Ok. Been a long time and found some time to get back into this stuff again. This time I managed to
source some things and build a bench harness to read the PCM here on my better PC.
It seems to work and I can access both the ECU and TCM here when in the car I could only read the ECU.
Before I could only get mappings for what trans is installed and whether its 4 speed or not. Now I can get
that plus the shift schedule. Which seems to be pretty limited and generic too.
The problem now is that there are no mappings to DTC's or anything with the trans itself.
Is there more to this or am I asking too much??
