On my old 95 LeSabre 3800 V6, it had a low octane timing table and a high 
octane table...  The test would determine which table it used, and if it 
used the low table, it used a recovery function to "migrate" the timing 
towards the high table.  The test ran all the time as well so if the 
conditions were met it would revert to the high table.
