If there is anyone that is running a E30 Tune, I was curious as to how your gas mileage compares to that of the 93 Tune? Assuming that you had a 93 Tune prior to changing to the E30 Tune.
Hey @metroplex , I saw (over on the HPT forum maybe?) that you enabled your master switch for Flex Fuel Enablement. I saw that in VCM Suite as well, but I also noticed all the tables for Flex Fuel were all zeroed out. So nothing is populated over on that side. What did you use to populate those tables? Or did you just leave them all zeroes and the PCM calculates them during operation or something?I've noticed a drop of 2-3 mpg with E30+. I'm on about E60 right now and saw a solid 3 mpg hit with all the WOT testing. I was averaging 20 mpg with 93 octane and now I'm at about 17-18 mpg. Keep in mind this is with a lot of WOT testing.
My car tells me I'm getting 25mpg or so combined. On 93 octane I was doing 2-3mpg better. I'm not sure how much of that is my driving or the tune.If there is anyone that is running a E30 Tune, I was curious as to how your gas mileage compares to that of the 93 Tune?

What about your ECM 21320, for instance? Is that all zeroes?If you're talking about tables like PE Fueling or otherwise (labeled as FFV) I just copied over the non-FFV values. I don't think I made any changes to the Flex Fuel tab other than to enable it and maybe populate the alcohol content. I used my Explorer flex fuel factory settings as a guide. With the 10 gallons of E85 in my tank, the LTFT was close to 0% so that tells me something was adjusted. Normally with E30-E40 w/o Flex Fuel logic enabled, the stoich needs to be richer OR the LTFT will show a highly positive percentage to indicate fuel is being added. At 90F ambient the charge temps were toasty but spark was not being really pulled. It's insane.
