INSTALLATION INSTRUCTIONS
1. Disconnect the ground terminal from the battery which is located in the trunk.
2. Locate and remove the Engine Control Unit (also known as the DME) from the vehicle by unscrewing the
black cover (A) to reveal the DME itself. Disconnect the main harness connector by prying out the metal clip
and gently lift the connector off the DME. (NOTE: Handle the harness with care, as on older cars, the wiring
becomes hard and brittle and is a weak point). Then slide the DME outwards by hand.
3. Ship ECU to VF-Engineering for re-programming TOGETHER with the “ECU Return Form” found herein.
Make sure ECU is securely packed when shipping. VF is not responsible for damage during shipping. ECU
programming will be delayed if the ECU is returned without the ECU return form. Once the flash has been
completed, ECU will be returned promptly if you have provided return shipping payment info.
4. Remove he coolant expansion tank cap and the raise car. Remove the under tray and drain engine coolant
from drain plug at bottom corner of main radiator.
