Buick 3.8L SFI

[Jenski, Leonard]

Hello All,

Does anyone know where I can obtain the specifications for the data stream
information from the PCM for a Buick 3.8L SFI used in a 1994 Buick LeSabre?
I am in the process of implementing a POC based scan tool but I need the
data stream format/brteakdown to identify the data. Can anyone help? Forcing
error codes is one way but it only identifies part of the stream.

Also is there any information on how to comunicate with the body and chassis
(ABS, TRACTION CONTROL, etc.) modules on the same car?
