So my question is, it sounds like the fueling will be adjusted by the proflex commander but what about timing? If I give it 20 deg on full e85 but then fill up on 91, won't it will have 20 deg if timing?
I noticed that in hp tuners that there was an option in the is for flex fuel. So I need to perform the os swap?
Thanks.
