The ARC2 works along with your existing engine management computer to extract peak performance from your engine.
Installation of Split Second products
This Elise has taken the Split Second approach. Through feedback from the ARM1 and air/fuel control from the ARC2.1, the engine’s air/fuel ratio can now be adjusted from the driver’s seat. The ARC2.1 can be mounted in a convenient hidden location and provides a remote control knob suited for tight spaces. This permanent solution will not compromise driveability or fuel economy. Another feature of the ARC2.1 is its altitude compensation. This feature automatically maintains the proper air/fuel ratio as you travel over varying elevations.
