Detonation

Software has been downloaded (didn't know it was free) and the $50 USB cable arrived (making the software not so free).

I'll be diving into the tables this weekend.

UPDATE

Before changing the base timing table or any parameters that could modify the timing, I decided to throw a timing light on it to verify nothing has changed. I couldn't find my newer, adjustable timing light, so I grabbed my trusty chrome Sears Penske old school light.

lol and behold...timing at idle was like 26!

Once I find my other timing light, I'll do a comparative test, but I don't know how I could have had any dial back into it. Of course, I can't be that bright because I can't even find the damn thing and I just used it recently!

That would sure change things, but remember, depending on setup, the Sniper could add advance as soon as it sees vacuum.

How does 26 degrees compare to the table now that you can read it?

The ECU was telling me in real time that the timing was at 26, while the light was observing 16 on the dampener.

I think I'm going to start from scratch and set up everything with the laptop instead of the little LCD. Shouldn't matter, but some things are easier with the software. I need to turn off "idle control" so no other influences are present and then set and verify static timing. During that check, rpms are brought up to verify timing stays at the static number. This verifies the inductive delay setting. If timing increases or decreases (as witnessed with a timing light) with increased rpm during the static test, the inductive delay is adjusted. This ensures the ECU is giving you the timing you think you're getting.

I don't know how it changed, or if I just had the timing light dialed back.
