2 Wheel Dynoworks support or the easiest way to lost your $400

[ogri]

Short: 
2 WDW cares only about getting money and will screw you if you are complaining.
Long:
 I sent my 2015 FZ-07 ECU to "2 Wheel Dynoworks Inc". I was excited waiting for freshly re-programmed ECU. Fist ride - "Oh man, it is buttery smooth!". After some real-world riding, I realized there are some issues pop up after ECU re-flashing, it was summertime and because 2WDW lowered kicks-in temperature of a cooling fan, my bike became totally uncomfortable to ride in heavy stop-an-go-traffic, my legs start to melt and fries. The fan started kick-in and out every couple minutes while I was standing between traffic lights. They refuse to return fan T range settings without returning deceleration cut.

The biggest issue I noticed a couple of weeks later, the bike after ref-lashing got dangerous lags in power between 3.5K RPM to 5K RPMs (which is my normal commuting RPMs). Then I had two close calls. First when the bike has the lag in the middle of exit from the round highway merge section. The second was when someone started to change its line towards my place in traffic and I have to speed up, these two seconds can cost me a life. I send an email to 2WDW they said the described problem is with my MAF and O2 sensors. Basically, they refused to re-flash ECU back to OEM flash and credit back my money in a first my request month later after order. This is why I ordered another original used ECU from eBay, replaced re-flashed one and all problems are gone the same day. 
Later, I played between these two ECUs and noticed what the original Yamaha factory's flash is much stronger in terms of power response, maybe a little bit more brutal but this only plays for better bike charisma instead of having anemic, lagging but the smooth engine.
If someone has Dyno in the Miami, Ft. Lauderdale area, I can bring both ECU (re-flashed and OEM) and we can compare real graphs. 
My strong belief is what couple guys playing with dyno and pretending to be a "real" mechanics in their garage can't be smarter than a hundred engineers working at the Yamaha factory.

Yikes, sorry to hear things didn't work out for you, but many, many tuners and builders and riders on this forum have been very happy with 2WDW flashes - me included.

They also have seemed to be very customer-sensitive, so your incident is indeed a unique one from what I've read and dealt with first hand - they have flashed my ECU 3 times, with differing states of tune.

I know they will flash to a "stock bike condition," but with their version of optimized stock (no aftermarket upgrades).

But I disagree with the concept of Yamaha engineers - they have quite a lot of limitations and barriers to making the best power and throttle response. Theirs is a balancing act, and many times get it wrong, or the "best they could do" under the sound/emissions regulations and corporate pressures. This is a fact, I'm afraid, and the reason why there are soooo many aftermarket upgrades for ECU flashes and PCV and all the others. I am a mechanical engineer with quite a few years under the yoke of "corporate misdirection" to speak of.

Again, sorry it didn't work out for you, but yours is the first I've read about.

Good luck.

[sorkyah]

Sorry to hear about this experience, perhaps @2wheeldynoworks could weigh in here? 
I personally have the 2wdw flash, and havent had many issues. i have had a bit of decel popping, but that's mostly because of me being stupid and just cutting throttle from near 100% at (well over) highway speeds in 3rd/4th gear with a yoshi pipe that had only been repacked once in the 30k miles ive owned it. 

I otherwise have had nothing except good service from them in the two flashes ive had done and direct communication is always very responsive. 

[FZ07R WaNaB]

I have a 2016 with 8,000 miles on my flash from 2WDW. It was flashed for a stock exhaust with the snorkel removed. I have had absolutely zero (0) issues with my FZ since the flash with the exception that it runs great!

[2wheeldynoworks]

We're certainly sorry to hear about the OP's frustrations and experience. To clear up some misinformation here, I'd first like to say that we have never, and will never, refuse to flash an ECU back to stock. Furthermore, once an ECU is flashed, an FTECU tuning license is locked into the ECU at our expense, and this cannot be undone, which is why a full refund simply won't ever be possible. That said, we are always happy to assist in troubleshooting issues in any way that we can, whether or not they're related to our ECU flashing service. We're not just mechanics in a garage. We're motorcycle performance enthusiasts, and our 5 man staff, 3 in house dynos, full service and parts departments, and Nels' 20 years of tuning experience are always at our customer's disposal. We want all motorcycles that we perform any service or upgrades on to be better than before we touched it, so let's see if we can help by dissecting the facts a bit here!

