RAPID BIKE EVO MODULE:

The Rapid Bike Evo module enables you to take total control of fuelling operations, as it directly connects to all fuel injectors and also works in conjunction with the bike's standard O2 sensor to constantly manage the air/fuel ratio.  

The Evo module’s most important benefit is the Auto-Adaptive feature, the ability to correct automatically the injection map by reading the signal of the stock O2 sensor (Lambda) while riding the bike. The injection map then becomes a dynamic value in order to match the changing weather conditions and driving style.

As the Evo module works with the O2 sensor, rather than eliminating it, the Evo module can adjust the entire fuel map including the closed loop area, something which some other fuelling modules cannot do.

Each Evo kit comes with the universal Evo module loaded with the correct map and settings for the CRF1100 Africa Twin and the bike specific wiring harness which features O.E. connectors for a simple plug and play installation. 

Innovative Auto-Adaptive feature – No need for a bespoke map or rolling road set up

The new and innovative auto-adaptive feature allows the Rapid Bike module to compare the air/fuel ratio target value with the signal reported by the lambda sensor. The result of this continuous comparison determines whether the fuel being injected needs to be increased or decreased, and ensure the engine always delivers its best performance.

This advantage is even more useful when making modifications to your CRF1100 Africa Twin such as the installation of a performance air filter or racing exhaust system requiring the injection map to be modified. Rapid bike is able to re-map, develop and implement these changes automatically whilst the rider is using the bike, there is no need for further intervention - it is true auto-adaptive technology. Other atmospheric factors such as temperature, pressure and humidity are also constantly being modulated and auto tuned.

RAPID BIKE EVO TAKES THE BEST OUT OF YOUR BIKE!

Rapid Bike EVO supports quick shifter sensor (optional),multiple maps management, raising RPM limiter (up to 1000 rpm) and the elimination of speed limiter.
For twin cylinders engine equipped with double lambda sensors, it is possible to develop a specific injection map as well as an auto-injection remapping set specific for each cylinder.

Installing YouTune controller allows to enable and manage additional features:

• REAL TIME MANAGEMENT of additional functions such as modulation of auto-adaptive target for air/fuel ratio calibration, fine tuning of engine braking effects, full customization of quick-shifting, while also displaying a number of engine operating parameters
• ENGINE BRAKE managed while decelerating to prevent rear wheel jumping and improve the bike’s stability while bending
• RPM CONTROL ACTIVATION to maintain constant engine power delivery and cruise at smooth and comfortable pace

Summary:

• Able to fully control fuelling in both closed and open loop through every RPM.
• Auto-adaptive feature dynamically changes values so no rolling road required
• Base Map supplied with module which will self learn to give optimum fuelling within 200km (approx)
• Plug & Play - Comes with bike specific loom with OEM connectors 
• Supplied with comprehensive Installation Instructions - specific for the CRF1100 Africa Twin
• Supports optional: Quickshifter (sold seperately) 

TOTAL INJECTION CONTROL

Rapid Bike EVO takes the best out of your bike!

WE TAKE YOU STRAIGHT WHERE OTHERS CAN'T REACH! - PLUG & PLAY, AUTO LEARNING

Take a close look at the map values: all other brands of add-on modules claim to modify the injection values, but in reality Rapid Bike is the only one allowing you to take action and reach consistent results with re-mapping the most critical section of the power delivery curve, that is the range of low and medium rpm where the lambda sensor is in full control of fueling parameters.

The graph’ blue area is defined by other brands as ‘closed loop area’ and as a matter of fact this section remains ‘off-limits’ for the rider since no real modifications of injection values are allowed. Rapid Bike technology puts you in full control of the game without any sort of limitations, offering you a powerful tool to be in charge of improving your bike performance in every riding conditions.

RAPID BIKE REVOLUTION FOR LAMBDA SENSOR MANAGEMENT

Adopting electronic technology for engine management requires a number of sensors to control the amount of fuel being injected and maintain a balanced carburetion. The amount and quality of intake air coming through the engine and mixed with fuel is affected by different factors such as temperature, pressure and humidity rate: this is the reason why bike performance is likely to change considerably with unpleasant consequences for the rider.

LAMBDA SENSOR: WHY IT WAS CONSIDERED AS A PROBLEM

Stock lambda sensor measures the quantity of oxygen in the exhaust gases while OEM ECU (Engine Control Unit) determines the air fuel ratio (air quantity in proportion to one unit of gasoline) to compare it with the value pre-set in its memory and modify the related injection timing.

Bike manufacturers adopted the lambda sensor installed on the exhaust system to monitor the carburetion values in order to comply with increasingly restrictive anti-pollution regulations. This system represents a real constraint for engine performance as it is forced to run with very lean fuel mixture while causing lack of throttle response and sudden power gaps. Here is why lambda sensor is often perceived as a major problem preventing the engine from exploiting its full potential.

RAPID BIKE PROVIDES THE SOLUTION!

