Hereīs a pic, what the controller looks like.
It is available in Germany for about 200$ and is P&P. It ifluences the stock O2 signal in the area (first 1/3 to 1/2 of rpm range) where the emissions are monitored, so the bike wonīt run too lean anymore.
=better AFR, better throttle response...
with the 2 twist buttons on, u can adjust the controller to your personal style of riding (how can this work well??)
I donīt know if itīs worth the money to pay for. No one who has ever ridden it???
