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)
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.
Shipping was fast and everything fit like it should . I have only driven it about 40 miles and it was pretty windy so I'm not sure how much difference it has made but I think it did help some . I need to race my buddy that has a bone stock grom to see how it does .

Cam install
This has made my 25 grom a completely new bike I dont know if it was just the cam and tune or because I only had an exhaust on it prior but it is a huge improvement. Everything was simple and fast. Shipping was within a week counting my shipping for the ECU. Would definitely buy again.

Excellent
Service and parts, excellent all around! My grom sounds badass and feels so beefy now with my stage 2 upgrade. Worth every penny and this is the place to get your parts and flash your ECU.

Noticeable improvement
I feel like this was worth the cost. It was pretty straightforward installation wise. The bike started right up and ran well. From the first ride I could tell there was a little more there. The rev limit bump is nice as well.
Buy it

I installed the DHM S1 cam/ECU package. Came fast and works as advertised. Great kit and easy to install. The power increase is noticeable. Don’t even think about doing it, just buy it. 1000% worth it.
