hey guys,

ive got an EA MPFI falcon s
i was wondering if it would be advisable to advance my timing
my mate did it on his VL and he said he noticed the difference

is it worth it to advance it? if so wats the best way to go about it?
thanking you in advance
cheers, alex

Timing light, loosen the dizzy clamp bolt to allow you to move it, start car in test mode, once idle settles, turn the dizzy anti-clockwise till the timing jumps up 2 or so degree's, take out of test mode and do up the bolt :)

if you are going to run straight BP ultimate or even (pokes tongue out) Optimax, you can get away with a heap of timing - base timing should be about 10 degrees stock, i think mine is up around 18 or even 20 - it was set on a dyno, and in test mode the car wont idle 'tidily' enough to get a proper reading, i only run BP Ultimate and no pinging :s6:

20 degree's here.. but now i've got other issues to fix.. *grumbles at CFI and possible blown head gasket*

I usually find it best to set the timing without using the light.
Each individual engine will require slightly different timing depending on condition, fuel, modifications, etc.

The best way to do it IMO is to do it 'by ear' - i.e. twist the dizzy with the car at idle until it runs att it's fastest. Then take it out for a drive. If it rattles under load, bring the timing back slightly and try again. Once the rattle is gone, this should be pretty close to the optimum position for your car.

MongrelEB,

Thats how I did mine. Worked wonders.

*contemplates swapping the falcon for a beat up escort*

I adjust my timing much the same way 'mongrelEB' does, though I also use a timing light to see where the timing is.

Rollin -
I've found that Optimax, Mobil 8000, and BP Ulptimate all give identical results, anything less and pinging is evident. Even Caltex Vortex will ping, and it's only 2 points lower.

What's that?..... Did I hear you say TQE power?

so the real question is, is it worth advancing the timing, and spending extra on pulp?

so is there a noticable performance increase?
ive heard pinging is barely noticable so how will i know, and what exactly is happeneing when the engine is pinging and does timign affect it?

also, how do u run ur car in test mode?
