After driving around yesterday with the stock ECM, I tried one last time today, put in the tuned ECM and did about 6 cycles, car started right up. Ran rough at first, shut it down, unhooked battery, and started it back up. Ran just fine, except engine light was on, which is because of a case re-learn needed. Everyone kept telling me it is a tedious process and you just get lucky. Can't really comment on the tune yet as I've just driven it around the block.
