Afternoon everyone. So, im trying to get a 15 hellcat on the flex patch. Applied patch, made ignition table changes, sensorless FFV switched to on and everything else that I can see to be modified.. which im sure im obviously missing something. So in the logger, i cannot see ethanol %, ignition advance for alcohol or anything that im used to seeing in the gm side of things that would indicate that it is in fact accounting for Ethanol in the fuel. What am i missing here?

Got it! Hopefully i can help someone out by saying I didn't have fuel volume learning trigger set correctly.
Did you do this on a stock ecm I'm assuming. I'd like to learn how you went about this. There are numerous tables to setup and is above my head.
I put 400,000 in the fuel volume table so it would always be triggering learn.Originally Posted by spoolboy
yes, stock ecu. My first one so proceed with caution with any of my advice. I enabled sensorless FFV in both tabs, changed ethanol spark tables which are zero when you apply the patch. Also changed the blend factor under spark tables. Im probably still missing some steps since I can see ethanol % now and learn is triggered but i cannot verify that spark is being modified yet.
