O2 sensor display.

[Regnirps at aol.com]

Hi all,

I have put together an O2 sensor or fuel/air ratio display with 20 lamps and 
automatic dimming. I'm thinking of selling them and need some feedback. I 
have put up a sort of business looking section on  my website at

www.regnirps.com

to describe them and I have what you might call a beta price point. I made a 
batch for tuning for some local racers and am thinking of looking for a 
distributor or just web sales.

I would like to know what people think of:

1) Price
2) Form factor. Is the rectangular unit too hard to mount?
3) Would you definitely prefer 2 1/4 inch round instrument style?
4) Would you like a dual unit (I use one for each header, so would like a 
dual myself).
5) Would you like a combined mixture and manifold pressure unit?  Mixture 
lamps are moving dot, manifold is moving bar.

I have noticed users have definite preferences about the speed of response of 
the device. The O2 sensor is very fast, you can see individual cylinders on a 
scope or with an unfiltered display. This "jittery" look bathers some people 
and I put some filtration in to give an average and smoother readout and it 
is easier to see things like your system response to a big throttle input -- 
it slams lean then swings rich, etc.

Any input appreciated, meanwhile I will be lurking since I want to pick up 
ideas on how to do some stuff to my old 11/1 compression ratio square port 
396. I have been thinking of a totally home grown electronic system with some 
kind of injection.

Hey, does anybody make a combination spark plug/injector?
