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
