Guess I thought I asked a pretty clear question. I know how to edit the
eprom parameters--I just don't understand how the following "commands" are
entered.
D35A 37 START:
D35A C6 4B 38 LDAB #75 ; cut-out mph
D35C 96 04 39 LDAA *$$04 ; status
D35E 85 40 40 BITA #$$40 ; 1 == fuel on in effect
D360 26 02 41 BNE RICH0 ; bra if rich, fuel on
D362 C6 4A 42 LDAB #74 ; mph for fuel back on
D364 43 RICH0:
I realize that the above numbers to the left are the eprom addresses--no
problem. I know how to place C6 at 35A and 4B at 35B--no problem at all.
It's the actual "commanded code" I'm clueless on. If I took some random
numbers and stuck them in an EGR table, I don't think they're going to do
what I want. Does that make sense ?? That's why I'd like to see this in an
ASDU or something--it'll make sense at that point, as I have something to
compare against...
