Start with the first thing you’ll notice, which is the size. This tuner is a lot smaller than the PCIIIusb model, so it won’t take up as much space on your bike. Moreover, due to the USB power, you don’t need an external power source because it allows you to have a device that works directly from your computer. So, if you’re looking for a more streamlined installation, this is the tuner for you.
This tuner lets you adjust the air-to-fuel ratio, ignition timing, and maximum RPM so that your motorcycle runs at its best. This gave me much more control over my bike’s performance, and I was able to get the most out of my modification.

The built-in ignition control is especially useful because it lets you change the timing for each cylinder. This was quite beneficial in making my bike run smoothly and decreasing engine vibration.
The second thing you’ll notice about this tuner is that its mapping function has been improved. You can fine-tune the air with this tuner, which protects the engine of your bike. Now I’ll talk about how much this item costs. Compared to other brands on the market, it’s very cheap, and it’s in your price range.
