Labor Day sale is live! Today only until 12am PST. Select products only, click the banner on the homepage to see the sale collection!

After over two years of development, we are now offering a way for you to flash your Honda Grom, Monkey or Dax from home!

This system does require a Windows based computer, but will allow you to store multiple tunes to flash at your convenience. You can flash back to stock, upgrade to a different setup, etc all from your own computer. Our cable will lock to your ECU once flashed, but you will be able to write as many files as you'd like to it over time.

When purchasing any tune on our site, you'll now see the option to select the DHM Flashing Suite Cable as an option! Mailing in your ECU is of course still an option to keep the tuning economical.

Happy 250th Independence Day 10% live sitewide until tomorrow night. Must use coupon code “JULY4TH” at checkout.

I don't post private affairs on the DHM page but this hits hard for me.

My good friend recently lost his wife and the mother of his two young children to cancer. As hard as it is to imagine going through this emotionally, there is also a financial toll that can't be overlooked.

JT is a personal friend and a professional partner as well, and is responsible for helping to manufacture many of the parts you've come to know and love us for!

If you are unable to donate directly, please consider them for any fabrication, manufacturing, design or consulting you may need in the future. They are the best in the business, and a quick browse of their social media will confirm that. They are extremely well versed in modeling and CNC operation (two 5-asix machines in house) and on top of that they are true gearheads with performance-engineering backgrounds that rival the best of the best.
