That said, not having appropriate custom ECU mapping for your motorcycle's specific intake/exhaust modifications can SIGNIFICANTLY shorten the life of some expensive internal engine components, such as the pistons and valves. Q: Do I “need” to flash my ECU if I modify my intake and/or exhaust system?Ī: No, this is America and you can do whatever you want! USUALLY, flashing your ECU isn’t “necessary” in the sense that NOT doing so will somehow cause immediate and catastrophic damage to your engine (in most cases). To better understand the performance improvements that will be made to your specific motorcycle with our ECU flash, check out the example dyno graph(s) listed in the Mail-In ECU Flashing Service product description for your specific bike. In other words, this means that your bike will simply run smoother, stronger and cooler than it ever has before! With our custom ECU mapping, built SPECIFICALLY on our dyno for your motorcycle's EXACT aftermarket intake/exhaust combination, your engine's peak performance, throttle response (and on/off throttle transition smoothness), and longevity will be improved. With our ECU flash, all of those restrictions are removed.įurthermore, installing aftermarket intake and/or exhaust components to improve airflow through the engine are incredibly popular modifications that many owners choose to make to their motorcycles, but without appropriate custom ECU mapping to match the improved airflow provided by those parts, the bike simply won't ever run as well as it should. In most cases, ALL of those restrictions are present to varying degrees in Euro 4 and Euro 5 emissions complaint motorcycles (ESPECIALLY for US production models). Whether those restrictions come in the form of electronic throttle restrictions, ignition timing restrictions, and/or lean fuel mapping for emissions compliance is specific to each motorcycle's year and model. NOTE: With all aftermarket exhaust systems, you must unplug your O2 sensor and plug/block off your AIS for proper functionality.Q: What will having 2WDW flash my motorcycle's ECU actually do for me?Ī: All modern motorcycles come with some form of restriction(s) built into the stock ECU mapping in one form or another for emissions compliance.
