well I knew about the ACIS, but what about 'electronic timing advance'? because the celica models up to 96 had manual adjustment*

as ive been tuning mine i havent come across any adjustable timing device apart from the distributor on a stock rev3 3sge

I believe electronic timing advance is just a fancy word for saying the ECU intecepts the signal to the ignition coil, and judging from the air temp reading or MAF reading it will advance or retard timing.
Ive heard of people with the Altezza (also 3SGE) replacing their air temp sensor with a variable resistor (dimmer switch thing) in order to manually adjust timing.

If your valve cover does not say BEAMS, you dont have VVT (variable valve timing) in any shape or form.
