the problem is that alcohol is hydrophobic, so it'll cause the moisture in your gas tank and gasoline to separate, and it'll end up pulling that water into the fuel pump. i'm telling you the pcm looks for lamda, but you can reset the value it's looking for. you can tell the computer that lamda is 9:1 and it bases all it's calculations off of that.
Ethanol may degrade some compositions of plastic or rubber fuel delivery components designed for conventional petrol. U.S. "FlexFuel" vehicles have upgraded fuel system components which are designed for long life using E85. The cost of this E85 upgrade to a modern engine is inexpensive and is less than $100. "Total Flex" Autos destined for the Brazilian market can burn E100 (100% Ethanol). Ethanol has 27% less energy per litre than petrol.
Methanol is even more corrosive and its energy per liter is 55% lower than that of petrol. Higher compression ratios and corrosion-resistant materials easily overcome these issues, and require modest engine modifications with known technologies/metals such as stainless steel. Given the higher octane rating of Ethanol, forced induction engine architectures (Turbocharging or Supercharging) with modern sensors, actuators, and computer controls are capable of generating equivalent or higher horsepower and torque burning ethanol than conventional gasoline despite the lower energy density of Ethanol.
So let that be clear, that what your talking about is NOT Ethanol but Methanol...
Confusion is what leads to all the mis-information.
The SRT-4 is a MODERN car and will work with E10. Modern E10 cars have been tested and are running E85 without any long term issues. Michigan State put 100,000+ miles on a late 90's Tahoe, pulled it apart - NO DAMAGE
The focus here should be how you make sure you car doesn't LEAN on on the stuff, not that it will break down every fuel component in your car, which WON'T happen.
There's people on the Neon.org broads with Megasquirts running E85 without any issues other than upgraded INJECTORS and PUMPS.
In the end, Mopar will not honor you warranty unless it was a Flex Fuel car, which they build to make sure it will handle E85 for 100's of thousands of miles. I sincerely doubt you'll have your SRT-4 longer than 7-8 years and less than 150,000 miles. Considering you have been running your car on petrol since you bought it, the chance of your fuel system degrading in the 40-50K window you'll be running nothing but E85, NOTHING WILL HAPPEN!

finally someone did some decent research. I posted similar info in the fuel section a few weeks ago to try and get some of the disinformation out of here.
I'd like to find someone to write me an E85 SCT map, dunno who can do it.
I was waithing for someone to post this
FYI
All the modifiers are avaible via SCT in the ECU to run Ethanol.
Spark, Fuel, Idle, Start up,,,ect its all ready to go,,,,, for the most part.
All thats needed is to figure out the feedback signal from a stock "Ethanol" sensor.

i'm saying, i wouldn't have a problem filling up with E85 and flashing. And then when i switch back i'd have to flash again.
Explaination:
For the SAME reasons all engines use O2 sensors to constantly feedback the O2% to the ECU, an E85 engine, flex or not, should use a sensor to feed back the proper amount of Ethanol and Gas. All ECU are programed to the Nth degree and OEMs spend a few MILLION DOLLARS doing it ,BUT they still rely on an O2 sensor to correct the A/F. There's no need to try to comprehend the engineer's reasoning, just accept the facts.
% Ethanol will never be consitant. Even the small bit of gas left in the tank will throw it off. % water that WILL find its way into the tank will throw the tune off. Whatever some who-ha tuner "programed" will never be quite right. Even IF he knew what he was doing. IMO by what AGP and other "Tuners" are doing to hack job programm the NGC, I'm not optimistic that anyone will get you a comprehesive(cold start, idle, part throttle accel, ect) E85 map without actually using the NCG like it was design to be. Well, I'd trust Neil if he also handed me a E85 feedback sensor.
Bottom line: Let the ECU work the way it was meant to. The ECU needs the proper feedback from the sensor to appropriately modify all areas of drivability.
