GM ECU questions

[deadscoob]

Hi All,

After a bit of info on GM ECUs, does anyone know the following:

Are they the same for LS3s and 7s
Is it possible to see a time stamp when the ecu is flashed, and does it log each time it is re-flashed
Where can I get replacement ecu plugs from (those that physically plug into the ecu itself)

Cheers

Thanks all
