***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.
****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)
***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.
This cam with a chimera Intake and yoshi RS-2 wakes the bike up past 6k RPM, very capable at keeping up with traffic at 55MPH plus, well worth the money, as someone who’s not very mechanically inclined, this install took me an hour, just take your time and follow the video step by step

Great upgrade
Install took less than an hour its very easy and it made a great improvement of power, i have a -1 front sprocket on my grom and my speedo read 79 while hitting limiter on the highway. The extra rpms are great, only thing is i have to rev it a bit on cold start to get it to hold an idle but i can probably just turn my idle up

Dhm stage 2 cam and ecu
I will definitely be doing more business and recommending to friends in the future. Placed my order online and sent off my ecu on a monday and had the cam and ecu back by friday and im in NY. Install is super easy if you are mechanically inclined. Cam and ecu woke the bike up drastically. Interested in the 186bbk in the future.

Cam n Tune
Was a little disappointed at first it was missing the spec sheet and slowed down the install process but emailed them and got everything needed to get this installed. Now just need to wait on weather to warm up some.
All in all. I am happy with product and thier customer service.
