The program used is written to communicate specifically with the chip that is the heart of the Holden cluster. It would have no idea how to communicate with any other vehicle's cluster.so aside from the gto's this doesn't work for any newer cars? Would it be possible to switch the solder points to make this work on newer cars?
And if you're talking about something beside the cluster, then nope.
Slow mentioned the 94 LT1's because this cable is designed to communicate with the ALDL bus, which if I recall correctly is what basically everything on the LT1's communicated over, including the ECM.
The ECM's of newer cars doesn't communicate over ALDL. Our cars have a powertrain interface module to talk between the two busses, to communicate with the the ECM.
