DHM Stage 2 Flash and S1 Cam Package (2022+ Grom / Monkey / Dax)

$329.00
ECU Core

 

If your 2022-2025 Grom/Monkey/Dax already has an intake and exhaust, this is the next step!

We've created a camshaft package that allows you to add our S1 camshaft and our DHM Reflash to your bike. This will add as much as 2-3hp and increase your rev limit to 10,000 rpm, while also correcting the fuel and timing tables in your ecu. Your Grom will experience increased power across the entire rev range, 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! 

Features:

  • Corrected Air/Fuel ratio for your exact modifications
  • Increased ignition timing for throttle response and HP
  • Modified injection timing for ride ability and response
  • 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 S1 Camshaft
  • DHM Reflash for the S1 camshaft and other modifications

***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 $65 credit or keep it as a back up.

Exceeded my expectations

Stock, the Grom is slow and not fun to ride. But after an exhaust, intake the DHM Stage 2 Flash and S1 Cam, 3rd and 4th are now my favorite gears! Way more punch in the mid-range and getting up to 60 is done with ease and I’m 220 lbs. Don’t waste money on a cheap exhaust; do yourself a favor and buy a reputable brand (Yoshimura RS-9T) and intake and you won’t regret it. To make the Cam install easier, pull off the flywheel, release the pressure from the cam chain tensioner and while in there, replace and upgrade it.
