Dude just follow the instructions...
"LOOSEN ACCEL ERATOR PEDEL AND CLCIK OK"
That's so bad lol. I've heard their customer service sucks, too. Knock on wood though, the product has worked perfectly for me. I'd love to go with a real company like Banks, but they haven't made one for it yet. Hopefully they will soon. Roar Pedal is just some guy in Maryland buying overseas chips and selling them. Their "address" is literally an apartment IIRC lol.
I didn't do the learn function, I don't feel it's necessary.
@Mikey Swift will yell at you if you don't, though
