Is there a way of getting a copy of a car original calibrations. The car is a VZ SS, and doesnt have the original PCM installed, but a mail order tune that doesnt have the original calibrations for speedo, fuel etc. Can you somehow get Holden to give the info to you?
Most of the items should be able to be calibrated in service by a tech. Check the setup mode of the cluster. In the Caprice, you can adjust most (fuel, speedo etc) settings. Might be able to in the SS as well. Involves monitoring the fuel use and also measuring the distance travelled. Haven't bothered to play with it myself, had no need.
