Found a copy of the ignition wiring diagram over on lt1swap.com. Guess now I just need to get my head wrapped around what kind of signals are being sent to / from the different type of ignition modules. I am optimistic that GM didn't change things too much.
dave - I don't deny that your method would be more ideal, I am just trying to make something work. You can blame it on my mind wandering too much these days, and the fact that I have an old 91' TBI engine still running the stock ECM. This combined with me playing with / having the 0411 stuff laying around, and it makes me wonder if I could just do a quick and dirty swap. I have swapped other LS stuff, so I am familiar with making the 0411 stuff work in standalone-ish type environments. Granted this was done using my EFILive ... but that learning has shown me how to dig into the OS, and doing CAX's for things not supported.
As for the fueling side, I understand the differences between high / low impedence and am familar with how the TBI fueling works compared to say a Vortec / LS. My hope is that an old school method of either adding resistors in series would suffice, or maybe just wiring 4 of the injectors together into one of the TBI injectors would also work.
The different tables / maps are not a big deal. The 0411 can be made to work in SD mode. Yes, the tables are little goofy if you haven't worked with them before, but its not a show stopper.
