DHM Reflash and Camshaft Package (Stage 2)

***Update 6-3-24, The Decha HR camshaft has been added as an option. It provides the same gains as a TB or DCR R2 but with a different lobe design that is not as noisy due to a larger base circle diameter. 

***If you already own an aftermarket camshaft you can still purchase our Reflash for those mods here: https://www.dhmotoring.com/products/stage1reflash

****DOES NOT FIT THE 2022+ HONDA GROM/MONKEY, for the 2022-2024 model, click HERE

If your Grom already has an intake and exhaust, this is the next step!

We've created a camshaft package that allows you to add a Decha HR or TB Parts camshaft and our DHM Reflash to your bike. This will add as much as 2-3hp and will also increase your rev limit to 10,000 rpm, while also correcting the fuel and timing tables in your ecu. Your Grom will experience much stronger high RPM power, as well as the ability to pull to higher RPM before shifting. After tons of dyno and street testing, we feel this it the best bang for buck upgrade available! 

Benefits:
Corrected Air/Fuel ratio for your exact modifications
Increased ignition timing for throttle response and HP
13+ HP depending on your intake and exhaust setup
10,000rpm rev limiter
Normal cold start functions (no bad idle issues when cold)

Included: 
DHM Reflash (more info here)
TB Parts Camshaft or Decha HR Camshaft

***Each tune is catered to your exact modifications (intake, exhaust and cam brands, etc.) After checkout you will receive a link to an online form that will ask for your bike's exact setup so we can tune it accordingly.

You have two purchase options for delivery. Once you've completed the purchase, we will email you with instructions on sending your ECU in to be reflashed. You can also choose to purchase a core ecu, we will send you a flashed ecu and you can return your original one and receive a $50 credit or keep it as a back up.
