Does this work for a cadillac deville 02 instead of taking it to a dealer ? Dash board is on theft and wont turn on or turn over

Depending on the computer output connection, but this works with GM vehicles And Chevrolet; I used to program the computer of a 2004 Silverado 5.3L Vortec Engine. Hope this explains a little about your question.

It's for bench tuning. To tune out of the vehicle. This just connects to your PCM, you'll need HPtuners to do VATS.

what interface do i need to buy to tune my ls 02' computer

HPtuners is the best to deal with for LS engines
