Are you making use of the full potential of your sequential gearbox?
Unless you are “flat-shifting”, you are not realising the full potential of your gearbox and 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.
Many aftermarket engine management systems incorporate a basic flatshift function, but this will usually only have provision for a single, fixed, cut duration. More expensive management systems may allow gear dependent shift cuts, but this is still a significant compromise. The Geartronics Flatshift ECU has the added sophistication of using closed-loop control of the engine cut, 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 engine power before the gear has been fully engaged, leading to significantly reduced dog wear.
The flatshift ECU can be used either standalone or in conjunction with your engine ECU’s internal cut strategy (providing that it’s capable of cutting the engine for as long as the input remains active). It even works with engines running on carburettors!
The ECU can be triggered by several methods; including load cells, microswitches or potentiometers connected to the gearbox shift mechanism. This unit is particularly suited to Sadev and Drenth gearboxes that incorporate a built-in trigger switch.
