DHM is here to offer you the original flash tuning solution for the Honda Grom / Monkey! Our stage 1 software cleans up the air/fuel ratio and optimizes ignition timing among many other tables for bikes with nearly any modifications. We have tuned over 10,000 ECUs to date and are the premier tuner for the Honda Grom and Monkey.
Looking at the dyno graph, you'll see the blue and green lines that are the graphs for the stock, unmodified ECU. It runs extremely lean up top and therefore only makes around 6-7HP at 9200rpm. By controlling the air/fuel ratio we're able to extract up to 3HP more in the higher RPMs. The peak number is only about 1hp but in a race on the street the tuned bike will continue to pull gear after gear because it does not lose power after 7,000rpm.
Our ECU flash not only increases horsepower, but it also makes the engine run safer now that it has adequate fueling.
***This is the best alternative to a fuel controller, especially at the price point. You no longer need to spend hundreds of dollars on a tuner if you only have simple bolt-ons on your bike. If your bike is running a modified intake and exhaust this is your ticket to a smooth running bike with OEM like ride-ability. Since we retain the stock ECU, the bike will start, run and idle like normal, but will produce more and safer power throughout the rev range.
***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.
We have maps for pretty much every intake, exhaust and cam that is available on the market.
