Exactly how will you know how lean the bike is when tuning it? I am not very computer literate, and am interested in the product, however, the description does not really explain to me how to use the device correctly. I am confused on how you go about tuning it considering my bike is 2010 Honda with no O2 sensor....


You will not know how lean the bike is in terms of a measurement, like 14:1 or 15:1 air/fuel ratio. We develop the suggested tuner settings by testing the power on a dynamometer, using air/fuel measurements over each throttle position, and all the rpm ranges.

You will know that we only allow a fuel adjustment range that is not going to be excessive or harm your bike, and that this is using your stock EFI map as a starting point to make changes.

The Power Surge tuner has 6 color/zone adjustment features, each with it's own setting. The light #3 in each color zone is going to use the stock setting, and pass the same signal directly thru to fuel your bike. When the setting is lower, like 2.5, 2, or 1.5, then the jetting is leaner. When the setting is increased, like 3.5, 4, 4.5, 5, etc, then the jetting is richer.

Each model of bike has a recommended list of settings to use for correcting the stock map, and then you can add or subtract fuel from there as you feel works best for your motorcycle and conditions. If you feel the mid-range power might benefit from an adjustment, then move the mid-range (yellow) light up or down and go ride to see how it works. The changes are VERY EASY, and VERY QUICK to make. You can easily try a richer setting, and then leaner, for a comparison.
