However only the MK2 Sharktuner suports the Alpha-N MAF-less option. They can also be uploaded to the laptop for archiving.Īll the facilities previously available with the New Sharktuner Mk1 with PEMs are also available in the Mk 2 SharkTuner. Both LH and EZk parameters can be datalooged simulataneously for system evaluation, all LH and EZK System monitors, maps and parameter screens are readily available on the screen.Īny edits to the maps or parameters are instantly written to the PEMs. Special Sharktuner compatable software files are loaded into the PEMs, and then tuning can start. A laptop is used to control the SharkTuner and nhence the ECUs. The SharkTuner is powered by the diagnostic connector fitted to all 928s. The standard EPROMs are unplugged from the LH and EZK ECUs, and then closed again, and refitted into the car. The SharkTuner allows the operator to make changes in real time to the software of the LH ECU by modifying a special EPROM binary files provided with the SharkTuner. A custom Windows interface program runs on the laptop, and a slave microcontroller in the SharkTuner acts as the interface between the laptop and the LH ECU. The SharkTuner is a hardware interface between the LH ECU (fuel injection computer) or the EZK ECU (igntion computer) and a laptop computer. This is particularly important if the engine has been modified in any way e.g. The current version is for Porsche 928 (MY 1987 onwards) allows the optimisation of the fuel and ignition maps to ensure optimum performance from the engine. This is used with the Programmable EPROM Modules as described elsewhere on the website. The latest addition to the SharkTuner family is the Mark 2 version.
