So I just got my Auto tuner for my 2009 CBR 1000RR with my Yosh R77 slip on. Well one thing Dyno Jet does not do is put there install instructions on there website. And for good reason. If they did, no one would buy it. Why would you use a full size O2 sensor for a sport bike. The dam thing will fit in my truck. So I have to drill a hole in my brand new exhaust and weld the plug in even though the R77 has an O2 plug for a motorcycle already in it. But like I said Dyno jet uses a O2 sensor that can be used in a car. Then on top of it this in no way is a simple plug and go item. You need to crimp wires, find ground locations and all sorts of other crap.

The directions are no help what so ever. For example.

"Connect the O2 sensor cable to the O2 sensor and route the cable to the Auto Tune module ensuring the cable will no get pinched or damaged by the exhaust. The cable can be trimmed shorter if desired."

What friggen cable are yu guys talking about. The dam kit came with four cables!

Whatever. Super pissed right now.

This is how big the O2 sensor is.

 

send that thing back to much trouble than its worth dont need it anyways

 

Shouldn't matter. So long as it's a coaxial (two leads) cable, any will work. Maybe figure out what the other 3 cables are for, and that will give you your answer?

 

i know my 929 has a full size o2 sensor like my integra would use. so youre saying that the yoshi exhust has an o2 port that is smaller then the o2 senor provided with the dynojet kit ?
