DHM Reflash and TB Cam Package (Stage 2)
***If you already own a DCR or TB camshaft you can still purchase our Reflash for those mods here: https://www.dhmotoring.com/products/stage1reflash
****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 TB 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)
Included:
DHM Reflash (more info here)
TB Parts Camshaft
***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.
Cam Installation:
I ordered the DHM reflash with a tbolt cam. Ran okay for a little bit, but didn't last long before I started realizing all these issues. After resetting the ECU, (which I had done a couple times already before) it seemed like the flash went bad or my ECU went bad. Bike has under a thousand miles on it and ran perfectly fine before. I reached out to DHM with my concerns and they stopped responding... Recently just bought a new STOCK ecu and gonna put the STOCK cam back in and see if the problems continue. Right now with the DHM re-flash my bike acts like its in a limp mode with rpms jumping up and down at all throttle positions and its not ride able. If DHM would like to write back to me, i'd love to figure it out and keep the cam in there.. but this whole thing has been sorta a pain in the a**. every stock grom i've had has been bulletproof. The cam and flash was science so everyone knows its not a good idea.
First off, the service was fantastic, with fast shipping.
I own a 2014 Grom with 13000 km that I had since new.
The power gain for the price is awesome, I also bought the stock air box, Koso tube with adapter. Both were easy to install, and the performance is huge. I can now cruise at 100km/h VS my old 90km/h, not to mention gaining speed going up some of the hills I travel. The engines low rpm torque is gone, and shows up in the higher engine revs 7000 rpm and up.
I am very happy with my purchase and the performance gains.
I have been buying from DHMotoring for about 4 years now. Every single part is currently still in use and going strong. I am just here to buy more parts and continue the upgrade.
Haven’t had a single issue, and I mean the slightest. Installation and instructions are really clear, and endless YT installation guides. I love this company. They turned my baby grommie into a speedy little demon.
I have been in touch with the owner and he has been responsive each day with questions regarding The Ecu I purchased. Unfortunately my bike worsened and have asked to have this ECU returned. Please don’t be discouraged buyers from buying his product. However, I had a bad experience and was a bit of a waste of my investment. I am keeping the tb cam as it has helped me. At this point I have asked for a process for return and have not received instructions on what to do for the returning process.
Cheap easy hp simple install fast shipping and excellent customer service answered all of my questions monkey is a lot more fun to ride now revs out and pulls a lot harder in the upper rpms
