Description: Harris Speed Works Inc. is pleased to introduce to the world the first smart dual stage progressive nitrous controller. The MicroEdge+ controller packs a powerful punch in the features department without draining the bank. With features such as: Dual Stage Progressive 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.


Feature Set of The MicroEdge+:

Dual Stage Progressive Control: Time or RPM based progressive control. Independent solenoid frequency for either stage (40 amp load capacity). RPM or Time Based Linier or Non-Linier (Multi-Point) Progressive Curves. Different progressive curves for up to 4 gears (mix and match between RPM & Time based progressive).

Digital Bottle Contents Indicator: Displays the amount of nitrous left in your nitrous bottle (display in both pounds & percent).

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 Progressive, 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 Progressive Build, Amount of Nitrous left in your Nitrous Bottle (Lbs. and %), 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.
