A More Affordable Flash Option?

[avc8130]

Can you save or have you saved the various (-30, -70, etc) stock versions before doing the flash?

Can you return to stock an ECU unleashed flash?

Just curious as to what is possible.

Also, if you got hold of an ECU that has been flashed by ECU unleashed - can you save and look at their data? I gather this has not yet been done.

I have the following files in my arsenal: -30, -50 and -70. We are currently working to get -40.

I could return the ECU-U to stock, but why would you want to?

I, personally, cannot. I send ECUs straight to Flash Tune to extract the data that is on them. They x-ray the ECU and then have to cut it open to access the raw EEPROMs to extract the programming. To my knowledge an ECU-U ecu has not been hacked. Chris would never post the data, as I would not either, as it is proprietary and property of ECU-U. The data would be available to the owner of the ECU as a "backup" for them to base their further tuning on.

So getting the goods is not merely plugging in and extracting the data - I can see why no one has done it. Does the ECU end up destroyed in the process?

I had a similar product on my Harley made by TTS Mastertune where with their software and interface you plug into the bikes diagnostic port - first you save the factory settings for backup, select a base map and proceed with either autotune or dyno work to suit your mods and likes/dislikes. Pretty good system, lets you change all sorts of things, shame there's not a similar product outside HD models.

I think most haven't done it because it requires spending another $400 after the ECU-U flash, and I don't think the ECU-U flash is something most guys want to tune afterwards. Generally guys that buy a flash aren't interested in rolling their own.

"Destroyed?"

Heck no. Remember, Chris performs these cuts for a living. As I said, the ECU is x-rayed to make sure the cuts are in the proper location. Then the plastic is cut away and the files extracted. When complete, the ECU is filled with epoxy and painted again.

Here is my personal ECU post "hack":


Oh there are products like that outside of HD. Tune ECU can be used for KTM and Triumph. There were a few options for Buell. What it boils down to is that the big Japanese factories control their intellectual property a bit better. I have never heard of Yamaha flashing an ECU as a repair or update. In the Buell world, we would get new ECU programming almost as often as tires.

2 more ECU's flashed and on their way back yesterday, another flashed today and will be on its way back Monday.

Enjoy and ride safely!

Anybody else interested, now is the time. Spring is starting to pop up in some LUCKY parts of the country. I'm still doing my best to keep down time to a minimum (usually less than a week including shipping time).

If anyone is on the fence, don't be. I have only been able to put on about twenty miles since reinstalling my ECU but the difference is quite remarkable. The bike is now an absolute pleasure to ride. Good job Anthony.

 

[p51super10bombay]

I'm sort of on the fence, bike still has zero miles and is torn apart for powder coat - probably be about two weeks before I get the parts back is PC'r is going on vacation but the weather is crap anyway. Having only got one test ride under my belt - AVC, can you give a brief overview of your current version of the flash in each standard mode plus the CJM and maybe how this compares to the ECU version? My plans are only for some very light mods, I have a Akra slip on to install, will be keeping the stock paper air filter and might (again MIGHT) gut the stock header or install a catless arrow header. Mostly, I'll be happy if it runs well with no decel popping, lean conditions and the drive line lash (low rpm sloppiness) is gone.

P51, I think you are taking the problem the wrong way. Before doing any mod to your bike (related to the engine behavior that is), do the reflash. Any of the concerns you have regarding "with no decel popping, lean conditions and the drive line lash (low rpm sloppiness)" will be gone, if ever these issues have ever existed. How could you know since you have zero miles?
The S10 will evolve without any other mod but just the AVC reflash from a "good bike with frustrating engine" to one of the very best dual-sport in existence. And don't worry about being able to manage the power, you will find among the three maps available the right one for you .

Now, AVC is highlighting a potential issue coming. He is about to resume riding and enjoying his bike, hence less time to reflash other's. Don't be sorry because you can't get your flash done on-time after the riding season has started, do it now!

I guess I am carrying over what I came to expect on the Harley, make intake/exhaust mods and expect some sort of fueling mods to be a MUST, goes the same with removing the cat - very popular mod if only to rid the bike of the heat coming off the cat. As far as zero miles, I did take a test ride on one and the drive line lash was probably the things that I liked least. Also agreed to getting things done now - which is why I bought the bike in February and got right to making changes on it NOW so I can play when the weather gets better.

As far as ride-ability, NOTHING will do as much per dollar as flashing the ECU. My service, Diapson, ECU-U. It's your choice.

Yamaha did us no favors with the factory throttle mapping.

