Shane please do correct me if im wrong....but is everyone saying its better to tune your car on e70 and let her buck with e85 without getting re tuned and one would be fine or get tuned on e85 and once e70 comes around again let her be and you will be fine?. Best scnerio would be to get tuned and have 2maps one E70 one E85 (and a 93 for really bad days) Thankfully ECM LINK V3 Lets you do that
Im a little confused as to which of the blends leans out when one switches over to the other without making adjustments. I assume im safe to say its better to run richer then lean....?
