does there exist such a thing? (switching fuel and computers on the fly) been reading on Nitrous oxide kits for me and my bud's turbo minivan and some of the things these kits do got me to thinking about some "innovative" ideas to do with my LS1 engine-
there was a kit that had a 2nd fueltank that your fuel lines would switch over to when the Nitrous was engaged- The theory was that you'd have 103 octane in the spare tank, and wouldn't have to constantly waste money on high octane fuel when you were driving daily.
My idea
what if I had 2 tanks in my car-one with regular fuel and one with high octane (103 for example), now what if I had 2 computers for my engine, one that was tuned for the regular fuel tank, and the other for the high-octane fuel tank. I'd just flip a switch, and I'd be on a higher-octane fuel AND have the engine's comp tuned for that high octane.
It'd allow me to save money on $$ when I'm weekend cruising, and with a flip of the button, I'd be prepped for the race track or rice eating 
is this just a crazy idea, or has someone done it already? I can pick up an ECM from a 2000 TA at the 'yard for $60 and one from a 99 Camaro z28 for the same price. I was an electrical engineer at my early stages in my college career, so wiring up a switchboard to computers wouldn't be beyond my skills. switching fuel lines and fuel tanks on the otherhand is beyond my current skills as I have no idea how I would go about doing that.
right now this is just an idea, with no real motivation to develop it beyond exercizing my creative and fabricating skills, but hey, if people think it can have a use, I might add it into my longterm plans for my hybrid.

No need for dual fuel tanks and switching, why wouldnt you use a dedicated fuel system for the nitrous like so many other people have and run race fuel through that??? As far as computers go, the wiring would be completely nuts. You would have to have dual sets of wires to all sensor, fuel injectors, coils etc etc. So each computer would do the same thing Or maybe a piggy back setup witht the computers. For the money and time involved, i dont think this setup would be near worth what it would take to accomplish it. IMO Good luck if you try it.

I know two guys in MN who have done that, they have manual switches/valves by the side of the driver's seat. Sounds interesting but I'd need a full write-up of the setup. SleeperZ or SleeperZ28 in the FI forum of www.camaroz28.com has that setup.

I know my friend has a 1996 mustang cobra. It has the kenne bell S/C and he just installed something that will shoot "windshield washer fluid" in the piping for the S/C and cool it down ALOT. It was called something like methonyl nitraide injection or something. It takes pump gas and turns it into like 110 octane and cools the blower down. Im just trying to go off of what i remember. But i could be wrong. anyone else heard of this?
Let me know.
