Racer Wholesale air/fuel ratio meter...

[OorQue@aol.com]

I received a flyer from Racer Wholesale -- (800) 397-7815 -- in today's mail 
and they have their "Injector Air/Fuel Ratio Monitor", part no. AUT-9902, on 
sale for $99.95.  I bought a pair of these for my cars last year for $119.95 
each <sigh> and have been happy with their performance.

It actually has two sets of 10-LED readouts, one for mixture and the other 
for duty-cycle.  Although the duty-cycle meter is intended for use with 
electronic fuel injectors, I have successfully hooked it up to the 
frequency-valve duty cycle connector under the hood instead.  This way, I can 
see whether the mixture's running rich or lean as well as how the 
frequency-valve's duty-cycle is being adjusted to correct for it ... in 
theory, this should let me know when I start getting close to the limits of 
the stock fuel system, something that an O2 meter by itself can't do until 
it's too late and the limit has already been reached. 

FWIW, they also have the G-Tech meter (part no. GT100) on sale for $119.95, 
which is the best price I've seen for it in a while...
