Alcohol PE timing adder DID add the full 6* of timing, as shown in the logged full Timing Advance, and definitely felt and dyno'd like it should have (when tanked with E80, as I expected to according to my Multi table). But, the add appears to be either zero or full amount from the PE table, and the Multiplier didn't appear to have been used (no effect) for partial percentages of ethanol. All or nothing - so, I believe the lesson here is to be careful when running a blended tank, using a FF sensor, and aggressive E85 timing. I know this to be true for the PE adder table but have yet to see if the Multiplier DOES affect the values in the FF Spark Table.

The PE timing add should be 4* (6* from the PE table multiplied by 0.667 from the Multiplier table) - but it's not.
