Up in the air..

I installed the CAM and the ECU on Friday and took it for a quick ride (5 miles or so) and I’m not sure if the ECU still need to learn the bike but 1st gear kinda putters a bit on take off. And, I looked pretty much everywhere but there was no real info on what the valves should be adjusted to.. However, apart from the 1st gear thing: it definitely feels a bit snappier..

Quality

Motor actually feels alive above 6500k. Definitely recommend if you're looking for a pump in power up top! Nice piece, took me an hour and a half to install. Motor has a nice bark to it now too!

Simply amazing!

By far the best upgrade I have done for my Grom! My bike always seemed to struggle and had power dips before this. Now I have better throttle response, more power through all gears, and the bike feels and sounds better. My bike struggled to stay at 55 mph on the highway before and now I can hold 60 mph easily even going slightly uphill. Currently have Chimera Intake, Yoshi RS-9T exhaust, and S1 Cam shaft. About to put a 14T sprocket in to improve it more. Thanks DHM!

Stage 2 Flash & S1 Cam Package 2022 Grom

I can't speak for the tune as of yet but the cam is a good quality part and the customer service is great! There seems to have been an issue with the tune so I sent my ECU back in.
Hopefully all is good when it comes back!
10/10 would do business with DHM again.
Thanks yall.

Great upgrade

Bought the dhm stage 2 flash with cam package and it is definitely worth it. I’m running the kit with the mnnthbx intake and its definitely is quicker than before. Starts right up and has zero issues. I sent my ecu in for the revision, and it was shipped back to me in less than a week. I’d recommend anyone contemplating this to just go ahead and order it!

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


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.
