SpeedySim

Weight2.5 oz

Dimensions3 × 3 × 1 in

This product allows you to test the inputs and outputs of your ECU.
It was developed with the Speeduino ECU project in mind, so has a 40 pin connector which will allow direct plug and play with the 0.4 series.
For all other Speeduino designs (and many other standalone ECUs) you can use the 3 headers via the supplied cables or DuPont jumpers to connect to your inputs and outputs.

SpeedySim has an on-board Arduino compatible Nano which runs Ardu-Stim software to allow the creation of crank and cam patterns.
The default pattern is 36-1 crank only and this is variable using the TPS/RPM potentiometer.

There are 6 potentiometers in total for input simulation.

  • TPS (Also varies RPM)

  • IAT

  • CLT

  • O2 (0-5v)

  • Spare1

  • Spare2

There are 12 LEDs on board for output testing.


4 for injector channels, 4 for ignition channels and 4 for low side driver channels.

Note: The unit will come fully assembled with the exception of the 40 pin header, so the size is smaller if not using with a 0.4 Speeduino board.
This will be included in the package and soldering to the board will be done by the user.

The barometric sensor, also commonly known as the barometric air pressure sensor (BAP), is a type of engine management sensor commonly found on many vehicles. ...

 

However, the BAP measures the pressure outside of the engine, while the MAP measures the pressure inside of the manifold.

we can pin cell pwm to the MAP to increase or decrease with intake demand. 

O2 Sensor wide band need to allow tune  5:1 to 20:1 air fuel ratio ideally upto 34:1

By mixing in the Egr % to a higher amount we can adjust the burn rate to match lower ratios like 20:1

HC-06 Bluetooth module allows wireless communications to the Arduino. Programmed with correct settings and random pin number. Comes with 4 conductor F/F cable.

Saftey Reed Switch Stanley A Meyer GMS can replace the reed with vaccum switch connection if need be or mercury switch 

Reed switch is a kind of passive electronic switching component with contacts with a simple structure, small size and easy to use. It consists of a sealed glass envelope where there are two ferrous elastic reeds and is filled with inert gas called rhodium.

Now, this reed switch is pre-soldered on a PCB board that comes with basic electronic components to help beginner.

Comes with Power indicator LED and status indicator LED, there is also a comparator and potentiometer to adjust the threshold, although it is not really neccesary for Reed switch. Check out the explaination from Robojax:

Single Channel 5V Relay Breakout Board use with reed switch for safety to cut power of crash

Note: From February 2020 onwards, the module comes with a logic low circuit.

The Relay breakout board is a convenient board to be used with 5V microcontrollers such as SK40C, SK28A, Arduino, SKds40A, SK18B. You can easily use 5V signal to control the relay. Three inputs:

  • VCC = 5V is needed

  • GND = Common Ground, 0V

  • IN = Control signal need to be 5V 0V to activate the Relay (Active Low)

The relay terminals (COM, NO, and NC) are brought out using a 3-way screw terminal. On-board relay is rated at 10A. It can be used in many applications: controlling high voltage, high current loads such as motor, solenoid valves, lamps, and AC load. It also comes with 2 LEDs to indicate the status power (VCC) and the status of the relay.

Make a panel to mount a fuse block, few relays and the Speeduino use the reed switch and relay above

2FIRE-FRONT.png

This replaces the stepper module output to add two ignition outputs and a relay output.

Includes unsoldered header pins to allow for cheap envelope shipping.

NOTE: The mounted output resistors are 47 ohm, a different value may be recommended for your coil/ignition module.

Step pin – Ignition channel 1 – B1
Direction pin – Ignition channel 2 – A1
Enable pin – Relay Driver, 650mA rated – B2

V0.3 Board

Overview

The v0.3 board was the first widely available Speeduino shield and is suitable for many typical 1-4 cylinder injection and ignition applications (Excluding direct injected engines). It uses screw terminals for all connections in order to make test wiring simple and quick for prototyping.

