Timing problem

You won't necessarily 'see' the timing move (looking at a timing light) while you rev the engine sitting there in neutral.

The computer looks at RPM, vehicle speed, load, throttle postion, engine temp., intake air temp, etc, etc,etc. Then it decides where to set the timing.

Just jump the terminals, set the timing to 10*-15*, remove the jumper, and drive it. I bet the timing is working correctly, as I have not seen one thread on several supra forums about timing not advancing properly.
(nor in the shop either).
