The Spec E9x series tune for the N52B30 engine. The Spec E9X Tune by Epic Motorsports includes specific software calibration. The Spec e9x software optimizes engine output when running the required 330i intake, spec headers and 3" exhaust mods. The ignition, camshaft, and VANOS values have been optimized, as well as fuel maps, to match the more aggressive timing and remove or raise the artificial torque limiters. Throttle response is improved, and there is more torque available in the midrange. This tune produces more horsepower and torque and a smoother-running engine while keeping cars in the class on a level playing field. Significant horsepower & torque increase, especially in the midrange. New cooling maps for lower coolant temps. Electronic Throttle Control System (EML) adjusted so throttle blip now works while in threshold braking. All engine protection is still in place with adjusted values for on-track performance. Removed DME faults and warning lights that are unnecessary on a race car. The Spec E9x Calibration will work on MSV80 & we can convert MSV80.1 DMEs to MSV80. It will not work on MSV70. For information on how to convert the 325 & 330 to run on MSV80 click here. Optional: Remove the BMW EWS (security system) from your Spec E9x MSV80 DME to allow use of a matching MSV80 chipped key & CAS without a matching DME. Notice of Emissions Non-Compliance.
