I know there have been many people asking about doing an engine swap in the LS and about all the problems it brings about. Mainly, there is the problem of two computers and how they cannot interact. For some time now I have wanted to do a complete rebuild of an LS including an engine and transmission swap. While I am still at least 2 years off from even considering doing this, I have started to think about it. Mainly about this very problem.
I am a computer and electrical engineer and have made interface circuitry for smaller systems before to control all sorts of things. I was wondering if I might be able to work on some type of interface between the LS's onboard PCM and whatever system comes with the new engine. To do this I simply need to know some of the specifics of what the PCM expects to see and I would essentially trick it into thinking everything is fine. In the mean time the proper control of the engine would be done by the other computer. If there is any shread of possibility in making this work, I am interested in taking it head on and developing this. If anyone knows anything, please let me know. I imagine this will probably take 1 or 2 years of development and testing and I am willing to go through with it.
