ESS E-tronic provides safe, simple to add power to the already potent F8X M series. Unlike other products on the market E-tronic is a sophisticated multi channel controller that has RPM and MAF intergration.

All of this without the need to splice into any factory wiring. OEM grade hardware is used to provide high quality, safe, reliable power with excellent driveablility. 3 pre-set calibration maps provide for a very simple installation without the need for setup or adjustments once installed. The included multi stage maps provide everything from linear power delivery for improved traction under boost to max HP / TQ with the use of higher octane fuel. E-Tronic can be disabled or removed from the vehicle at anytime allowing customers to keep their factory warranty.