If you only began to notice issues weeks after you received your reflashed ECU, then it is almost impossible that the issue is with the fuel or ignition mapping. You would have noticed an immediate issue if that were the case. That an issue arose after the fact would suggest that something else has failed electronically, or is in the process of failing, on the bike. O2 sensors and IAP sensors are common failures that we have seen several times on these bikes and cause similar issues. It is also very possible that the ECU could have become corrupted during the flashing process. It is rare, but it does happen on occasion as the FTECU software is NOT perfect. 

We keep a test bike for every model we support in our shop to troubleshoot issues exactly like this, so the next best step from a diagnostic standpoint would be to have the OP send us back the ECU so we can install it in our test bike and run it on the dyno to get some accurate hp/torque and AFR numbers. If there's an issue with the mapping, then it will be very obvious with this information. If not, then we can assist in helping the OP further diagnose the issue with their bike. 

It is also worth noting that if ANY of the input sensors on the bike (O2, TPS, IAP, etc) are beginning to fail, then a stock ECU (or an ECU with stock mapping) may absolutely perform differently, or better, than an ECU with our custom mapping! The inputs are simply voltage references into an algorithm, and the mapping we adjust are tables that the algorithm references. In layman's terms, the algorithm acts like a simple "If/Then" logic circuit, so IF a "bad" input is given from a sensor, THEN it will also be referencing an inappropriate portion of our custom mapping. That portion of the mapping in the stock ECU may cause the bike to respond much differently with an incorrect input!

To summarize, we're always happy to help, and we'd urge the OP to send us back their ECU for testing and to reach out to us directly. If anyone ever has any questions about ECU flashing, performance modifications, or just these bikes on general, never hesitate to shoot us a message or give us a call! We are always happy to help.

Unhappy also.  Tune wasn’t good and I added the activtune for an additional cost. Got the bike running better.  Later learned there are options for learning modes and other adjustments.  I never got any license numbers and was told I’d could take my bike out of service again and ship it back to them for my license number.  I can’t do any changes or anything and wish I would have just bought the cable and license myself from Flashtune for the same price and then I could work with it.

I don't think there is an actual license number.  But, your ecu is now licensed by ftecu in that their software recognizes that its registered and will allow remapping by anyone that accesses it with their software.  This means you can take your bike to a local tuner and they can remap it without paying the $100 registration fee.  I hope I am making sense.  Or maybe I am wrong.

There is always a tuning license that is locked into the ECU and only accessible by the FTECU account holder than originally flashed the ECU. This is done by FTECU for two reasons. The first reason is to make sure that everyone using their software has to pay for the $100 retail tuning license, no matter what! That is simply how they afford to continue offering us great tuning software. The second reason is for the protection of intellectual property for professional tuners, like us. 

Anyone can figure out how to dial in fuel mapping with an Active Tune and a little bit of research, but a huge percentage of throttle response improvements and overall performance increases don't come from fuel mapping alone. The ignition timing mapping that we customize for each bike and intake/exhaust system is just as important, if not more so, than the custom fuel mapping! There is no system that can be installed on most bikes to determine whether or not your ignition timing changes are having a beneficial or adverse effect on your bike's performance. This can only be seen and measured on a dyno!

We won't ever release our custom mapping for anyone to ever play with themselves, because we simply don't want any part in someone grenading their engine. After 110,000 passes on our main dyno, we have experienced exactly ZERO tuning related failures. A single degree of additional ignition advance across peak torque, paired with a lean condition, can cause detonation and send your conn rod straight through the side of the engine case. There's horror stories just like that on these forums from people getting "email tunes" from inexperienced "tuners" and riders playing with the mapping themselves. 

We will happily create a secured FT file for any of our current or future customers for less than the cost of our Mail-In ECU Flash for anyone that wants to use an Active Tune and accept the few % fuel trims that you'll see between each specific bike with our custom mapping, but the fuel mapping, ignition mapping and rev limiter parameters will be invisible and unmodifiable (besides using an Active Tune system) to the user of the file. We understand that enthusiasts often like to tinker with their bikes, because we do too, but for both the protection of our intellectual property and the protection of our reputation, we'll never release the raw map data for manipulation once our license is attached to it. Engines are expensive, we've never had to buy a new one, and we don't plan on starting anytime soon

I understand completely.  Thanks for taking the time to discuss this. 