Rapid Bike technology is very simple, yet quite innovative since it takes advantage of stock lambda sensor to improve engine efficiency while optimizing fuel consumption.

The goal is not to eliminate stock lambda sensor, rather to perform a dynamic modulation of this signal in such a way to result fully compatible with new injection values set by the add-on module.

This solution helps the whole system (OEM ECU + Rapid Bike) to be more reliable, and to prevent benefits of improved fueling from being perceived as a mistake requiring a further correction. As a matter of fact, Rapid Bike add-on module changes the amount of injected fuel (as it controls directly up to 8 injectors) while modulating stock lambda sensor signal in such a way that OEM ECU will not detect any difference in the air fuel ratio.

Such an innovative solution puts ‘out of the game’ poor and inefficient attempts to eliminate stock lambda sensor signal with devices no longer useful for an efficient management of latest fuel injection technology.

AUTO-ADAPTIVE FEATURE: OUR EXCLUSIVITY

Rapid Bike additional advantage is the ability to stabilize the best fueling values reached with using the add-on module, a system which is similar to the ECU working criteria. The new and innovative autoadaptive feature allows Rapid Bike module to compare the air/fuel ratio target value (set within the module’s map) with the signal reported by the stock lambda sensor. The result of this continuous comparison determines whether the fuel being injected needs to be increased or decreased, and secure the engine always delivers the best performance.

FREE YOUR MIND FROM THE OLD MYTH OF A SET INJECTION MAP

This advantage is even more useful when performing some consistent modifications to the bike (such as the installation of a free-flow air filter or a racing exhaust system) requiring the injection map to be modified – Rapid Bike module is able to develop and implement these changes automatically, while the rider is using the bike.

Rapid Bike overcomes the “old” idea of an injection map conceived as a value remaining fixed overtime. Our add-on modules offer the unique feature to develop an injection map and keep it constantly adjusted making the proper modifications without any need of external operations. Such a technology is so far advanced that a Rapid Bike module will complete the auto-remapping injection process within 200 km ride even in case of starting with a ‘zero’ value map.

If you replace your stock silencer with an aftermarket one that does not have an exhaust valve built into the link pipe, will result in the engine warning light showing on the instrument panel, and could end up with your CRF1100 going into 'limp mode'. 

Plugging in a HealTech ES Eliminator will stop this from happening, allowing you to fit whatever choice of aftermarket silencer you want to your CRF1100 Africa Twin or CRF1100 Adventure Sport.

Exhaust Servo Eliminator (ESE)
Remove the bulky and heavy exhaust servo motor when replacing the end-can or the full exhaust system. Plus, it will get rid of the FI light coming up when disconnecting the servo motor. Get the job done right with the help of the tiny, but mighty ESE!

Awesome tech

• Built-in microprocessor ensures optimal function and offers great compatibility. Just plug it in and enjoy the ride!

Size champ

• The unit itself is almost smaller than the OEM connector it connects to.

Endless compatibility

• Works with all aftermarket slip-ons, full systems and even with the stock exhaust.
• OEM exhaust cans and systems won’t win a beauty contest these days (and rarely did they in the past), they weigh a lot more than the aftermarket counterparts, sound crap and you never reach the bike’s full potential with them. Whatever is the reason to change your end-can or whole system, removing the exhaust valve will leave you with the dreaded FI light. Install the ESE to take care of that so that the FI light will come on only when it has to – when there’s a trouble with the engine.

Regain useful space while shedding weight
This tiny little fella will eliminate the bulky, heavy and space wasting OEM servo motor with the operating cables and wiring, which can save up to 1 kg and frees up a lot of under seat storage. Also, you may now get rid of the exhaust valve too by replacing the exhaust system.

Awesome Tech
Built-in microprocessor ensures optimal function and offers great compatibility. If your bike is equipped with an exhaust servo, you’ll need an ESE module – either if you replace the exhaust system or add a fuel controller module (or both).

Plug ‘n Go install
All ESE models are Plug ‘n Go, installation is a breeze. Just locate the exhaust servo motor under the rider/passenger seat, disconnect the plugs, plug in the ESE to the OEM connector and that’s it, you’re ready for the ride!

What's an Exhaust Servo & EXUP valve?
For the last two decades bikes have been equipped with an exhaust flap valve (also called as EXUP valve) to improve low down torque with the hindering of the flow of escaping gasses creating back pressure in the exhaust system. As the revs rise and the more you open the throttle, this valve opens more and more so the gasses can leave unblocked. This valve and its housing is welded after the header’s downpipes right before the collector pipe and/or the collector chamber/catalytic converter so removing this alone from the factory system is not worth the time, the money and the effort itself since the OEM system in the most cases is still low quality and heavy as hell. Of course, titanium OEM systems exist but finding an exhaust shop with titanium welding capabilities isn’t easy and will cost you an arm and a leg in labour to remove the exhaust valve from the system. So it’s easier and gives much better result to opt for an aftermarket end-can or whole system. Either way you take, you will need an Exhaust Servo Eliminator to complete the job properly!
