Great product, a must if doing any upgrades to your Grom. I have had 2 ECU tunes done by them and each time very fast turnaround time. Very fast and informative support from them as well.

Proven flash from DHM
I’ve flashed 2 ecu’s from DHM. A 22’ Grom and 19’ Monkey. Both ran great with the flash from DHM. Definite power increase with a cam/intake/exhaust set up. The best part is the turn-around time. The Ecu’s were pretty much shipped the same day they received them.
