Installing the EHS Tuner on my 2021 Yamaha Grizzly 700.
The EHS Tuner is a Fuel Programmer. it Plugs into your injector harness and stays plugged in, You can adjust your fuel curve on the ride. Highly recommended , Helps with cold starts alot.
Not very hard to do, takes about 40 mins if your taking your time.
If you have basic mechanical skill youll be just fine

Ill make a video soon on what i think of it, but i can say already its quite the difference
