    You have your MAF disabled, so I guess you are trying to run SD? Your DTC's--P0101,102,103 should be MIL on first error so it will go directly to SD. Your Low Octane table should be about 4 degrees less than the high table. You may have to revise your VE table after changing the DTC's. I didn't see any knock. I have my knock tables at 500/100 and no problems.
