Timing Question

[sidewazegtst]

Hi guys.

I just wanted to know which way is advance and which is retard on the cam angle sensor (round piece on timing cover)?

As well I heard that the Timing Position Sensor has to be dissconected as well is this true? If so where is it exactly? A pic or diagram would be sweet.

Currently, for some stupid reason, my timing is advanced by approximately 5 degrees and it appears my CAS is turned more towards the driver's side of the car. All I plan on doing is attempting to get it back to the stock reading of 20 degrees. If by chance I retard it by a degree well, it's better then being advanced. I'm also hoping doing this will improved throttle response as it's a little sluggish in the low rpm's.

Thanks everyone I appreciate this.

when standing in front of the car looking at the engine

Advance = Anticlockwise

Retard = Clockwise

TPS = Throttle Position Sensor

Advanced timing gives more response / smoother accel

too much and it will ping

Hey man thanks for the info on which way is which. That confirms what I heard.

Now I know TPS usually stands for Throttle Position Sensor however my buddy was talking about some timing position sensor and that it has to be dissconected. Is he right or no? I thought I just disconnect the battery, adjust the cam angle sensor, reset the ecu and that's that. I just don't want to fuzz anything up doing this.

As I said I just want to put it back to roughly stock, nothing more.

I am curious though as to what you said regarding advancing timing. I've always read and been told you retard the timing on a turbo charged motor, not advance it, in order to get better response and prevent detination? Also my engine seems sluggish right now in the low rpm's when it should just go if I pin the throttle and all I can attribute that to is the timing being advanced. My motor is currently bone stock (even the stock air box :lol: ) so again there was no real logical reason for the advance.

Tell your mate he's a wanker.

As with any petrol ignition engine, you can't adjust / set the timing while the engine is off. It needs to be running - at normal operating temp - and you check the timing with a timing light while you make the adjustments.

If you retard the timing, part of the burn, and therefore the power production, happens too late, and can even happen after TDC - as the piston is already on its way down the bore. Doesn't make for good power production. Advance it and you ensure the maximum burn rate, and therefore maximum power production, occurs just before TDC. Advance it too far and you induce pre-ignition (pinging / detonation)

I'm using an inductive timing light that is clamped onto a spark plug wire between the coil and cylinder #1.

With this setup, is there something that I have to disconnect like this guy is saying?
