Dont, run e30, max e40-e45
Probably the fuel pump not set for correct rate at that map.why though?
First off, welcome and congratulations! I had a flex fuel tune on my turbo FRS as well. Just fill up whatever amount and the ECU adjusted for it. My Supra is still stock, but from what Iāve gathered here and through talking with some shops, getting as close as you can to 30% is highly critical if youāre running an E30 tune. Most people Iāve seen are either googling the mixture by gallons for a final e30 mix or are using those ethanol content test tubes. I know Twisted Tuning offers a flex fuel kit so Iām hoping they chime in.I just (today) traded my 2016 GT350 in on a Supra. The Shelby had a Lund flex fuel tune so I could run whatever ethanol% I wanted without worrying about the exact percentage. You guys are talking about running e30. How critical is that 30% and how are you determining it?
Thanks. I spent many years on MKIV.com before switching to a series of Mustangs in 2005. Fortunately where I live in central CA they don't seem to change the ethanol %. I bought e85 at the same station for three years and it was always 79-82%. I'm going to check out Twisted Tuning right now.First off, welcome and congratulations!
