The top speed of your motorcycle is somewhat digitally controlled, and this can be reset to some extent with tuning. One controversial area of flashing your engine control unit is that of RPM cutoffs. When flashing your ECU, consider balancing the amount of boost with preserving your engine. This piles on some overall stress to the engine, which can shorten its life. The downside of this is that it can add heat in your motorcycle cylinders. Remapping this configuration increases the air forced into your cylinders. The boost on an engine can also be increased with flashing the engine control unit. Remapping this portion of your engine control unit can increase power, believe it or not. However, to some extent, part of your horsepower can be sacrificed to make for better fuel economy on a motorized vehicle. Your fuel economy is generally more of a concern in vehicles than motorcycles, as motorcycles tend to get good gas mileage. Reprogramming the air and fuel ratio can help maximize power as well as thermal efficiency. This adjustment, when flashing, can get the timing of the fuel injection into a prime spot to prevent engine damage and maximize the energy created by your engine.Īs in automobiles, tuning your ECU can also improve your air and fuel ratio, in order words, your boost, governed in the engine. Tuning the fuel ignition can prevent your engine from knocking, which can destroy it more quickly than you would like if you care about your bike at all. If they go to late, vital energy can be wasted. When spark plugs fire too quickly, they go against what the engine is attempting to do. Spark plugs must wait for the timing to be fired at the crucial moments. The exhaust-valve control cannot be deactivated.With your ignition, the cylinder for your piston fills with a combination of air and fuel during your motorcycle’s compression stroke. There is no possibility to deactivate or modify the parameters of the Lambda probe. Therefore the increased rev range is not mapped to attain optimal performance. These parameters are copied from the rev limit of the original map into the inreased range. When increasing the rev limiter by means of an auxiliary module it is not possible to redefine the fuelling, which can lead to fuelling problems and preignition. Thus 100% optimal mapping is not attainable.Īn influencing control on injection timing and Spark Advance in "real time" is not possible. This causes a timedelay (even if only milliseconds) between the signal receivers and the information received by the auxiliary module (injection nozzles, butterfly valve potentiometer, etc.). The auxiliary module is dependent on the signals that the original ECU receives. The installation of additional hardware means that there is more possible sources of error. With this approach the user must consider the following criteria:Ĭomplex installation at vehicles with lining. So far the most applied method for adjusting the fuelling map of a bike is the installation of an auxiliary module. The RexXer will deliver to you a smoother engine ,better throttle responce ,more Torque and Horspower, no more snatching at lower RPM and minimal popping of the exhaust if any on the overrun.|With some flash loads with the later model motorcycles we are also able to§ Personalise the digital interface of your dash on start up§ Switch off and remove the lambda sensors from the exhaust system§ Removal of the exhaust valve function§ In some instances increase the rev limiter The RexXer is designed to (give real time fuel and ignition control) No bolting on of a control box and wiring to regulate fuel control.
It is recommended to have a full sports exhaust system or aftermarket slip on mufflers and a high flow air filter to give the maximum performance. We are able to offer advice on a range of options that will enhance the flash to give you the best performance.
With this concept we simply plug into you’r own ECU and download the required map. It is the most economical way to improve you're performance. ECU flashing for motorcycles has now brought forward a whole new concept in engine management.
