E85 for 94 Saturn
What would it take to get a 94 or 95 SC2 to run on E85?
Change in Fuel Delivery? Modified PCM? E85 is now available in my area and its CHEAPER (not cheaper ENOUGH, though)! -WaVy |

Considering my amount of underside rust I have, I didn't even want to look. I'm just guessing what type of materials must have been used in my 97SL2. later, tom @ www.WorkAtHomePlans.com |

E85 for 94 Saturn
Didnt find anything very hopeful on the "emmision test" qualifier.
Seems that our wonderful government makes it illegal to install aftermarket conversion on non E85 vehicles. On the other hand... (who's business is it what I do under the hood as long as I can still pass emission tests!!!) I mean - will the EPA police be parked somewhere near the E85 pumps, watching for ethanol anarchists?! The only possibly definate I found so far is a kit from http://flextek.com/shop.htm I think its built in Brazil. Dont know for sure if it is plug/polarity compatible. It has a remote alcohol/gasoline switch. Polarity inversion kit is $90. Four cylinder wiring/computer kit is $516 (WHEW!) I have no idea if the plastic Saturn fuel tank, fuel pump, or fuel lines are E85 Ok. (Anyone?) I assume that the "brain" in the FlexTec unit works with the original PCM in a way that emulates the volumetric equivalent of gasoline, but controls the operation of the fuel injectors autonomously. (I guess that should work!) Unless the cost advantage of E85 becomes more significant though, I dont think the cost of converting would be economically feasable. -WaV Phil Marshall wrote: > "wavy" > wrote: > > > What would it take to get a 94 or 95 SC2 to run on E85? > > Change in Fuel Delivery?

As an individual doing a DIY swap federal EPA regulations are of minimal concern. The Federales have never prosecuted a DIYer for violations yet. Passing your State regulations if your state has inspections is a concern. E85 does not present a problem to metal fuel components but it might to various rubber parts. Most rubber parts in cars today are largely ethanol proof, but you might consider upgrading any flex hoses and fitting a good prefilter to the initial fuel point (somewhere before the fuel rail). The bottom line is that on straight E85 you are going to have to flow roughly 40 percent more fuel, and the fuel/air ratio curves are going to be different. If you can fit an E85 sensor compatible ECM and the sensor and retain a factory harness, and somewhat larger injectors and come up with an appropriate map, you are okay. Otherwise you are going to have to use an aftermarket ECM and probably again different injectors. One conversion for VWs kept the Digifant EFI and added a GM TBI unit that ran either gas or ethanol simply by enabling or disabling the TBI injectors. If you are going to run straight E85 all the time, a quick fix might be to get the engine running open loop and put in injectors that will flow 40% more than the stock ones. Many domestic and foreign ECMs have "secret" open loop modes for vehicles sold in leaded fuel markets which can't use a cat or O2 sensor. Converting to an aftermarket mechanical FI or, Ghod forbid, a carb makes the whole thing simple: just jet appropriately. Problems include: if you move to a inspection/IM state, sell the vehicle, or they quit selling E85 you need to convert back. And economics: E85 is no cheaper by heat value! Easiest cheapest way to run E85 is buy a old simple motorcycle or VW Bug with a single carb you can rejet, replace all the rubber, slosh the tank and be good to go. |

None of the racing cars running methanol used stainless fuel lines, and I don't think E85 factory cars do either. Actually stainless steel is a poor choice for fuel lines for reasons known to anyone with P&W or GE jet engine experience. I wouldn't worry about ethanol too much in terms of materials compatibility on modern cars. Methanol is a different issue. |

Big differenc between a racing car that sees litle usage and lot of overhauls and a daily driver. It will corroed plain steel lines with time. Just look at the metal fuel lines on a E85 car and you will see because Detriot would not waste money on SS fuel lines if it was not needed. ----------------- The SnoMan www.thesnoman.com |

E85 for 94 Saturn
After looking over the following data, I've concluded that E85 EXISTS
only so that the current bureaucratic slimeballs of stupidity can claim that "They are doing SOMETHING..." (when the current unsustainable situation is just fine with congress and the PREZ & the big oil connections) http://www.fueleconomy.gov/feg/byfuel/FFV2000.shtml Your vehicle would burn SO much more E85 than straight gasoline, that you'd save money by spending $3 per gallon of gasoline than spending $2.50 per gallon for E85! Lets suppose your car gets 25mpg driving to work and back every day. At $3 per gallon, that's 12 cents per mile. Your 25mpg car MIGHT get something like 20mpg on E85. At $2.50 per gallon, that's 12.5 cents per mile. So 10,000 miles later you'll have spent $1200 on gasoline or $1250 on E85. You havent saved SQUAT. (and the 20mpg on E85 in a car that otherwise would get 25mpg on gasoline - that might be with a tailwind mostly going downhill) For E85 to be cost effective, it would have about 2/3 (or less) of the price of gasoline. -WaV > > When I asked about usind e85, and wondering the requirements, I was > told I had to have my car's fuel system fully stainless steel. > > Considering my amount of underside rust I have, I didn't even want to > look.
