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.

By controlling the air/fuel ratio we're able to extract up to 3HP more in the higher RPMs.

It runs extremely lean up top and therefore only makes around 6-7HP at 9200rpm. Looking at the dyno graph, you'll see the blue and green lines that are the graphs for the stock, unmodified ECU. **Mail-in ECU turnaround time is only 1-2 business days!ĭHM 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 on bikes with intake and exhaust modifications.
