Note that all the listed setups would need to
have the ECU configured and built for them specifically,
this is what I do when I build them for you.
MS1-Extra Option Configurations -- MS2-Extra Option Configurations
As can be seen on the following two tables, some functions can NOT be used with others. I recommend a maximum of 4 extra's (not including the use of Spark Outputs), I don't recommend using Boost Control with Water Injection (MS1-Extra) as they can cause interference with each other as both cause a lot of noise inside the ECU.
# NOS - Nitrous control (An output to drive a relay coil that's triggered by a minimum RPM, TPS, etc; It also uses an input that switches to a new timing map or fixed ignition retard. Can be used as an Anti-Lag for turbo applications too. Buffered, flywheel protection circuit +£12 Please Note: This is counted as 2 options, 1 for the input, 1 for the output, so only 2 more can be added) See HERE for more details #NOS - Nitrous control for MS2-Extra Only (up to 2 outputs to drive a dual stage or single stage NOS setup that's triggered by a minimum RPM, TPS, etc; It also uses an input that switches to a new timing map or fixed ignition retard. 2 x Buffered, flywheel protection circuit +£15 for 2 outputs or +£12 for 1 output Please Note: This is counted as 2 or 3 options, 1 for the input, 1 or 2 for the outputs) See HERE for more details.
# Boost control (Target values for boost levels depending on TPS and RPM, controlling the turbo's waste gate high powered FET driver +£10 †) See HERE for more details # 38PSI - 400KPa Manifold Pressure Sensor (The standard MAP sensor is capable of 21PSI of boost, in some rare cases this may not be enough, so a 38PSI (400KPa) sensor can be fitted. +£50) See HERE for more details # Water injection control for MS1-Extra Only (Pulsed water injection output to give a proportional water ratio using a fast acting valve and a water pump relay output high powered FET driver for the valve and a buffered, flywheel protection circuit for the control relay +£15 For water pump relay control ONLY buffered, flywheel protection circuit +£5) See HERE for more details # Dual EGO sensor support (Filter components for a 2nd separate Lambda sensor, 1 for each bank of a V6 or V8 +£5) # Shift / Warning Light (I can add a single output that can be switched by several sources e.g. Air temp, RPM, coolant buffered, current limited circuit ready to directly connect to an LED +£5 Includes a red LED please remind me though, as I tend to forget to include it from time to time :o( See HERE for more details # Launch Control / Flat shift (Limit RPM during takeoff / shifting to get a better 1/4 mile time Buffered and protected circuit +£8) See HERE for more details # Real-time (Constant) Barometric Correction (Really only suitable for hill climbers or mountain dwellers includes filtering circuit and a second MAP sensor fitted internal to detect atmospheric pressure +£25) # Cooling Fan programmable output (An output that controls a relay for your cooling fan. This has a programmable ON temperature and a programmable OFF temperature built in flywheel protection, buffered circuit +£5) See HERE for more details. # Up to 4 programmable Outputs (A driver to control a relay built in flywheel protection, buffered circuit +£5 each) See HERE for more details # Knock sensor input (Connection wiring only!! This needs a pre-built knock circuit, see HERE for more details. FREE internally wired only!!!) # Tacho Output for coil pack use (To feed various Rev Counters high voltage output transistor circuit +£5 ‡) See HERE for more details # Dual wheel decoder/2nd trigger input (For a second hall sensor input opto protected circuit with hall conditioning +£15 For a second VR sensor input including separate VR conditioning circuit +£35) Up to 4 additional items like, launch, prog outputs, knock, etc can be added. For more info on these functions please contact me. † - This code is experimental although some
people have had some considerable success with the system. |
MS1-Extra Option Configuration
Note: Two functions in the same row can NOT be used together!
e.g. NOS and Water Injection as they are not used in another pad, etc,
but NOS and Tacho could, as tacho can come from JS3.

Not recommended to use these together.
Note: Most outputs can be set for Tacho, ExtraEFI.co.uk uses JS3 if available.
MS2-Extra Option Configuration
Note: Any function in the same row (A B C D E or F) can NOT be used together!
(e.g. if your using a
Stepper motor for idle you can not use NOS control as its not used in another
pad, etc,
but Stepper motor and Tacho could as Tacho can come from JS11, or others.)
