V8 Engine Setups see HERE.
Up to 4 of the following
features can be added to the MS1, MS2 or MS3
(Please note that the MS3 can have an MS3X card adding which gives all sorts of inputs and outputs, etc, see HERE)
# Nitrous control
# 400KPa (38PSI) MAP sensor
# Switchable map tables for Fuel or
Spark or both
# Boost control
(Closed loop is Experimental code)
# PWM for Water injection control
(MS1-Extra Only)
# Dual O2 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
TPS)

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
Every
ECU package sold includes:
# A fully labeled /
colour coded wiring harness
(approx. 1 meter)
# An RS232 communication cable
# Tuning software, drawings and various manuals

Welcome
to ExtraEFI.co.uk.
I have been building MegaSquirt ECU's since 2003 and I'm one of the team who wrote the MS-Extra Code.
So you can rest assured this is THE place to purchase your MS ECU, in the UK and EU, with the knowledge that you will be getting what you need, rather than what someone wants to sell you.
No other MegaSquirt sales website comes close to this one for information, knowledge and backup of MS ECUs! Everything you need to know is on this site, that includes video help files! If you still have any questions then I can answer them due to my experience with the actual firmware the ECU's run and with the years of experience I have building and testing them!
ExtraEFI was setup in 2005 by myself with a simple aim; to
supply fully assembled, tested and warranted MegaSquirt ECU's to a very high standard.
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 MS-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:
#Fuel table
(12x12 on MS1 - 16x16 on MS2 and MS3) (Manifold
Absolute Pressure x RPM or Throttle Position x RPM)
# Spark table ( 12x12 on MS1 and MS2 - 16x16 on MS3) (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)
# Mappable Air:Fuel Ratio targets
(8x8 on MS1 - 12x12 on MS2 and MS3) (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 (For use with 2 or 3 wired variable valves)
# Stepper Motor Idle Control Valves (MS2 and MS3
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) |
