ECU Tuning – Tune Files

There are internal maps inside of the factory ECU that control everything on your motorcycle. These include fuel, ignition, idle, rev limit, deceleration, and many many more. We use our hardware and software to adjust or remap each of these parameters and optimize the overall performance of the motorcycle. Due to emission and sound regulations the factory are forced to restrict the motorcycles to suite these regulations. The 2011 ZX10R in particular is one of the most restricted motorcycle we have seen to date. It is not only restricted at the throttle plates but it also has ignition timing retard and top end limiter. We have adjusted and optimized each of these parameters by remapping them inside of the ECU. We have developed an incredible tune file that results in an 15-20+ HP gain (potentially more on a bike with mods), and a top speed of 199 mph on stock gearing.

Absolutely !! Not only will you see and feel a significant increase in power but the ECU service will also smooth out the power curve and make the bike much smoother and consistent. Normally on a 2007-08 Yamaha R1 you will see an additional 4-5 hp at peak and 7.5 hp above 11500 RPM. Just as important as the increased power is the smooth performance the bike offers after we are done. We fix the on/off throttle inconsistency issues that are often found in the Yamaha’s and one of the 07-08 R1 major problems. We work with most of the parameters inside of the ECU including fuel and ignition maps, deceleration maps (engine braking), rev limit, dwell timing, throttle maps and more and because of our ability to work with all of these parameters we are able to produce a Tune File that not only increases power but also makes the bike easier and more predictable to ride. The new throttle maps, fuel and ignition maps make he on/off throttle much smoother, and the improve deceleration maps (engine braking) help smooth out corner entry and makes it much more consistent and predictable. Overall it will make this bike an entirely different motorcycle to ride.

Technical Information

No, You do not need a Piggy Back. The ECUnleashed service optimizes each of the parameters inside your ECU delivering an excellent overall tune with maximum performance. Because of this your vehicle will not require an additional Fuel Control Module. However some find adding a “piggy back” for specific conditions such as different Track Type, Fuel Type, Atmospheric & Elevation Levels. This should be done ON A DYNO With a professional Tuner.

The dash codes we are referring to are the error codes that are the ECU will display on the dash after performing certain modifications like……… * removing the exhaust servo motor * O2 sensors * steering dampers * pair valve AIS system

On vehicles equipped with variable velocity stacks, we are able to adjust and optimize the times in which the stacks lengthen and shorten according to the characteristics and variables of the motor. The results can offer improved performance, shifting the power curve or increasing power in a particular area of the curve and lastly reducing the sometimes abrupt disruption in power at the point the velocities perform the switch from long to short and vise-versa.

In basic terms, overall adjusting (increase or decrease) the pulse widths and timing in which the fuel injectors deliver fuel to the motor. The basic purpose for adjusting these parameters is simply to fine tune and match the proper timing in which fuel is delivered (or not)to the cylinders in a manner that optimizes the overall power and ride-ability of the vehicle. This phasing will vary per vehicle/motor/conditions, however it is another variable that when adjusted to an optimum state, it can improve the overall performance and efficiency of your motorcycle.

On most of today’s modern fuel injected sport bikes, the factory shuts the fuel injectors off immediately when the rider lets off of the throttle. They do this, to lower emissions on the vehicle and justify this by saying, fuel is only needed to accelerate. However when the fuel injectors are shut off and stop delivering fuel in such an abrupt method the results are normally not very good on ride-ability. 2 of the main problems that result from this are (1)The bike will have a very choppy on/off throttle control which not only makes for a “jerky” feeling under normal riding conditions but will also significantly upset the chassis during corner entry, corner corrections, and corner exits. What we at ECUnleashed take the time to improve and adjust these deceleration maps that slowly and consistently ramp the fuel down as you let of the throttle making for a smooth and predictable deceleration and/or on/off throttle control. The deceleration can improve track times as much if not more than a quality fuel map. High speed corner entry becomes very smooth and less violent helping the suspension geometry work for the rider instead of against, mid corner throttle corrections are now very linear with reduced ON/OFF throttle jerk, and corner exit is consistent because the fuel is down being increased and decreased in a very linear and cohesive manner.

