The BOSCH ecu is being reverse engineered and will go into open source once all the tables are decrypted, after that it will be easy to basically "copy paste" the needed tables of the 35is ECU (since its using exactly the same as the 35i) and voila, 340hp and overboost function.
What's weird is that for the US market BMW used different brakes for the 35i and 35is, in Europe they use the same size, whats different only is that the exhaust terminal has less restrictors for sound increase, different aesthetics in front and rear bumper, some is and M graphics in dash and interior and silver mirror caps. So basically a fully loaded 35i (like mine which has all the extras) is a 35is without the aesthetics and the overboost function. So basically the OP makes some sense, but for the Euro market.