I purchased the bike side ftecu for my bike a couple  years ago and uploaded power commander fuel maps.  I did not touch the timing maps.  I plan on taking my bike to a tuner who has ftecu tuning experience.  I assumed the tuner would be able to access my maps and make adjustments without another licensing fee.  Is that correct?   Thanks.  I'm a fan of your work through Marcel Irnie's videos and my buddy has your mail-in tune.

Awesome! No problem at all.

You'll need to either have the tuner login with your FTECU credentials when tuning the bike OR transfer the license number to his FTECU account and then have him transfer it back to you. This can be done on the FTECU site under the Licenses tab. Simply click on the license number, and you'll see an option to transfer it to another FTECU account/user.

Feel free to give us a shout directly if you have any questions about the tuning specifics when you get to that point!

There is.

 

[HulkHogan]

That is correct, each license is for one ECU.  And the license that was put on my ECU is mine.  These licenses are purchased by resellers in bulk.  I understand that I made the mistake of not buying the cable and the file, but when I had my ECU flashed I should have gotten my license number with my receipt.  There's no reason I shouldn't have gotten it as I paid one of these licenses.  Now there's no record of my license number by 2W.

And my flash was rich to the point where I knew I had no choice but to toss the activetune on.  Either that or call and hear that thousands of bikes have been tested just fine!

I don't want to come across as harsh, but again, this is not correct. Anyone purchasing our ECU Flashing Service, whether in our shop or online, is purchasing the end result of 20 years of tuning experience, over 110,000 dyno passes, and countless hours of R&D. You aren't purchasing unrestricted access to our proprietary intellectual property. Even the software manufacturers (FTECU, Woolich, etc) don't have access to this information when we use their software to flash ECUs and create our custom mapping!

Also, if you have an FTECU account and the necessary hardware, you can retrieve the license number out of the ECU yourself without issue. Where you'll run into an issue is trying to access any of the information in the ECU. You will be prompted to overwrite all of the information in the ECU that is locked to OUR account via a license number, because you don't own that information. Again, you're purchasing a service and utilizing our expertise, not our raw intellectual property. You'll find that all reputible, professional tuners utilize this practice, as well as all of the major tuning software manufactures. Licenses keep them, and us, in business and able to assist the greater motorcycle performance community.

A better, and more humorous, way to say all of that might be this:

If you order a bucket of delicious Kentucky Fried Chicken, and you aren't happy with your chicken, you send it back so they can make it right for you! You don't ask for the Colonel's secret recipe to try to make it better yourself. We have the ability to troubleshoot the rare issue that we do have with an ECU on our own shop test bikes, so if you think there's an issue, send us an email or give us a call explaining the issue and then send us back the ECU so we can check it out. If there is an issue with our product, we will of course remedy it free of charge, just like any reputable business! As we have said hundreds of times and will continue to say forever, we're always happy to help.

I hope both the cold, hard facts and my KFC joke cleared up any confusion anyone has

P.S. If anyone would like to give tuning their own bike a shot and want to purchase a complete FTECU Active Tune and On-Bike or Bench Harness Kit, they're available at www.2wheeldynoworks.com cheaper than they are from FTECU directly

Why not just upload the associated timing maps also? Just interested to know, there are good improvements to be had.

What would be humorous is thinking that we didn't already go through this all on the phone and emails a couple years ago.   And you wouldn't remedy it free of charge.  Someone told me that this flash has been used by thousands and there must be something wrong on my end.  No, your company was not willing to help without more money.  I felt like I was trying to talk to a fence post.  Turns out the OP had a similar experience as expressed in his very first sentence.

Here's a humorous KFC joke:  10 packs of FTECU Licenses can be purchased for $800...2WDW sells you 1 of these 10 Licenses for $315.  JUST KIDDING!  JOKES ON YOU!  They keep your license in their account.

Those are the cold hard facts.  Folks, you have been warned.  Best of luck to all.

Not trying to take sides here but when you pay 2wdw the money you are paying them to reflash your ecu. Where does it say on there website that you are paying for any sort of license? Youre paying for the mail in service

[blackout]

I understand what 2WDW is doing.  They are being smart and protecting their investment.  They have spent years and hours mapping bikes to run the best.  If they gave you the license number, you could access your ECU and steal their map for others to have for free.

