I'm Awesome
Don't hate me or step into that flex fuel sensor just yet with the 4x. I had flex working with 24x. When I swapped to 4x with the 383 I had been running straight gasoline. I had the flex fuel sensor on it but it was stuck at the prvious ethanol % once I enabled it so it appeared to be working. I topped off the tank and the sensor never moved the alcohol %. 4x crank sensor bit kicks my flex fuel sensor off. Tayto and I are trying to find a work around for it. The code is all enabled on the surface, something between throwing the switch for 24x and 4x is messing with it. Its a disappointment for me as well at the moment. The good news is I set the stoich up for the E85, gave it a timing bump above 0.48 gm/cyl and it has never run better than on the P59 so not all is lost.
Mine has not been lean on hot starts.if you are running the marine intake I can send you my latest transient fuel stuff. Its not exactly perfect but it is a heck of a lot better than it was.
