Description: Harris Speed Works Inc. is pleased to introduce to the world the first smart window switch. The MicroEdge controller packs a powerful punch in the features department without draining the bank. With features such as: Dual Stage Control, A/F Shut Down Switch, and multi-gear lockout, the MicroEdge is a technology leader in the nitrous industry. But those aren’t even all of the features that are included! The MicroEdge was also designed to work on any rpm signal, from individual coils/coil on plug to crank position sensors. RPM signal can also be obtained by using the fuel injector or tach output signal. The MicroEdge can also be upgraded to the MicroEdge+ to turn it into a progressive controller power house!

Feature Set of The MicroEdge:

RPM Window Switch: Only operates the nitrous system within a set “window” of RPM.

TPS Activation Switch: Only operates the nitrous system at (WOT) wide open throttle.

Dual Stage Control: Allows for the use of multiple nitrous kits to be run off of one (1) window switch. IE; multiple stages which can be used with different RPM & TPS values.

A/F Shut Down Switch: Nitrous system(s) will shut down if a lean condition is detected by either a wideband O2 sensor or narrowband O2 sensor. The MicroEdge will also shut down the system if an overly rich A/F is detected (wideband sensor only).

Lean Out Delay: The MicroEdge controller can be programmed to not shut down the nitrous system for a determined amount of time if a lean condition is detected. Great feature for those small lean spikes upon kit activation. This feature can be adjusted up to 10 seconds in .05 second intervals.

Multi-Gear Lock-Out: Can be configured for both stages and can lock-out multiple gears to optimize traction.

Time Delays: Activation of kits can be delayed for up to 10 seconds in .05 second intervals.

Pedal Delay: Delay(s) used to re-gain traction if the system is activated and the gas pedal is let off due to wheel spin and then re-applied. This allows for momentum to be built prior to re-activating the nitrous system(s). Both stages have their own pedal delay which is adjustable up to 10 seconds in .05 second intervals.

Nitrous Solenoid Delay: Delays the nitrous solenoid from being activated for an amount of time after the kit is activated. This helps to cure any lean spike issues that are pre-existing in the system.

Display: Built in LCD display can show RPM, A/F Ratio (mV for narrowband), TPS voltage, Battery Voltage, and Arming Switch Voltage.

File System: Up to three (3) files can be saved within the MicroEdge unit for quick and easy loading between runs.

Upgradeable: Easily upgradeable to the MicroEdge+ for progressive control features. For more info follow this link: MicroEdge+