Board Features

The v0.3 boards includes the following features:

  • 4 injector channels

  • 4 Ignition outputs

  • Fully protected input channels for CLT, IAT, TPS and O2

  • Optional VR conditioner mount on crank and cam inputs

  • MAP sensor mount location

  • 4 medium current spare outputs (Eg Fuel pump, thermo fan etc)

  • All I/O through screw terminals on the board

  • Proto area with IO, SPI and power breakouts.

Physical Layout

Proto area

The proto area can be used for adding your own circuits on to Speeduino if required or simply as a convenient access point to various connections. The connections broken out to the proto board are:

  • 5v and 12v

  • Grounds

  • SPI pins (MOSI, MISO, SCK and SS). Alternatively these can be used as generic digital IO (Arduino pins 50-53)

  • 3 generic analog inputs (13-15)

High level wiring guide

 

Hyduino can be configured in many ways depending on the engine, sensors, ignition and fuel hardware being used.

 

For this reason it is impossible to provide 1 single diagram that will cover all scenarios, however the below is provided as a high level guide that can be used as a starting point.

See the Hardware Requirements page for specific requirments and exceptions to the image below.

Ignition Wiring

Overview

Ignition output configuration can be one of the most difficult areas of ECU wiring and one that often causes the most confusion. A large part of this complexity comes from the huge number of different ignition types that are available, with there being significant changes in the hardware used in the late 80s and throughout the 90s compared to newer designs.

Whilst this guide does not cover all ignition styles and hardware, it does cover the most common scenarios. Generally, it is recommended (Where possible) to use newer styles of ignition hardware (Typically 'smart' Coil-on-Plug or Coil-Near-Plug) rather than utilizing separate ignition modules.

Wasted Spark NOT SUITABLE FOR HYDROGEN FUELING ON DEMAND use other configon this page 

Wasted spark is a common means of controlling spark that requires only half the number of ignition outputs as there are cylinders, with 2 cylinder being attached to each output. EG:

  • 4 cylinder engine requires 2 ignition outputs

  • 6 cylinder engine requires 3 ignition outputs

  • 8 cylinder engine requires 4 ignition outputs

Wasted Spark has the advantage of not requiring any cam signal or input as it does not need to know the engine phase. This is possible by firing the ignition outputs once per revolution and pairing that output to 2 cylinders that are both at TDC (With one cylinder on compression stroke and the other on exhaust)

When using wasted spark, it is critical the correct pairs coils and/or spark plugs are joined together.

There are many dual pole, wasted spark coil packs available both with and without built in igniters. Either are suitable for use with Speeduino, but use of coils with built-in igniters is recommended

AVOID DO NOT USE FOR HYDROGEN ON DEMAND as grounds engine we want positive earth

use other config on this page 

Note: The above example uses 'smart' coils with built in igniters. Do NOT attach high current (dumb) coils without adding an igniter

Coil on Plug

As an alternative to a dual pole wasted spark coil, individual coil on plug units can be used in a wasted spark configuration.

Note: The above examples use 'smart' coils with built in igniters. Do NOT attach dumb COPs (2 pins) without adding an igniter

Sequential (COPs)

Sequential ignition control using Coil-on=Plugs coils dramtically simplifies the ignition wiring. With this configuration, each coil (and subsequently each cylinder) connects to a single ignition outpt, wired in the firing order.

Note: The above example uses 'smart' coils with built in igniters. Do NOT attach dumb COPs (2 pins) without adding an igniter

Distributor

If a distributor remains in use, only a single output is required from the ECU. This should be fed into a single channel ignition module (Such as the common Bosch 124) which can then drive the coil.

Analog Sensor Wiring

Analog sensors provide data such as temperatures, throttle position and O2 readings to the ECU. The diagram below shows the typical wiring for these sensors.

Injector wiring

Overview

Speeduino contains 4 injector control circuits and is capable of supporting up to 8 injectors (and cylinders) with these.

