Pacific Northwest Premier Mobile Motorcycle Dyno Tuner


Not only are Yamaha’s the best looking bikes on the market but with proper engine management they can run pretty good too! Yamaha makes a very balanced engine but is also very neutered for emissions and sound regulations. Using secondary butterflys, air injection systems, rev limiters, fly by wire throttle and timing retards, they limit their machines. Adjusting all of these parameters can make your hot looking show bike run track worthy.

ECUnleashed provides a tune flash for most all Yamaha models, unleashing the engine to its true capabilities and potential, how Yamaha designed it. We are seeing upwards of 20hp to the tire with a light weight hi flowing exhaust and ECUnleashed. Balancing the fueling and unrestricting the fly by wire is the biggest key to get these bikes to run great.

ECUnleashed, PowerCommander, YEC, clones and Bazzaz are all great devices that we can tune and get your Yamaha to run its best. This applies to all Vstar, Raider, Stratoliner, YZF, R6,Rr1, 600cc and 1000cc make and models.

The2009 and newer R1 is the flagship tune for ECUnleashed creating 2500rpms of more usable power a minimum of 8hp down low and upwards of 20hp at the top end. Engine management systems and tuning truly transforms this motorcycle. All ECUnleashed and tuning can be completed in house on all engine management systems available.

  4. I recently bought a 11′ R1. First owner had it in your shop to be tuned. Are you able to look up what was performed and the performance gains?
    I’d like to bring it back in for an ECU flash and tune after I install a full exhaust.

    I have a 2011 r1. I’m about to put a bazzaz on it, it allready has race baffles, a k&n race filter, and the nos kit is on the way. Will flashing the ecu make any added difference? Also, after I install a cat eliminator I would like to have the bike ran on a dyno and a map for nos and a map for clean written.(if that makes sense) do you do this sort of thing?

        June 12, 2014 at 5:00 AM

      • You need an O2 sensor to test the air fuel ratio coming out of the exhaust, get it to 13.4:1 across the board and you’re set.

    Hello, I have a 2012 Yamaha Raider with LA Choppers Wicked Curve exhaust, PR Hi-Flow Air Kit, PCV w/autotune. Is it best to do an ecu reflash or dyno tune, or both? Which one gives better results?

    June 18, 2014 at 9:59 AM

    • Well they’re addressing different things. The PCV w Autotune is only taking care of your fueling. While the ecu reflash, does all of the fueling the PCV is doing, plus ignition timing tables, disables any power restrictions etc inside the ecu that the PCV doesnt touch. Basically everything the ECU controls, we optimize with the ECU flash, the performance mapping is done on the dyno so that is included. So the PCV is like a slice of the performance pie, and the flash is the whole thing!

    Got the ecu back last week and went for a 4 day 1900km ride through the mountains and what a difference, I had you make the bike start in std mode but A mode is so smooth and responsive the bike could start there, no problem. (When I first had my ecu done here in Australia by ecunleashed it was shit, as well as expensive! It had more power but the power came on at 4500rpm and 7000rpm so abruptly it was un-rideable but now it is a gem) That midrange is so good that in the tight stuff all you need is 3rd and 4th gear! To anyone who owns a mt09 (fz09) and is thinking who to send your ecu to, send it to Nels first.
    Great job

    I have a 2015 FZ09 I want to put on a Arrow X Kone full system
    Will a re flash allow it to work without buying a fuel controller?
    Will it work ok baffle in or out?
    Will it require air block off plates?
    Work with KN air filter?
    What will cost be? Sorry for so many question. I am 65. I can do carburetors ha ha

    December 26, 2014 at 5:28 AM

    • Yes we include fuel in the flash. Baffle in or out is your call, we flash for it in or out so just let us know what you want. Does not require block off plates but its recommended. Filter is fine stock r aftermarket. We love questions no worries there. Shoot me an email at and we can go over anything in detail with you

      December 26, 2014 at 5:17 PM

  21. Scott

    Get the block off plates, I did and have a my ecu flashed. He will make custom maps for your bike. When doing a full system, with K&N filter you will want block off plates.

    December 26, 2014 at 5:48 PM

    • The flash will deactivate that system anyway so you can remove it, put the block off plates on and save a few pounds.

      December 29, 2014 at 1:52 PM

  22. Scott mears

    I understand you do the Stoltec flashes for the Yamaha FZ09. I would like to know what that service costs if I were to send my ECU to you.

