Are you making the most of your sequential gearbox?
Unless you are “flat-shifting”, you are not realising the full potential of your gearbox, and you are probably causing unnecessary wear on the drive dogs. If you don't believe us, have a look at this excellent article by William Hewland of Hewland Engineering.
Unlike all other standalone flatshift systems, the Geartronics ECU operates using closed-loop principles, thereby greatly reducing the possibility of gearbox damage.
Most aftermarket engine management systems incorporate a basic flatshift function, but this will usually only have provision for a fixed cut duration. More expensive management systems may allow gear dependent shift cuts, but this is still a significant compromise. The Geartronics easyshift ECU has the added sophistication of using fully closed-loop control of the engine torque reduction, therefore automatically adjusting the cut duration every time you change gear. This means that every shift is timed to perfection with the minimum interruption of torque to the wheels. There is also no possibility of resuming full engine power before the next gear has been fully engaged, leading to significantly reduced dog wear.
A new addition for 2012 is the ability to drive a throttle blipper to allow clutchless downshifts. Not only that, but the ECU also has a closed-loop 'anti-push' strategy to make downshifts even smoother. We're confident that the Geartronics Easyshift is the only aftermarket system to utilise such technology. The Geartronics Easyshift can be used either standalone or in conjunction with your engine ECU’s internal gear-cut strategy (providing that it’s capable of maintaining the engine torque reduction for as long as the gear cut signal from our ECU remains active). It can even be used with engines running on carburettors by directly interrupting power to the ignition coils, although this is a rather crude method that we would wish to avoid if possible.The ECU can accept all conventional trigger methods, including load cells or microswitches. The ECU is also unique in that it can utilise the barrel position sensor to provide the necessary up or down trigger. By accurately measuring the position of the gearbox selector barrel, we can detect the initial few degrees of movement in order to determine when the driver is pulling or pushing the gear lever. This means that in most cases, it's not necessary to use external triggering devices that can be difficult to setup and unreliable in service.
