1. Dynojet Power Commander V Auto Tunner

Dynojet Power Commander V Harley Davidson Touring Models

Dynojet is one of the most popular brands when it comes to motorcycle performance tuners. I decided to try out their Power Commander V model for my Harley Davidson Touring motorcycle. After installation and a few adjustments, I have to say that I’m really impressed with the results.

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.

Also, if you wish to map your bike’s performance based on different situations, the gear and analog input functions are really beneficial. For example, by having this Harley Davidson tuner, you get a different fuel map for city riding versus highway riding. 

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.

When it comes to compatibility, this tuner is ideal for 2002-2006 Harley Touring Models. So, you don’t need to worry more if you have these models then this tuner perfect match for your Harley Davidson.

I’m very happy with the Dynojet Power Commander V as a whole, and I’d recommend it to anyone who wants a good performance tuner.
