Mod Description
Sometimes (not often) you might need to remove the ECU, either for sending off to get it remapped or to re-site it elsewhere if you fit a different airbox

Disconnecting The 2 Connections

On the nearest part of the connectors are slides that lock in position to hold them in place. Slide them back out by levering them towards the back of the car with a screwdriver.

As the slide is pushed back it will unlatch and lift the plug off of the ECU. If you do the top one first it gives you better access to the lower one.

Removing The ECU From The Car

The ECU is screwed into the side of the airbox. The 8x Torx20 screws are shown below so just take the screws out and the ECU will be free to be removed from the car.
