Finished up tuning on pump 93 getting ready to move to flex/e85. Have some basic questions. I understand the 0411 isn't amazing at it but it's what I got.
Let's say my Error on 93/E10 is roughly 1-2% at WOT and I run e85. When the pcm calculates the new target will it still be within the 1-2% error range? Probably not right?
As far as spark tuning goes when does the pcm start to use the ethanol table? A specific content? Or it kind of interpolates the spark in based on content? I'm assuming this is also hard coded?
Thanks
