The basic difference between the V6 16197427 vs. V8 16197427 is the Memcal, the blue thing in the pic below. The Memcal has three functions, PROM Chip, Knock Filter, and Limp Home Mode. If possible, I would try find a 16197427 with a Memcal for the same size engine I am installing the 16197427 PCM to operate.
