I tried to do my timing the other day as the guy from Gizzmo was shocked to see it full advanced, but the timing light hardly pick up anything, is there something i need to turn off so that the idle timing isn't retarded?

Also once I get it ready where should I set it ?
I'm assuming just before it starts knocking.

On the 1G there is a connector in the enginebay on the firewall, its brown and taped to the loom. Connect a jumper wire between the connector and the chassis. This puts the ECU in timing adjust mode. If you do it with the engine running you should notice the idle change as soon as its connected. I'd set it somewhere between 5 and 9 degs, depending on the fuel and you how good your compression is. The ECU will retard the timing if you go to far (knock sensor) but it retards more than you need to so the optimum is where the computer isn't making any adjustment to your setting. Usually I'd stick with 7deg for pump gas (98 only and 5 or 6 deg when using 96) When you finished adjusting the timing, remove the jumper and your done.

I don't think the timing on 2G models needs (or can) to be adjusted, they have a crank angle sensor so ECU can work out the timing from the cam position vs crank angle.

Gen2 has an adjustable cam angle sensor that the americans use to alter timing on there eclipse's. Not sure about the crank sensor but I dont think its adjustable. Both of which probably should be played with anyway.

Otherwise ajustable cam gears.

Can you show us a picture of the connector you mentioned?
