DIY-EFI SpeedySim

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.

This is an original, authentic, and authorized product of DIY-EFI.
