My apologies for not being clear. It has been a very long day at work today. I am anxiously awaiting a foolproof flex fuel option for the S550s. 93 during the week, and E85 on the way to the track, same tune. The holy grail for performance cars.
Will do but it's going to be a while, hopefully this long NY winter comes to an end quick and painless! Lol. Im hopeing to hear reviews from people down south without snowy winters looking to try it out very soon
I think Higgs Boson has a valid point on the need for a flex fuel sensor to be more accurate on the tune. If the tuners(Kind of waiting on Lund) can incorporate a sensor in their tune, I would be on board the next day.
GM computer in his corvette is different then our mustangs. Ford has already built in something silmilar to his aftermarket e85 sniffer. When livernois was able to tweak the ecu to use the factory octane reader that adjusts timing accordingly weather using 87 octane or 93 octane. The computer now with that livernois tune will accept 87 octane any other octane above plus 93 up to e85. It's going to automatically bump up timing until it gets knock then backs off so it can freely add timing now when e85 is added. Their secret lies within 23 thousand different tables in the Ford ecu. Just my understanding of how it will workI think Higgs Boson has a valid point on the need for a flex fuel sensor to be more accurate on the tune. If the tuners(Kind of waiting on Lund) can incorporate a sensor in their tune, I would be on board the next day.
The E85 sensor is not aftermarket, it is a GM part. Some vehicles have used the physical sensor and some use a "virtual sensor" which is what is being discussed here. If the Ford ECM has a Physical Ethanol Sensor, can you provide a part number for it? A physical sensor is not a wideband. The GM virtual sensor setups simply used fuel trims to detect Ethanol by using the oxygen sensors, just like Ford.
Still don't know how this black goo forms and why it does. Would like to know this but no one really has an answer for this.
More then likely when a car wasn't set up with stainless fuel lines all the way into the engine compartment and has rubber lines they crack and deteriorate from the inside causing this. I believe our mustangs are stainless lines all the way to our engines so it shouldn't happen
Any way to confirm this?
My cars in storage right now but if I had it I'd be checking in the,engine compartment if the lines are stainless. I have seen ethanol breaking down rubber lines and causing clogged carbs from it in machines stored too long, I'm sure a car would have the same issue from ethanol with rubber lines. May be why we all may have heard of stories of other cars having clogged injectors or fuel filters. I have seen cars with stainless lines in the underbody but once in the engine became rubber for flexibility
