Car Motor + 486 cpu = clean air ?

[Richard_Cranium72]

Old Mechanics never die, we just rust away. Get a 486 or whatever(<$50) add in some junkyard throttle body fuel injectors, and sensors.. Have any motor-heads used an old pewter to get a oldie or street car updated ?? DrVette

[Richard_Cranium72]

Several MotorHeads here outta be able to figure out how to mate a pewter to a fuel injected car engine..

After all the environment will benefit.

So will the wallet..

LOL

I think you'd have better luck taking a fuel injected engines pewter and upgrading a 486!

Err, are you aware as to what NASA uses on the Hubble Space Telescope ?

I'm in no way knocking 486 there DrVette, merely stating my opinion that a fuel injected engines fuel management is pretty darn complicated. I've learned that from 30yrs of being a tuneup tech at GM dealers.
No offence was meant, and I hope none was taken!

Not that complicated - not that many processes, but perhaps very fast in real-time these days.

30 years experience is impressive but I hope the whole time wasn't spent as a tuneup tech.

The first GM microprocessor controled fuel management was C3 back in 1980 -wasn't it? anyway, only 20 years ago I believe C4 followed in 1981 (a more fully computerized combustion system, perhaps the worst, most horrible performance decrease in history)? Meanwhile, even then Bosch fuel injection was light years ahead of the game.

It seems to me that a 486 might be struggling to handle things in a modern vehicle. I'm a little out of the loop, but I have heard (rumor) that 200mhz RISC chips are used in current GM ECMs

BTW - Richard, I think there are some nice after market fuel injection kits (Holly?) that are even emissions approved.

DFI fuel injection systems are programed and reprogramable with computers...does that count?

If you will note the date of my 1st post, It was a year ago http://sysopt.earthweb.com/forum/smile.gif

Naw Biff, no offense.

I think if a 50-100mhz processor could align the Space Telescope, it could handle;

1. Mass Air Flow
2. RPM
3. Manifold Absolute Pressure(Vacuum)
4. Oxygen Sensor feed (mv)
5. Throttle Position Sensor
6. Vehicle Speed Sensor
7. Engine temp
8. Air inlet temp

The deal of a Holley is OK, but to get a unit with a Oxygen sensor will cost about $1200

I got a pal with a auto recycling business and the throttle body injectors and other pertinent hardware would be cheap.

I want to set up a dual throttle body on my boat.

It's a Glastron Carlson with a 1968 327 Hi-Po engine.

Probably wishful thinking, but after a year and 3 days, the desire is still there http://sysopt.earthweb.com/forum/smile.gif

think on it car buffs,, btw, where's caddmannq ?

You might try a post on the alt.autos.rod-n-custom newsgroup. I know some guys over there were working on such a project about a year or so ago.

actually, a typical computer out of a car is smaller ind less weight. you can get a comlplete system for a small block chevy from a junkyard or even by buying a totaled car from an auction for the measly sum of $100. a newer complete system will bolt directly on to your 327 and will likely be more waterproof than a 486 computer. i have picked up a complete mercruiser port fuel injection system for a big block 454... injectors, manifolds..everything ..... for under $500 at a local marine flea market.
unless of course your'e just looking for a challenge.......
