Charles,

I have not written the program, so I can only assume what display colors mean.

255 = $FF values are highlighted for a unknown reason
white: table entries defined in .ECU file
cyan: any other bytes

Making an .ECU file, which is different for the most different ECMs (an ECU
for a 1227730 does not work for the 1227747), is quite a complicated
process. I made an .ECU filefor the 7730 ECM (to be found at
http://pweb.de.uu.net/pr-meyer.h) by browsing the disassembly of a 68HC11
ECM PROM from diy_efis ftp site. You have to know where all the tables and
constants sit and so on.
Mit freundlichen Gruessen
