would get a use out of this on the H2 SX but it basically is used on the track where you are supposed to stay under a certain speed limit to avoid penalties as well as promote safety. Here is a video of it in action on a team we support in Aussie SBK on their 2017 GSXR 1000R:


Next up would be engine warm up, again primarily a race feature used at the track to get the fluids moving and promote engine warm up by applying blips to the throttle automatically and once it reaches the cut off temp, idle returns to normal(fully adjustable):


Quickshifter/Autoblipper - clutchless upshifts/downshifts. Here is a video from our R1 race tools:


And here is a sample screen of what Race Tools looks like (dang looks like you can only upload three photos):
Link here: https://www.dropbox.com/s/0y64gpc6be665 ... 0.png?dl=0

Fully adjustable suite, from the QS kill times per RPM, per throttle position and per gear to the auto blipper settings per RPM and gear as well as the amount of blip desired... sensor sensitivity, minimum activation limits, on and on and on. Sensors are also programmable so you can run in STD shift or in GP shift, simply set it in the software and then do the needed physical modifications mechanically (typically flipping the shift knuckle).

Anyways, waaaay too long of a post. If you guys have questions, feel free to ask.

Regards,
Anthony

Yes... and no. Dynos are a great tool for sure, we use one here religiously setting up bikes specifically for customers needs/goals. But it is still just that, a tool. With the USB M v3 kit, you can tune it on the dyno yes, no problem. Additionally, you could tune without it via a standalone AFR gauge like an AEM UEGO but the problem is, trying to remember the AFR for every RPM range and that still won't help because you won't know the exact throttle position you were at. So is that scenario doable? Technically, yes, but very, very very difficult and nearly impossible to do.

Thats where the auto tune system comes into play. Typically most bikes like to see an average AFR based on it's setup, whether it's N/A or blown, under nitrous, etc. The auto tune does all of that for you. Now, it wouldn't be specific to any and all bikes as every bike is going to like to be tuned to a certain degree. But, say if the bike makes peak power at 12.9:1 AFR, if you have it tuned to say 13.2:1 via the auto tune, that .3 isn't going to account for a noticeable degree of change to the rider. Maybe a small inconspicuous bump on a dyno sheet, but on the butt dyno? Not noticeable.

I wasn't there as this was done in Australia by the Australian team (I'm the North American rep).
But based on historical data, weather conditions that day around that time were
82 Degrees, 59% humidity, 29.76" Hg, ~26' or so above sea level

I can probably ask Justin about about the conditions as reported from the dyno weather station if needed...
Nice. Can you find out what the Torque was?

Thankyou for the explanations. Looks a lot more technical than i had expected, i'd imagined just downloading a pre-made map and i'd be away. I understand it wouldn't be as perfect as getting it tuned on a dyno, but likely better than the standard map. Am still interested, but will find a local tuner first and see what they'd recommend. Many thanks
