SM not required for PL, laptop needed for logging the ECM info and for setting up the ports for analog data. Conversely, you could also use an updated SM without a laptop but it would not save the results.
I appreciate the info. I just wanted to know if I put the upgrade chip in the SM if it would work. Doesn't matter anymore because I went ahead and installed the PL and hooked the SM to it. Now I need to do some tuning.
