What should I be expecting with ECM advance at idle?

I'm showing like 27, I think. I advance the dial on my light to about 17 ti find my 10 degree mark. Is this correct?
I've been going through TFI modules (on my third). Seems the truck has a different personality every time.

The ECU adds 16 degrees of timing.

Thanks, It is dropping rpms too low and stalling at times. After warm start, usually just once, sometimes with gear selection change.

I just changed out the TFI module(again) 6-8 months on the prior, several years of very poor performance on the one previous to that. I remote mounted this one. It acts now like the power band is different again. Getting tired of this shit.

Interesting that it's hit or miss with parts sometimes, my Motorcraft distributor and Motorcraft TFI module have been on my BKO since 2004 and still going strong.....IDK......

Great info here! I took my newly purchased 89 Bronco to the smog shop (it's like going to do your taxes when you know you are gonna owe) and it failed. Took it home and found a bad vapor canister and needed to adjust the timing. It was at 22 deg. BTC. I unplug the spout connector and set it at 10 degrees BTC and when I plug it back in it jumps back up to about 22 degrees again. This was one issue that caused it to fail the smog test. Is this normal or is something else causing it. Any help would be appreciated.