This KFC reference pretty much says it all.... I found it both humorous, and informational.  I'm still learning about ECU flashing, as I've always gone the PCV route. I'm considering getting my ECU flashed and ditching the PCV. Let's face it, most of us regular Joe's don't know how to tune our bikes. I used to have "autotune" hooked up to my PVC, even that seemed to daunting to use? I pulled the autotune, and found a PVC map I liked. After many hours of trying do-it-myself, I've learned it's much easier to $$$$ for knowledge & experience-

I am with you. I know I am not anywhere close to knowing what to do so I went the Flash/Active Tune route. I installed the Active Tune this winter so looking forward to using it here in the spring!

Hordpower does the same, I think it falls under "Proprietary information" that has taken years of experience and countless hours working for nothing while investing a ton on the tools and equipment need to get to that point.

Same thing when you have a problem with your house, you think the rate is way too much, but your not just paying for the time spent on your house, it's the years of experience, the expensive tools on hand to be more efficient at remedying your problem. The ability to get hold of other licensed trades if they encounter another issue while getting to the bottom of said problem at a touch of the phone. This on top of paying to be licensed and insured. No 401K options, no medical insurance or dental included.

Sure they could tell you how to do it, and stand there and give you instructions, let you you use their tools and point you in the right direction by advising you with their knowledge, hell even use their license and insurance and contacts, Charge you the same rate, a now 1 week job has become a 6 week job that you have to cover the cost of. Do the math.  You must also consider that when they go home they have pay roll and suppliers to deal with. Sometimes the contractor doesn't get paid in full, the subs and suppliers do. All of this has to be taken into consideration, if it's something your not willing to cough for, feel free to Do It Yourself. Just check with your local Buildings/Planning Department before you proceed. BTW (up to code ) is the bare minimum accepted, uugghh.

All of this is relative to the KFC reference also.

There is advantage to piggyback. You can go anywhere on dyno to tune bike or change map. You actually tune your own bike not some other bike. If something goes wrong you just unplug it and run without it.

 

[wollerms]

My experience, I sent 2WDW the ECU's from my 19 MT07 and my 17 SV650 during their thanksgiving sale.  I'm very happy with both reflashes to match my aftermarket exhausts. They received them and turned them around back to me in short order.  I used to go the PCV route but was having trouble finding a good dyno shop and going w/autotune seemed pricey. I'm sticking with 2WDW.

In my first complain I said bike is too hot to became uncomfortable, you answer was 'it is not possible, we injected more fuel and made your engine cooler.'

Then I asked 2WDW, I wish to return fan temperatures back to stock and leave decel cut removal in place, you said we can't return temperature only it is dangerous for engine we have to return all setting back to stock. Obvious reaction was if you returning ECU back to stock - return money too, you did sold me nothing.

I noticed mentioned lag in the power weeks later because, as mention earlier, it is appears ONLY in specific narrow range of RPMs within situations when you cruising/decelerating and have to brutal accelerate immediately. I am not riding aggresive most of the time (my FZ has 30,000 pure city miles), these situations are not happen every ride and can pops up only weeks/months later.

What you are saying about possibility of the corrupting ECU is scaring a bit, are you checking the flash consistence/CRC/hash? you are testing ECU with real engine/bike after re-flash? This kind of software errors can lead to someones death if he/she will lost engine response overtaking truck at 75 mph on a busy highway for example. Your support team pointed me to "some failing sensors" - doesn't make any sense because factory's ECU do not affected by these "phantom errors" or can ignore them in a complete safe way in my case. I switched to the OEM ECU three months ago and never experienced any lags after. I have them come back after connecting re-flashed by 2WDW ECU again.

To summarize, we're always happy to help, and we'd urge the OP to send us back their ECU for testing and to reach out to us directly. If anyone ever has any questions about ECU flashing, performance modifications, or just these bikes on general, never hesitate to shoot us a message or give us a call! We are always happy to help.

If the reality is like you are telling here, I will be happy to send my 'bad' ECU for the health checkup. If we are dealing with data corruption, you will fix it and we transparently for public will close the 'case' here.
