:o000
Depends on what you have in the multiplier table and how everything else is setup.
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.Quote:

So that table not only adds spark but also switches to the eq ratio (alcohol) table?Quote:

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.Quote:

HP Tuner peeps, I take it you did not find a correlating multiple table? There still should be some connection between these in the code to determine the scaling.
I'm running a little high on IDC and would love to lean a little with higher E mix, but without confirming the scaling I'm hesitant.
