re. a chip is a chip is a chip?

[Swann, Benjamin R. (BSWANN)]

Ok - think of it as - a copy of some code is made to a fujitsu floppy disk,
and a copy of the same code was made to a maxell floppy disk.  They are
basically the same as long as there are no errors on the disk.

That analogy follow for several of the code mods for a EEPROM "chip" and is
digital.

But the Zener/resistor mod is not a chip, but an analog modification.  That
is not a chip, and some of the so called "chipped"  ECUs are not really, if
you follow my drift.

[anyone have thoughts or better on wether one companies chipset for the 
5000tq may be better than anothers? or do they all do the same thing / have 
the same parts?

for example - tap vs IA vs lehman vs sjm, etc etc....

thanx!]
