Are you implying *only* V8s are worthy of tuning?

It's my understanding that the analogue RFD calibration circuit, 
aka. NetRes, or CalPac, work irrespective of MAP vs MAF, and they
only "work" in limp home mode.

OTOH, the FMD determines the cylinder count from the NetRes too,
but, as has been pointed out before, the NetRes's cylinder count can 
be changed with an extra resistor across two pins of the MemCal.

The knocksensor signal conditioning circuit ("ESC circuit") should 
be specific to a motor and/or the sensor's placement.

I have some 4 cyl MemCals that are brown.
