I just looked around Twisted Tuning and am sort of confused. I couldn't find a discrete tuning package for the Supra. They show custom tunes for $450 but there is no mention of how the tunes are uploaded to the ecu. They also show an ethanol content sensor but I don't see how that integrates...
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.
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?
