As y'all know, I have a Harley, and Harley do a wonderful product called a Pro Super Tuner from the Screamin' Eagle performance product line, which allows you to remap and tune your ECU (at the small fee of £450, cables not included!)
I have one of these lovely tuners (not at that price though
) and I have the software for tuning, and thought I'd share a screenshot of just how wonderfully simplistic it is to adjust the tuning. You just select the area you want to tune on the left column, highlight the values you want to alter, and then just click increase or decrease. Easy as that!
