DHM Performance ECU Flash for the 2022+ Honda Grom / Monkey / Dax

2026 Hinda Monkey ECU

I already had installed exhust and intake and when I added the tunned ECU it really complimented my mods and the bike is running great! I gained a few mph and take off is much better. I would recommend this mod for sure

Woke the Grom up

Tune worked great. Butt dyno its hard to tell it increased power since they dont make that much but confirmed racing against my girlfriends grom it took the weight advantage she has over me away. Got up to 60mph quicker previously sticking around 55-57 in 5th. 200lb rider. Smoothed out the throttle response and the acceleration. So happy I got my girlfriends tuned. Now she is back to winning races. Overall same results on hers. Highly recommend to do it if you mod the bike. 22/23 grom with intake and exhausts.

My monkey run much better

It change my bike , I just put a Takegawa muffler and my Monkey was running lean. My bike have more torque, I gained about 5 mph top speed. The bike can rev more and the gain in power for the 4th and 5th gear are nice. I recommend DHM écu Very good services from DHM
