Spec E9X - Epic Performance Software (N52)
*Note: we are in the final stages of tuning the spec e9x tune* Will be available in early August.
The Spec E9x series tune for the N52B30 engine. The Spec E9X Tune by Epic Motorsports includes specific software calibration to remove the faults and warning lights that are unnecessary on a race car. It also makes a great power increase while keeping cars in the class on a level playing field. Please note that this is for MSV80 only. For information on how to convert the 325 & 330 to run on MSV80 click here.
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. This tune produces more horsepower and torque and a smoother-running engine. Throttle response is also improved, and there is more torque available in the mid-RPM as well.
Note you have the option to remove the BMW EWS (security system) from your Spec E9x Tune to allow running your original a chipped key and CAS without a matching DME. After you place your order we will send you a label to mail in your DME for calibration.