Yes the Bazzaz Z-F1 will work with the ECUnleashed reflash. It will function just as it would with the stock ECU … HOWEVER…. due to the many changes and improvements we make to the internal mapping parameters inside the ECU, we strongly suggest not running the Bazzaz Unit until you can have a quality fuel map built by a credible tuner. Until you can get this custom map completed we suggest either removing the bazzaz unit or at least ZERO mapping the unit. The ECU will work excellent by itself and once you get to a quality tuner, they will be able to fine tune in the subtle improvements to the fuel map through the Bazzaz.

“Return to Stock” Option allows us to return your ECU back to it’s stock settings, maps and parameters at anytime. (fee’s will apply)

In each of the ECU parameters (Fuel, Ignition, etc) we have the ability to tune each maps, in each gear, at each RPM. We develop our Tune Files not only for maximum power increase but we also significantly smooth out the power/torque curves making the bike more consistent feeling. This helps a ton with the jerky on/off throttle that is notorious in most modern sportbikes. It helps eliminate upsetting the chassis during mid corner throttle corrections, while also assisting in corner entry and exit. We also work on the deceleration maps which considerably helps corner entry. It reduces the amount of engine braking that comes on when decelerating for a corner.

You will see a lot more overall power from the reflash on a larger bore bike….. however the reflash is very effective on a 600 simply because not only will you see added power on the top end (3-6hp normally) but you will usually pick up 2-4hp throughout the lower parts of the power band and that is so important on the 600′s. Also due to the fact that we tune the maps in each gear, each RPM, we significantly smooth out the power curve and it helps a ton with the jerky on/off throttle that is notorious in the 600′s. It helps eliminate upsetting the chassis during mid corner throttle corrections. We also work on the deceleration maps which help a ton on corner entry. It reduces the amount of engine braking comes on when decelerating for a corner. Overall the reflash will help the 600. You will not see as much over all power gains as the 1000 but if you ride the track you understand that smooth consistent ride-ability is as important if not more important than overall peak horsepower.

Many of today’s sportbikes, mostly Suzuki and Kawasaki models, are restricted in he lower gears by retarding the factory ignition timing. The purpose of a “Timing Retard Eliminator” is to “trick” the ECU into thinking the bike is always in it’s optimum gear (usually this is 5th gear). Optimum gear has no timing retard, no restrictions and no top end limit. HOWEVER what people do not realize is that if you are “tricking” the ECU into thinking it is always in 5th than you are also telling the ECU to use all of the other 5th gear maps like fuel, ignition, injector, deceleration maps etc. The ECU has individual maps developed for each gear (fuel, ignition etc etc) and to tune the bike correctly you need to address each parameter in each gear. ECUnleashed Tuning Technology does things a little different. We remove the timing retard, restrictions and top end limiters in each gear, but we do so while still tuning each individual gear and allowing the bike to use those parameter maps appropriately. No “tricking”, but instead fixing the issue at the source and tuning the bike properly.

Distribution – Dealers

In the interest of our Authorized Dealer network, we have implemented Distribution Policies and Requirements that we feel will ensure growth and longevity with our partners and retain the highest level of product and service we can offer: Our goal is to set a limited amount of ECUnleashed Authorized Tuning Centers per state/country (Most States will only have 1-3) depending on the amount of consumer market share there is in that region. We will avoid servicing retail customers directly. We will offer the retail public technical assistance and product information but will forward all sales and service inquiries to our Authorized Tuning Center in that state/region/country. We do however leave the option open to service retail customers that do not have an Authorized Dealer in their state and/or are not receiving the proper customer service from that Dealer.

Dealer Requirements: 1. The Dealer must be a legal company, dealing prominently in the motorsports industry. 2. Dealer must have a retail facility and should have a Vehicle Dyno and the knowledge and ability to tune customer vehicles. We are looking for Motorsports tuning companies “tuning shops”, NOT retails distribution companies who only serve customers through their websites. 3. Authorized Dealer must purchase our Serial Suite Tuning Kit giving them the ability to select our performance Tune Files and reprogram or “Flash” them into their customer’s 4. Authorized Dealers must meet requirements to be able to use the Serial Suite Kit which include Internet connection, Windows based computer (preferably XP), a reliable 110v circuit (plug), intermediate computer knowledge. 5. Dealers are expected to advertise and promote the ECU service to the consumer market in their territory through the various media outlet(s) (website, forums, publications etc). These are our basic requirements and what we feel will offer us strong, long lasting, and successful partnerships while delivering the highest level of product and service to our customers.
