• Fit board to adaptor
The NIStune board simply plugs onto the adaptor. Be careful to check that all pins line up correctly as the
connector is not polarised. Installing the board offset by 1 pin will cause the ECU to run in “limp” mode.
It is recommended to use hot-melt glue (or similar) against the edges of the 20+20 connector to ensure it stays
attached to the board. This will prevent movement if the ECU suffers vibration.
