FYI - only a maximum of 20 points in a cfg file. SCT cannot do more than 20 points. I prefer datalogging with my laptop through the SCT. My tuner seeks 28 points of information. Once the cfg is made its a cinch. Plus the 2.5.X update sync's up much quicker than the previous versions. Data is not garbled, and histograms also make sifting out 411 much easier.
