at what percentage alcohol does it switch to the alcohol pe table? or doesn't it work that way?

Depends on what you have in the multiplier table and how everything else is setup.
2010 Vette Stock Bottom LS3 - LS2 APS Twin Turbo Kit, Trick Flow Heads and Custom Cam - 12psi - 714rwhp and 820rwtq / 100hp Nitrous Shot starting at 3000 rpms - 948rwhp and 1044rwtq still on 93
2011 Vette Cam Only Internal Mod in stock LS3 -- YSI @ 18psi - 811rwhp on 93 / 926rwhp on E60 & 1008rwhp with a 50 shot of nitrous all through a 6L80

Check the "[ECM] 12636 - PE/COT Spark Advance Correction Mult vs. Fuel Composition" table. Here is how I have mine set up. Basically nothing happens until 10%+ then it interpolates up to the 20% cell.Originally Posted by davez28

So that table not only adds spark but also switches to the eq ratio (alcohol) table?
Sorry my bad...that table only effects spark. As far as I know the PE should always be interpolated based on alcohol % (0-100%) between the [ECM] 12400 and [ECM] 12403 tables.
If the tables are the same, then nothing will change with E during PE. Are you specifically seeing something off in your logs?

Nope, not at all. I've never ran E through my car (yet). I was just confused as to if that flex fuel spark table was doing more than I thought.
