90-93 Instructions      94-95 Instructions

• 16x16 fuel tables
• 12x 12 ignition tables
• Linear interpolation between the cells for fine resolution
• Programmable Rev Limiter
• Multiple Acceleration enrichment strategies
• Overboost Protection
• Closed loop Air/Fuel Ratio mapping when using optional wideband o2 system
• Closed loop idle control
  
• Coolant temp timing advance
• Inlet temp timing retard
• MAPdot accel/decel enrichment
• Overrun fuel cut
• Water injection maps
• Nitrous injection control
• Staged or additional injectors
• Sequential injection with individual trim
• Air Conditioner Control
• EGT inputs
• Shift light
• Onboard knock signal conditioner
  
• 4 bar MAP Sensor (internal) good for up to 44 psi of boost
• Wideband O2 Input.  We recommend the Innovate Motorsports LC-1 or LM-1
• Extra Features added to the hardware:
• Launch Control -  Capable of using the stock clutch switch, alternately you can wire in a push-button if you prefer
• Knock Sensor Input with adjustable sensitivity
• Headphone output for knock sensor - listen for knock while you tune!
• Closed Loop Idle Speed control
• AC Control (yes your ECU controlled A/C will continue to function)
• 100% Plug-n-Play option leaving the stock AFM in place, or optionally you can remove the factory AFM/Airbox for increased throttle response and power. All that's needed to remove the factory AFM is a GM Style IAT Sensor & bung from the above drop down menu, a short piece of aluminum pipe and a cone filter.
• 12x12 Air Fuel Ratio Target Tables for use with wide band O2 sensor for precise tuning and table trim.
• Built-in support for a wide array of ignition triggers
• Built-in 2-step rev limiter with flat shift

• Closed loop boost control
• Table switching input. Change fuel and spark maps on the fly for different fuels, maximum power, maximum economy, nitrous activation, etc
• Input for flex fuel sensor
• Onboard peak and hold drivers support both high and low impedance injectors - No external ballast resistor is needed.
• CANBus connector allows interconnection of other MegaSquirt-compatible devices for additional functions: EGT Input, Automatic Transmission Controller, Additional Sensors.