Supported Injectors

Speeduino supports High-Z (aka 'high-impedance' or 'saturated') injectors natively. Low-Z injectors are supported with the addition of resistors wired in series with the signal wires. High-Z injectors are typically those with a resistance greater than 8 Ohms.

If "Low-Z" ("peak and hold" or PWM-controlled) injectors that are lower impedance are used, the wiring will require series resistors on each injector to avoid damaging the board with excessive current. The resistor ohms and watt rating can be calculated by Ohm's Law, or use an Internet calculator page such as the Speeduino Injector Resistor Calculator.

Layouts

There are a number of ways that the injectors can be wired depending on your configuration and preference.

1, 2 and 3 injectors

For these configurations, each injector is wired into it's own output from the Speeduino board.

4 injectors

For 4 cylinders/injectors, there are 2 ways that these can be connected to Speeduino:

Method 1 (Semi-sequential)

The standard method is the same as that used for 6 or 8 cylinder setups, where 2 injectors are connected to each injector channel. In this configuration, only 2 injector channels will be used. The injectors paired together must have their Top Dead Centres (TDC) 360 crank degrees apart.

Method 2 (Full sequential)

This method is only available on 4 cylinder / 4 injector applications and allows you to wire 1 injector per channel. The injector channels always fire in numerical order (ie 1, 2, 3, 4) so your injectors should be wired to take your firing order into account. Within Tuner Studio, this option can be enabled by selecting:

Settings -> Engine Constants -> Injector Timing -> Semi-Sequential

5 injectors

5 cylinder setups should be wired to use all 4 injector outputs with 2 injectors sharing output #3. For the typical inline 5 cylinder firing order (1-2-4-5-3), injectors 4 and 3 would be joined together on injector 3 output.

More than 5 injectors

For setups with more than 4 injectors, the number of outputs used will be equal to half the number of injectors.

6 Cylinder

For a V6 with a firing order of (1,4,2,5,3,6) the injectors will be wired in 3 groups of (1,5) and (4,3), and (2,6) as these cylenders are 360 crank degrees apart.

8 Cylinder

Inline with the above, this configuration requires each injector output to be connected to 2 injectors.
The injectors should be grouped in opposing pairs, that is, cylinders whose Top Dead Centres are 360 degrees apart.

Two speeduinos, one for each bank, separate map readings but all other sensors are shared. 

  •  Do you use some sort of can bus conection to sync them or just by sharing the sensors its enough? 

  •  it’s also interfacing with the oem controller which puts rpm on canbus for dash and fuel pump etc.  5v ref sensors simply share signals.
    Temp sensors share signals with bias resistors and conditioning capacitors removed. The bias resistor value is that of the factory controller.
    The key is to make sure the sensors and speedys are grounded the right way.

  • Very dependant on engine layout though. This is effectively two straight six’s on a common crank. So taking separate MAP readings and running them individually is pretty good.

  • the temp sensors only require one bias resistor regardless of how many ecus you have.

    In my case 3 ecus, the bias resistor is in the Mercedes controller so I removed both bias resistors on the speeduinos.

    The other sensors you just splice the signal line and feed it in on the corresponding pin.

  • how to sharee rpm signal ?

  • just splice and share the wires, make sure the grounds are common. No pull-up on speeduinos.

  • Twinspark and no room. The 4 post coils are cheap and compact., same way a lot of big engines run. Just means you have to have tunerstudio open twice. One controller is the master and the other is just a slave for ignition and injection

 What kind of ignition is it? Distributor, or waste spark?

wasted spark. Example no good for HHo H2 opr GTNT  as we need constant + ground 

Each ign signal shared by two cylinders through a vag 4 post coil. So each ign signal is triggering 4 plugs to accommodate the twinspark system.

I have an old M73 in storage, thinking of running the distributors, and only use one ignition output pr distributor.

 you use two ignition output pr ecu? And with 4post coil (16cylinders), you have 4 sparks not used?


  • Ign 1 to cyl 1&6 (4 plugs)
