I'm curious as to the possibility of using an LS1 PCM with the 3800 platform. I know the connectors are the same, but the internal hardware is somewhat different, but there are so many more parameters available, and the tables are considerably larger/more resolute. I don't have an issue with the re-pinning of the wiring harness, but I am curious as to how the timing/ignition system will feed since we use an ignition control module and coil packs as opposed to coil-on-plugs. I haven't the slightest clue if the transmission controls are even remotely close, either, but I am getting frustrated with the ridiculously-small amount of parameters I have to work with. If anyone has any experience or logical theory to share, please do so.
