Simulate ECU Functions

Don’t have the ECU you need for testing?

Need to quickly create a translator, gateway, or filter?


Creating a simulator, gateway, translator or network filter can be expensive and time-consuming, but our neoECUs can complete most rapid prototyping and gateway tasks for less than half the cost of other solutions. These devices are scripted using Vehicle Spy’s easy-to-learn Function Block scripting feature.

Capabilities include the following:

  • Simulate broadcast messages or network management exchanges
  • Simulate an ECU on your bench or desk
  • Create a gateway/translator to isolate traffic or to modify messages sent to a specific ECU
  • Filter unwanted network traffic in a subsystem or test cell

Most neoVIs also have the same capabilities, and can perform these tasks plus act as a vehicle network adapter simultaneously.

Restbus simulation is also possible using a neoVI and Vehicle Spy’s Simulation View.
