Smart Plugs Ignition System?

[JShadzi at aol.com]

Ok, granted, the list you just created sounds like an impressive argument, 
but lets look at them one at a time:

- Failure - IME, the CIS3 ignition system is incredibly reliable in stock 
trim, and with reasonable and affordable tuneups ever year or two, there should 
really never be a problem.  Also, for the approximated cost of the system 
($1400?), you could do an awful lot of tuneups.  Fouled plugs have also never been 
a problem IME.

- Leaner Mixtures - Ok, leaner does not mean better MPG or better efficiency. 
 The point of the Stoichiometric ratio is that it is the point of max. 
efficiency in the gas 4 stroke engine.  I have read a study recently that showed 
15.2:1 was, under certain conditions, more efficient.  With the Stage II 034efi 
system, I can tune my 80 to run down the freeway at 18:1, but it will actually 
get worse mileage, thus I tune it right to about 15:1 under part throttle 
cruising.  Detonation isn't a problem typically unless you're under full load.  
Now, if the SP system can run your engine at 30:1 a/f at a greater efficiency, 
then it sounds, as you said, too good to be true, or I don't understand it and 
I encourage you to research it further.

Overall, your assesment sound too good to be true, so I encourage you to 
contact them and verify if your understanding is at all reasonable.

Looking forward to hearing what they say.

Less failure points. No ECU and wiring, no distributor, no cap, no rotor, no 
plug wires, no timing problems, no fouled plugs. Plus as he said you can run a 
MUCH leaner FA mixture (1:30?) with no detonation. Wouldn't you like to dial 
back the fuel to 1/2 what your using now for long highway trips? yeah, it 
would cut back on power, but imagine being able to cruise in your Audi 4000q or 
other NA I5 powered car and get 40 MPG on the highway, then when you get to your 
desination you crank back up the fuel for full power driving. I'm sure the 
engineer who spoke up a little while back can explain how timing is done, but it 
appears that timing is done properly, including advance.

My question exactly, what would be the point of implementing an product like 
this in an otherwise stock (or mostly) CIS3 car vs. going with a proper, full 
control engine management system?
