Hi Guys I've hit a brick wall with this, my first problem was that asa i got to say around 5000rpm my power curve flatlined which then i found the problem to be in my blending tables (event based) to be exact, once i sorted that out it was better but not as good as the other 2018's that I've tuned.
I also have when logging INFERRED AFR SOURCE showing (fault exist) ??
Under Spark, try copying your emissions reduction spark tables from gas to the FFV (alcohol) tables. Also finish your blending under flex fuel ignition timing and event based flex fuel values. That should get you started. Attach a log after you do that.
finaly getting back to this & i geuss if you hit a brick wall the best thing to do is start again from scratch & understsand what these changers effect.. happy days again.
