This software was developed on the dyno specifically for our 2001-2005 E46M3 that competes in SCCA's National T2 Class. Like our standard M3's Shark Injector software for the M3 - it removes the top speed limiter , increases horsepower (optimizes ignition timing, vanos and fuel maps for 93 octane gasoline) and is designed for a cat back exhaust, BUT this specific T2 software also increases the rev limiter to 8600rpm and turns off a few of the cars OBD2 systems that could cause the check engine light to illuminate (T2 rules say that the CE light must not be on after the race ! ) This software is recommended for race use only (mainly because of the high rpm limit) but will work on any M3.