    Hey Nels I have a Yamaha banshee with exhaust, and ported cylinders. Iv read that you have experience tuning quads with carbs. I have had tuning problems ever since I had my bike ported and was wondering if you still tune quads at all? I also have a 06 R6 with full Leo vince exhaust, power commander, race filter that I would like reflashed. Hope to hear back from you.

    I have an 07 R6. I put a pcv on it and the throttle position is way off. it starts out at 17 and goes up to 49. I know its supposed to go from 18 to 98. its only does it when the pcv is hooked up. do I need to send in the ecu to get flashed?

    April 30, 2015 at 6:16 PM

    • Give me a call at 425-269-5332 it may be something that we can fix easily.

    Hi, I have an 2007 R6 and I pull on a full exhaust with a power commander v and an auto tuner. My bike is not running right. After it warms up and I get to the first stop light/sign it dies. I’m just wondering if I should get the ECU flashed or take it to a shop and see if they can get it to work.

    May 10, 2015 at 9:09 PM

    • It would be good to test the pcv and auto tuner as they might be causing it as well have you tried starting the bike with those disconnected?

      May 14, 2015 at 3:29 PM

  27. Randy

    Any plans to flash the new R3?

    May 31, 2015 at 9:05 AM

      July 28, 2015 at 12:36 PM

  30. steve

    Thank you for reply. What basic parameters are changed by the flash besides speed limiter. Just for my info to understand what to look for after the change and to help spread the word for your product. Looks like I know what to ask Santa for during the winter. I kinda like it stock so far but I definitely didn’t like my bike falling on it’s face at a buck 15.

    July 28, 2015 at 2:15 PM

    • As listed on the website, we change almost everything that can be changed. Fuel, timing, restriction removal, reduced engine braking, speed limiter removal, fans on earlier, disable exup and ais systems, fix speedo calibration etc

      August 10, 2015 at 10:03 AM

  31. steve

    So what your reply is saying; is that what’s being done to the Yamaha FJ-09. Or your reply is for what can be done? Does the flash cover the FZ-09 and the FJ-09 with the exact same changes? Or would the standard flash be set up for with the parameters differently for each type of bike. The FZ being a naked Hot Rod and the FJ being Sport/Touring Adventure type bike. I just read today in an issue of Cycle Worlds Long Term ride return to Manf. article, that Yamaha gave notice to all 2014 and older FZ’s that a free updated flash with parameter fixes from the FJ is available. I will reread the article to see if there is a mention of FZ program updated with FJ parameters or replaced with FJ program.
    Overall I’m happy with the performance of the Factory settings on the FJ. I want for example the same separation with the modes of operation. Don’t want to turn STD into A mode parameters, etc.. Definitely need the flash to remove speed limiter. Kinda worried that it may change my Sport Touring bike into more Hot Rod then is wanted for a loaded bike on a trip. I’m an older guy and not an ECU tweeker with a PC kind of guy. But I could set your Ignition points on a Z1 Kaw. Ha Ha. I do have a Laptop and could with assistance perform basic changes with phone instruction. I’m sure your turn around flash and flash updates are great but something may show up on the road test. I finding hard to give it up during the riding season as I ride 7 days a week mostly so I find it hard to not ride when the bike is basically running Ok. Do you have tech services, even for a charge, for offsite change support? Well I’ve bothered you enough Mr. 2wheel. I will send in the ECU for flash during down time this winter. Maybe we’ll get a Snow / Ice storm here in Va so I can leave it alone for a couple of days.
    Thanks, Steve

    Hi, I just bought a ’12 fz1 with full Yosh exhaust, pc5 and ais block off, already dyno tuned by you. I’ve been looking at what some other people have done and I’m wondering if you’ve had any experience with modified or removed secondary plates, I’ve read a lot of conflicting info. Do you recommend these mods? will this help or hurt drivability with another dyno tune?

    January 19, 2016 at 3:36 PM

    I have a 2015 yzf r3 that I recently put a full system m4 exhaust kit on and am running it without the arrestor/baffle. I have noticed a bit more power but not what I expected and I am experiencing some backfiring when down shifting and letting off the throttle. I have been told that I can either spend a bunch of money for components to add on the injectors and ecu to allow me to tune it or I can send off the ecu to get flashed with an appropriate tune. I would prefer to just flash the ecu if that is available for this bike, do you guys offer anything for this or have any leads?

    February 23, 2016 at 7:48 AM
