So from what your saying If I fill my empty tank with E85... start it up... will I simply get a lean running motor and therefore lean Lterms? By increasing the duty cycle ~20% will this basically return the Lterms to "normal"? This also should mean the 02's will report Lean with the E85 initially until fuel corrections are made? If this is true Im thinking on production they simply switch to a second (E85) fuel trim table when the 02's report a large amount of lean upon startup/warmup and wouldnt go closed loop until it decidd which table was closer to "normal"?
Im just trying to understand how the PCM knows E85 is in use on the flex fuel carsa and how the 02's react... makes sense if all that is true.

therefore you probably wouldn't get in that situation. its just like building a car on race gas.
