Customer Feedback


MS1 can control many setups,
including those below:

# Dodge Neon crank decoder
# Fuel Injection Control Only
#Distributor Based (e.g. TVR - RV8, Pinto, etc)
#Ford EDIS 4, 6 or 8 Setups
(e.g. Cosworth, early Zetec's, etc)
#Ford TFI setups
#Rotory Engines
(Mazda RX7)
# VW / GM / BMW / Bosch 60-2 crank signal
#4G63 DSM (Eclipse/Talon/Lazer
)#Toyota VAST
#GM HEI
#4 Cylinder Wasted Spark
(e.g. Ford Zetec, VW, BMW, etc)
#4 Cylinder COP
#5 Cylinder COP (e.g. Audi)
#6 Cylinder Wasted Spark
(e.g. Ford, VW, BMW, etc)
#8 Cylinder Wasted Spark
(e.g. RV8, Lexus, etc)
#10 Cylinder Wasted Spark
#12 Cylinder Wasted Spark
(e.g. Jaguar, BMW, etc)
# Rover / TVR V8 3.5L - 5.5L
(GEM's will need a 36-1 crank wheel adding)
# LS1 Trigger
#Neon/420A

Up to 4 of the following features can be added to either the MS1 or MS2
Please see the ECU Price page for more on these or see the
MS1 / MS2 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)

 

Welcome to ExtraEFI.co.uk.
I have been building MegaSquirt ECU's since 2003.
I setup ExtraEFI.co.uk in 2005 which is dedicated to sales of fully assembled, tested and warranted MegaSquirt ECU's.
All my ECUs run the latest version of the MS Extra code.

(Well they would do, as
I'm one of the authors of the MS1-Extra code and author of the MS1-Extra and MS2-Extra manuals. I'm also an administrator of the MSExtra forum.)

MegaSquirt is a standalone DIY mappable Engine Management System that can control the fuel and spark or fuel only or spark only on virtually any liquid fueled spark-ignition engine, naturally aspirated or boosted.
Still confused about MegaSquirt? See HERE

A MegaSquirt ECU can give you mappable fuel and or mappable ignition using:
i)A distributor setup with a simple hall sensor/points in the distributor or a cam/crank signal.
ii) A coil pack setup using a variety of cam/crank signals.
iii) A Coil On Plug setup using a variety of cam/crank signals.

All of the ECU's I sell have the MS-Extra code loaded into them, this has these features as standard:

# 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)

See the ECU Page
• See my Frequently Asked Questions section.
• Take a look at the new support page
• Have a look at the Official MS-Extra Manuals I have been compiling / writing MS1-Extra -- MS2-Extra

As one of the authors of the MS-Extra code and one of the administrators on the main MS-EXTRA forum you can rest assured you are in safe hands from someone who has a lot of experience and knowledge of the MegaSquirt products. For more info have a read of the ExtraEFI company profile
