Some forms of flashing are frowned upon, and rightly so. However, ECU flashing has become a staple part of sportsbike lifestyle in recent years, particularly as superstock racing now permits ECU fettling, and rightly so. Is the good old fashioned fuelling module redundant"
Based on these results, yes. At just over £200 for an exclusive map (plus dyno time), it?s not only more effective but cheaper than a fuelling module too. That said, Power Commanders and the like are still used as a piggyback for realtime dyno work and fine tuning fuelling. Let?s not forget that we?re dealing with a stock ECU, exactly how the bike left the factory. It?s what?s inside ? and its adjustability with the relevant software ? that counts. As well as superbike exotica, with infinite levels of racing electronics, happy shoppers such as the SV650 and ER-6 have mind-blowing levels of fine tuning and Gucci features hidden inside a stock ECU. Some time ago, we raided JHS Racing and brought along the 44Rewards Yamaha R1M for an ECU remap. With the help of Will Holland (the most technically astute teenager in the world) and Rich from Woolich Racing, we spent the day on the dyno extracting the most out of the R1M.
As you?ll soon fathom, flashing and remapping ECUs certainly isn?t all about peak power gains and eleventeen billion bhp dyno readings. All bikes have their own distinctive foibles, the R1M?s being a snatchy throttle and general poor ride-by-wire execution.
The results speak for themselv...
