ECU Tuning – Tune Files

I have a 2011 Kawasaki ZX10R. What all is done and what are the results of; Remove Factory Timing Retard and Throttle Restrictions, Increased Rev Limit, increase Top Speed Limiters? 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.

I have a 2007 yamaha R1 that is pretty much close to stock. I have slip-ons and a KN air filter. My question is, would i see any benefit from having my ecu reflashed being that my is bike pretty much stock? 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

If I have the ECU Tuning Service done do I also need a fuel control module like Power Commander or Bazzaz? No, You do not need a Piggy Back. The 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.

What are the dash codes? (Error codes) 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

Why adjust variable velocity stacks and what are the results or advantages of this? 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.

What results from adjusting “injector phasing?”  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.

What are “deceleration Maps”? What happens when you adjust or remove fuel injector shut off on deceleration? 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. We 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.

To use a Bazzaz Z-Fi control module, would I need to drill an extra O2 sensor for the exhaust for the stock ecu, or can I run the Bazzaz Z-Fi 02 sensor and the ECU will recognize it? In this case the Reflashed ECU will function the same as the stock ECU would. You will need to contact Bazzaz for further information and instruction on their equipment.

1) Would the reprogram sync with the Bazzaz Z-Fi without problems? Yes the Bazzaz Z-F1 will work with the 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.

Can my ECU be taken back to stock? “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)

My bike has an irritating jerkiness or delay with the on/off throttle at certain RPM. Can the ECU Service fix this problem?? 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.

I have seen big performance gains on literbikes but will this significantly help the performance of my 600? 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.

What is a Timing Retard Eliminator? what does it do? and what does the Tuning Technology do different? 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. We do 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.
