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

$329.00
ECU Core

If your 2022 Grom/Monkey 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 $75 credit or keep it as a back up.

Incredible

The cam and the ECU were packaged accordingly and both went in smooth. The increase in power gives a bigger push and makes the bike much more usable in higher speeds at 100kmh. This will give any rider a broader use case for the Grom, letting me get to the speed I want without having to tuck and pray. I've been kindly advised to go on 95RON and my fuel consumption had a minor increase, which was to be expected. With stock gearing I get a little front wheel lift when changing gears on full blast up to 10k rpm. Well done, hats off to DHM for making my daily commute a hell of a lot better! Incredibly happy with how much this enables the bike!

Non stop smiles

After installing the cam and flashed ecu, my butt dyno wasn’t sure of any changes, but when I went riding with a friend with the same bike and same weight with only intake and exhaust, I was taking hills and breezing past him with a huge grin, where we used to be neck and neck every time. Huge smiles now when riding. Thanks!
