Shark Injector (programmed for headers no cats) for 1999-2006 BMW M3 [E46] + M-Coupe/Roadster

This Shark InjectorTM software has been specifically designed for cars running the Euro headers but no cats. The software “turns down"" the reading from the rear O2 sensors and modifies the tolerances for the EGT sensor. Using an exhaust without the cats and proper software will surely cause a Check Engine light. Because this part deletes the BMW emissions equipment, a Smog Waiver must be signed and on file at TMS before parts can be shipped. This software works best with Euro or Supersprint headers and the Supersprint front section (p/n 787512). Set with an 8100 rpm rev limit. Choose between 91 or 93 octane minimums.
