When tuning ME7 the goal is to calibrate the various maps to model the hardware and the weather accurately. ME7 calculates how much pressure (boost) is required to achieve the load request which is highly dependent on hardware (the engine, turbo, etc.) and also the weather (cold, dry air is denser than hot, moist air). That torque request is then mapped to a load request. Pedal positions are mapped to a torque request (which is effectively a normalized load request). In ME7, the driver uses the accelerator pedal position to make a torque request. The simplified description of how ME7 works is as follows: Improvements to LDRPID make the algorithm more stableĮverything in ME7 revolves around requested load (or cylinder fill).KFMIRL is derived as the inverse of KFMIOP.KFMIOP has been reworked to derive KFMIOP form user inputs.PLSOL -> RLSOL calculator has been added.ME7Tuner works from XDF files for map definitions.ME7Tuner now works from the binary to load tables.The map definitions are user defined and can handle all versions of ME7 and potentially sub-sets of any ME version.Removed 3D rendering which causes lots of GPU problems on Linux systems.There are significant changes to ME7Tuner v1.0 It is somewhat specific to an ME7 M-box ECU. ME7Tuner is software that provides tools to help calibrate the MAF, primary fueling and torque/load requests.
