Here is a comment from a tuner that I read this morning. I always heard that the low table was to be lower in case of knock. As you can see, there is a different opinion. Which is correct??
"That is not true. As long as the knock tables are still active and aren't zero'd out, the PCM will retard timing when it detects knock. The high/low octane tables are for a scalar that will blend between the high and low octane tables when there is long term repeated knock. Instead of pulling timing whenever knock is seen, it will begin to default to lower timing cells. Plenty of people copy the high to low without issues because they keep their knock sensors active."
Thanks
