I know i have seen before that some years between 03-05 were flex fuel compatible, is flex fuel the same thing as E85? Also besides the PCM is anything else different on the motor?
My thinking is that I could pick up one of these flex fuel ecus and then my car would be able to run on E85, thats my ultimate goal, is this possible

are you gonna have it installed at pepboys?
I am fairly certain there was never an E85 Cavalier. The "flex fuel" vehicle you are probably referring to is actually "bi-fuel", which runs on both gasoline and CNG. A conversion is completely impractical, not to mention you would not receive any of the government benefits if you don't purchase the car already set up as such.

I did a quick search on google and I couldn't find anythingthing. GM has a web site called
gmaltfuel.com that lists all of their current alternative fuel vehicles and the only sedan is the impala/montecarlo.
I also found an article about someone wanting to convert their 2001 Cavalier to E85....
Q. Could I convert my 2001 Chevrolet Cavalier to burn E85 fuel?

A. The long answer to your short question: Unless the car is designated as a flexible-fuel vehicle (FFV), there are no guarantees you won't experience a problem using fuels with more than 10 percent ethanol. Still, some people claim to use up to 85 percent ethanol (E85) in their vehicles, garden equipment and boats without problems. Ethanol burns differently than gasoline so the check-engine light may illuminate. Carbon monoxide, hydrocarbon and oxides of nitrogen emissions may go up. Chances are you would fail the emissions test.
Doing a conversion to make a standard gasoline-powered vehicle ethanol compatible would involve making sure the fuel system seals and gaskets (elastomers) can tolerate alcohol.
If they can't, the fuel pump and related fuel system parts (fuel rail, pressure regulator etc.) may fail. Rubber parts swell and ultimately fail when exposed to too much alcohol. Alcohol also may attack metal parts not suitable for such exposure. Such parts would need to be replaced with E85 compatible parts.
Short answer: Probably not.

anyways im sure it can be done there was a guy on TV with an old 60s impala running e85 he did the conversion

i have taken an alternative fuels class and know that it can be done, although a lot of work would be involved. i guess it is the same situation as someone asking if motor X will fit in a cav, anything is possible with money and research. you just have to weigh the pros and cons.
