Re: Engine module firmware update
Some really good mechanics in the area have tested for and advised that an Engine Module flash (or EPROM update) is available for my 1997 Riv. The price of the software is $75 plus labor (electrical installation.)
Wow....our shop never handled it that way, as far as I remember(Buick Dealership).....if you came in with a driveability problem, and an update was available to fix it, we would charge you for diagnosis time, and the time that it took, to hook up our computer to the vehicle, to download the new program, and any other extra programming that might be necessary(like a crank variation relearn)........it was all labor, and I don't recall a charge for the programming......especially since the programming might have been a necessary fix, due to a flaw in the original programming....
