Oh, and the actual bug was that the cold condition ignition table was being looked up wrong. The patch we did shifted the whole table by a couple of columns, so when the car was cold and at low load, the software was actually looking outside of the table and getting bad values for the ignition advance. Pretty simple fix once we figured out where the problem was.

Quick update. Sharif loaded the updated ROM into my ECU yesterday, and I can confirm that the cold start issue is indeed fixed. No more lurching!