The main goal of my throttle mapping is SMOOTH, both on and off the throttle.

We have to realize that S and T modes in the factory map are just different levels of restriction to what the engine is capable of. T mode basically restricts MAX throttle to around 50-67% depending on gear. S mode is restricted in low rpm and max throttle is limited in gears 1-3. This makes the bike feel lethargic and silly for a 1200.

What most guys have selected is the following:
T: a straight and linear throttle. I remove a TAD of the engine braking to try to make it smoother on/off the throttle.
S: a more aggressive throttle map. The more you whick it, the more the engine whicks it. I remove more engine braking usually to make the bike charge corners hard.
SS: ridiculous in my opinion. This map is snappy and belligerent. Pretty silly for a 600lb ADV bike, but too many guys enjoy it to leave it out of the equation. This mode requires 91 octane.

All of this can be customized to a degree.

I've said it before and I'll say it again, looking back, this is the first thing I would invest in for this bike. Certainly wish I had done it sooner, no brainer if you haven't yet.

One of those two was mine!

Only problem is that I'm in one of those UNlucky parts of the country called Buffalo, NY - It's going back down below zero again tonight. You Canadians can have your polar vortex back anytime now!

I can't wait to see how much more fun this bike is going to be to ride now that I have a 1:1 throttle to butterfly again. Yamaha should have at least made one of the stock factory maps a 1:1.

I've only ridden the bike 7 miles but I knew that the neutered factory restrictions had to go as soon as I twisted the grip.

Anthony was great to work with and gave me what I asked for map-wise.

Thanks again!

Question for you ac, As I understand it the AF-1 ECU-Unleashed flash kicks up the Idle RPM to about 1200. Mine idles at about 800 (which seems too low). Question to you is what does it take to kick up the idle (manual, Fuel mapping, A 0 or 1 throttle setting?) I was reading about some of the S10 "non starting issues" and read from more than one now that had the AF-1 flash done has not had the non start issue repeat itself. Of course this could be pure coincidence but since the non start issue seems to be more of a flooding issue a higher idle couldn't hurt any (burn off fuel better before a cold engine is turned off). Don't mind me it's just cabin feeeva setting in again, More curious of what it takes to change Idle from a mapping standpoint. Thanks.

Lango,

I doubt changing the idle will help the hard to start issue. The ECU has an idle "map" which has higher idle during cold start. FZ-09 guys are starting to find the hard to start issues also. I think it is a "Yamaha" thing.

I don't have a direct means to adjust idle with the FT software.

Has anyone had hard to start since I've flashed their ECU?

Ac, don't mean to hi-jack, but just wondering if the hard start on the fz-09 is specifically on non-flashed units?

 

[Langolier]

Lango,

ac

Nope, not suggesting anything like that. It was just an arm chair observation that is usually a 2% chance of being correct. Is there any manual way of idle adjustment ?

 

[avc8130]

No idea. I'm just a casual observer on the FZ forums.

The Fz-09 hard start seems to be limited to California bikes, pulling the charcoal can seems to be the fix

I had a Buell that did that. The fuel vapor cans cause a vapor lock and a rich condition depending exactly how they are plumbed in. I know an FZ owner that complains of fuel smell. He does not have the vapor can.

I've never had the "hard to start" problem, unless I caused it on the Tenere.

Ok, Saturday we had a glimpse of sunshine and the mercury hit 47. That was enough for me to go test my ac8130 ECU reflash. I'm very happy with the results. In T mode (old S mode fixed) the bike runs much smoother in 1-3 and not as flat in 4-6. In S mode (secret recipe) the S10 definitely accelerates faster when twisting the right grip. You really notice it when cruising about 60mph/3K rpm in sixth Gear and go WOT to pass a four wheeler. It pulls much harder and no need to down shift.

More mileage will allow me to better explain the difference, but wanted to give some quick feedback. My S10 is basically stock other than the air filter. Forget the CJM and go this route.

The only problem I see is it makes my right wrist twitch which is causing permanent wrinkles around my mouth ::026:: this could result in more trips to the gas pump.

Happy in Ohio

A new shipping "guideline"!

PLEASE PLEASE PLEASE

DO NOT USE PADDED ENVELOPES ALONE!

I had an ECU arrive today with one of the female connectors damaged. Admittedly, it was packed pretty poorly. I was able to "repair" it with some Krazy Glue after advising the owner of what had occurred.

I have found the ECUs fit well in a small flat rate box. This is how I return them. I take care to package around the connector side. The non-connector parts of the ECU are a brick poop house.

Otherwise, a few more on their way to happy homes.
