DIY LTCC or similar system for LT1s

Fast 335,
Sounds too expensive for me. $1200 just to run like it normally does anyways. Add to that obd2 tuning program and programmer for the new ECM to get it running right for another $1000 + time. I could simply drop in a LS engine and computer instead.

My ulterior motive is to make my ignition system into an ion sensing ignition system. That way, I can directly measure cylinder pressure and produce the most optimal spark timing for any condition on the fly. The optispark signals will need no decoding to produce a 1 degree accuracy for my system. The LS system provides me with no such decoding output that I can splice into.
