- GM also has a sensor in the fuel line to measure the mix of alcohol and
- gasoline in their flexible-fuel Luminas; I don't know what the technology
- is. However, at last year's Alternative Transportation Expo in Burbank, CA
- (I think), the California Renewable Fuels Council had an ethanol/gasoline
- Lumina that came from the factory, so GM evidently has the ethanol calibration
- in hand for their sensor.

- For us knuckle-draggers out here, does anybody know of a vendor, or at least
- a reference telling how to modify a stocker, for a carburetor to use
- single-fuel alcohol (eth or meth) for the _street_? I know where to get
- full-race Holley double-pumpers for methanol, but I'd just as soon have a
- transition circuit and a few other frills if it's all the same to you...

- [Stoichiometric mix for ethanol is 9:1 (methanol 6.45:1) and makes
- much more power if fairly rich so you need to figure at least twice
- the flow as a gasoline carb. I think Barry Grant Fuels here in
- Georgia has a paper available on the conversion (see Dave's vendor list)
- I'm pretty sure Kinsler Fuel Systems (see ditto) does. Lean alcohol
- detonates rather violently so you MUST make sure you stay rich of
- stoch. JGD]
