WHAT DOES IT MEAN TO TUNE YOUR MOTORCYCLE? This guide will also not apply if you’ve changed your engine significantly (big bore, cams, headwork). First, let’s break down some basics to help you understand what a motorcycle tune is. So make sure that your bike is in good shape before you think about a tune. Many issues that are thought to be a tuning issue are actually maintenance issues. Before we get into it, we want to state that tuning your bike will be useless if your bike isn’t properly maintained. We’ve put together this basic guide as a starting point resource to find out what a proper tune can do for you, when you will need to tune your Triumph depending on your model and modifications, and also give you general parameters of methods of tunes to use as applicable to aftermarket performance products and your Triumph model. INTRODUCTION & BASICSĪs you make adjustments and modifications to your Triumph, there are certain modifications that will change your bike significantly enough to need a tune in order to get the most out of it. Changing your bike’s tuning can also nullify factory warranties. Changing your bike’s stock tune can change its emissions rates, which is illegal in some states (including the state of California). LEGAL DISCLAIMER: It’s your responsibility to check about the legality of certain performance parts and tunes in accordance to where you live. In each section, we’ll describe the fuel system and best practices for tuning your Triumph Motorcycle. 2016-Up Liquid Cooled Triumph Motorcycles (Fuel Injected).2008-2017 Air Cooled Triumph Motorcycles (Fuel Injected).2001-2007 Air Cooled Triumph Motorcycles (Carburetted).Health Insurance Policy - Compare & Save Big! - (InsuranceDekho.Renew Bike Insurance - Save Upto 75%* with Best Insurance Plans - ().Essentially, this allows the owner to backtrack to the stock ECU when it's necessary. This power commander usually come in the form of a piggyback unit that’s designed to work with the factory ECU. Alternatively, you could upgrade the module with an aftermarket performance ECU from PowerTronic or Bosch which can fine-tune set ratios through downloadable power maps in order to offer better fuel efficiency or improve performance. Modern-day motorcycles like the KTM 390 Duke, TVS Apache RR 310 and the Royal Enfield Interceptor 650 have an ECU with a standard map that controls all these aspects. It then cues the hydraulics in the brake calipers to apply or release the brakes, thus preventing the wheels from locking up, offering better control.Īlso Read: Motorcycle Quickshifters: How Do They Work? Under hard braking, the sensors in the wheel send out a signal to the ECU which calculates the wheel rotation speed and acceleration. Electronic rider aids like ABS, cornering ABS, traction control, launch control, electronic suspension damping, wheelie control, engine brake control and various riding modes are all controlled by the ECU.įor instance, an ABS setup comprises of four major components: sensors, valves, the ECU and actuators. While the engine is one aspect that’s controlled by an ECU, it’s also responsible for monitoring and handling a bunch of electronic nannies on bigger, more powerful bikes. The ECU can also adjust the valve lift timing (Variable Valve Timing) in some engines to offer better low-end grunt or improve top-end performance.Īlso Read: What is Ride-By-Wire Throttle? As a result, you get precise fueling for optimal combustion which leads to better throttle response, improved performance and a fuel efficient engine. To elaborate, the ECU uses multiple sensors to calculate a number of variables like air pressure and temperature, throttle position and engine speed to offer the exact amount of air and fuel mixture required for proper combustion inside the cylinder. In the same way our brain detects smell, sight and sound and acts via our legs, hands, fingers and such. In essence, the ECU takes inputs from various sensors, processes them and send out a signal to the concerned electronic component to act upon it. The ECU can be considered the brain of the bike while the engine is the heart. So, without further adieu, here’s how an engine ECU or ECM (Engine Control Module) functions.Īlso Read: Carburettor Vs Fuel Injection: Difference Explained No, it isn’t black magic but simply some electronic trickery that helps your modern day bikes run better. That said, very few actually understand the workings of this magic box. If you’ve been following our tech articles, you must have read the term ‘ECU’ (Electronic Control Unit) on more than a couple of occasions. An ECU uses electronic trickery to help modern fuel injected motorcycles run better.
