Spark timing
Spark timing I've been using my scanmaster on my 01 and I know the car is using the low octane table, I'm only seeing 15% of timing. The car actually feels decent considering such low timing. The only mods are Lid, Headers, and FRA. I know you can copy the normal table over to the low octane table and take care of it, but why would it continually do this. Even when I reset the PCM it still only gets 15% of timing.

Check ASPARK which will tell you if your adaptive spark is messing, but that should get reset when you reset PCM.
You might need to log spark modifiers like ECT/IAT etc, they will pull timing if too hot etc.
Also if you have some certain DTC's or are running a stock OS in speed density mode you will also run from low octane table.

Well it finally showed a DTC today P0332 which is knock sensor. Now I found 3.9 degrees of knock. I'm gonna replace the MAF and knock sensors and see if that doesn't get it straightened out.
