2D Pro-Jection O2 sensor

[Fitzgearld, Fredric]

Nope.  This system is definitely not Speed Density.  It uses the TPS and 
tach signal for reference.  The one thing I'm curious about is what the 
O2 sensor controls.  Does it move the whole "map" like the "main" knob 
does?

>All,
>I got my 2D Por-jection (502-20) system late last week.  Inside I found a
bunch of resistors, a PROM, something that that might be a processor (a
small square chip), and what might be a driver chip.  Holley painted over
the tops of the 2 chips that were not the PROM.  I'll look into getting the
numbers, later.
Now, for the question of the day:
>Do any of you have a wiring diagram for what plugs into the 6 pin plug?

sensor and the ECU?  If the sensor goes directly into the ECU, what pins do
they go to?

Did the system include a map sensor?...
Inquirin mindless gotta no..
