• I hope you find this site a good resource of information. I am constantly updating the site, especially the Support page, so please check back every so often.
• The files on this site (Downloads Page) are obviously free to all in the true MegaSquirt spirit, but bare in mind they are to be used at your own risk. If you are in any doubt simply e-mail me.
• The base configuration files are also there for you to try at your own risk, these are from people who have bought MegaSquirt's from me and have kindly sent me their finished files for others to benefit from or they are base files I have made to get people started.

# 16x16 fuel tables (MS2-Extra Only) (Manifold Absolute Pressure x RPM or Throttle Position x RPM)
# 12x12 fuel tables (MS1-Extra and MS2-Extra) (Manifold Absolute Pressure x RPM or Throttle Position x RPM for ITB's, etc)
# 12x12 spark tables (Manifold Absolute Pressure x RPM or Throttle Position x RPM for ITB's, etc.)
# Rev limiter (Retards ignition then round robin spark cut or fuel cut or both)
# Overboost protection (Round robin spark cut or fuel cut or both)
# 12x12 Mappable Air:Fuel Ratio targets (MS2-Extra Only) (For use with a wideband lambda Sensor)
# 8x8 Mappable Air:Fuel Ratio targets (MS1-Extra) (For use with a wideband lambda Sensor)
# WideBand or Narrow Band Lambda Sensor compatability
# Coolant temperature related ignition timing advance (helps speed up idle during warmup period)
# Inlet Air temperature related ignition timing retard (helps prevent detonation due to excess heat soak)
# Manifold Absolute Pressure rate of change or Throttle Position Sensor rate of change acceleration enrichment
# Overrun fuel cut (Reduces fuel usage by cutting fuel during overrun)
# Hybrid Alpha-N (For very lumpy cams, ITB's, massive throttle bodies, running boost.)
# Staged Injection (Ideal for 2 different sized injectors e.g. Rotary's)
# Built in Air Density Correction (Using Manifold Air Temperature Sensor)
# PWM Idle Control valves (MS1-Extra and MS2-Extra - For use with 2 or 3 wired variable valves)
# Stepper Motor Idle Control Valves (MS2-Extra Only Note: MS1-Extra can NOT control STEPPER MOTORS!)
# Fuel and Ignition or Fuel Only or Ignition Only (Can be used for a fuel only controller or ignition only or both)

MS1-Extra can also control the following cam/crank signals directly:

MS2-Extra can also control the following cam/crank signals directly:

Up to 4 of the following features can be added, please see the MS1 or MS2 Products page for more on these or see the comparison chart HERE:

# Nitrous control
# Dual wheel decoder/2nd trigger input
# 400KPa (38PSI) MAP sensor
# Switchable map tables for Fuel or Spark or both
# Boost control (Closed loop is Experimental code)
# Water injection control (MS1-Extra Only)
# Dual EGO sensor support
# Shift / Warning Lights
# Launch Control / Flat shift
# Real-time Barometric Correction
# up to 4 programmable Outputs
# Knock sensor input
# Tacho Output for coil pack use (Standard fit to most of my ECU's, see descriptions)
# Mass Air Flow Meter for fueling calculations rather than MAP or a TPS
