What kind of values should I be seeing on my OTC 4000E scanner for the total advance (ADV)?

At idle it says 12, 22 on decel, 34 at cruise on the interstate, and WOT it drops to single digits.

At WOT, the scanner is reading '9' in the ADV field. My base ignition timing is 12' BTDC. Does that mean my total advance at WOT = 21 degrees? Does that sound normal for the stock TII logic module?

What year cal? On my 88 Daytona @ wot & full boost the advance was at 10 (10+12 initial = 22 total), But I also was using a zenor doide that could of caused a slightly higher advance a WOT.

It's '87 TII. I am also using a zener diode; it's adjustable and set just under overboost cutout. I'm at 18 psi right now.

That jives with the readings from my Snap-On my scanner.
