2Boost is another Subaru mod for SH7055 and SH7058 CPU based ECUs. It supports Subaru Impreza WRX G12 and G22, Subaru Forester turbo S11 and S12, Subaru Legacy turbo B13 and B14 and can be used on non-turbo SH7058 CPU based ECUs (without all turbo settings, of course). It allows one to switch between two different map sets by pressing cruise button. Or, if car has Si-Drvie switch, one can switch between three map sets by selecting different Si-Drive modes.
Latest 2Boost version supports map sets for Target Boost, Initial and Max WGDC, Primary Open Loop, Timing, Intake and Exhaust AVCS and Target Throttle Plate Position map sets.
Attention! There is always a risk that you'll brick your ECU. It is strongly recommended to prepare ECU recovery plan before flashing.
