Looking at getting an afr. What's everyone using and how do they like it?
 
I'm getting the afr+
Search afr+
Comes with everything you need plus it's programmable . The guy that invented this also invented dynojet.

Doc uses a ballenger digital bright red gauge and bought his own wide band O2.
 
Ok, typically how long do the sensors last?
 
I have the auto tune with the o2 sensor and I have about 3000 miles on it and i am going to replace the sensor this year just due to the fact that It will not read anything when I start it and other times it works and reads perfect I started have this issue at about 1800 Miles
