I don't know what you said  8^)  .....  but, the Holley 502 ProJection
system is about as low as you can go .... uses only TPS, RPM and temp
as sensors (and you could leave off temp if you wanted).  An option
is available to add EGO feedback -- which, I've found, is necessary
as there's a lean condition when holding TPS constant (i.e. neither
decel or accel) and dropping engine speed (RPM) -- e.g. when
climbing a hill.  A very lean condition results (same thing occurs
when slowly opening up the accelerator -- lean until RPM comes up).
