This is the DIY-EFI SpeedySim Rev2.

A product to allow you to test the inputs and outputs of your ECU.
It was developed to 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 4 headers via the supplied cables to connect to your inputs and outputs.

SpeedySim has an onboard Arduino compatible Nano which runs the Speeduino version of the 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 RPM potentiometer.
