Is the ECU pre-programmed?
All of our ECUs are shipped pre-programmed and bench tested.
If you have purchased an ignition or EFI kit, the ECU is tested along with the loom and sensors, essentially as it would be installed in your car.
Crank pulleys and crank trigger sensors are mounted on a special test rig which spins the crank pulley to generate the trigger signal. Injectors are connected and tested and coils are even connected to spark plugs.
The entire system is test run to ensure that it will work when installed on your engine
