WARNING

If your ECU pulses the fuel pump, injectors, fuel regulator, flashes LEDs randomly (or they just stay on when they shouldn’t) or your engine does not start then your ECU may not have your board fitted correctly.

Testing has shown on early Nissan ECUs that this can potentially keep the Mass Airflow Meter heater element on longer than 1 second and blow it like a fuse.

Check:

Poor connection between the NIStune board and ECU due to failure to secure the board correctly using hot glue or similar mechanism

Poor header cable connection to the ECU from NIStune board

Mismatched NIStune board configuration for the ECU image you are attempting to use

How to fix this:

Always firstly try ECU with the factory ROM without the NIStune board to attempt to start the car properly

Ensure your NIStune board has the correct base ROM image loaded for your ECU

Ensure your solder joints are good and header connector is installed correctly

Attempt USB Consult connection to the NIStune board to verify communication
