How do you set timing on eb falcon 3.9 litre?

Answer 1

To set the timing you must earth the ECU otherwise the ECU will be constantly changing the timing as you alter the angle of the distributor. You need to make a flat spade connector with a piece of wire and a alligator clip on the other end. On the drivers side there will be 3 spare plugs near the firewall, find the singular female spade connector and earth it by simply clipping it to the body. Earthing the ECU puts the motor into its base timing self test mode. For 30sec the motor will rev to 3000rpm then will drop back down. Then you have 3min to change the timing before the ECU kicks back in.
