GMECM Digest V2 #754

[Swayze]

Gary,
welcome to the list.

have you perchance taken a look at the .ecu files for some of the known

list a lot of the code locations for some of the 'variables'. also of
interest might be the p4.doc--not sure if any of the locations of
'factoring' constants would be viable though. The aldl stuff for the earlier
ecm's is there.

the J- documents may have more of the info that you are looking for as to
OBDII specs.

'in digest mode'
