for an ea spack multi point , i would like to advance the timing because i allways use shell optimax which is a 98 octane fuel. Would i be able to move the distributer or would that make the computer play up

any suggestions would be gewd thanx

Move the dizzy around clockwise about 5 - 10 degrees. You should notice a significant performance increase if you're currently sitting on 10deg BTDC.

I mean anti-clockwise

daza_mate

yes thankyou, ive advanced it about 10 degrees and it doesnt ping and a signigicant gain in power was noticed

does anyone know if the computer is 100% compatible with this setup of manuel advncing of the distributer

That is the correct (and only) method of adjusting timing.

It is but, on some it causes idle and cruise mixture problems , because when you advance the timing 10 degrees it also advances the injector timing 10 degrees which can sometimes cause the ecu to have trouble on closed loop (sometimes that is). If you notice that on light throttle it hunts or that the idle isn't smooth than just knock it back a tad. The actual correct way to advance the ignition timing is to change the ECU programming.

Hmmm, that doesn't sound right to me.....
That's the first I've heard ignition timing also adjusting injector timing?
Hunting is also mostly caused by a rich mixture not advanced timing. Typically the only drawback of timing which is advanced to far is detonation.

Care to shed some light on who you heard this from?

What do you mean hunting? I've never heard this term...
