I recently bought an '07 Rocket III which has a Jardine exhaust. Not being familiar with these, I was looking for where the O2 sensor is and can't find one. I see a port that has a plug in it but can't find the sensor. What gives? Am I blind or??? Thanks for any help.

Sounds like that plug you see is where the O2 sensor would go, if it were there. Someone probably "deleted" the sensor, hopefully using TuneECU to tell the puter that it ain't there. I have one Rocket without the sensor, and 2 with. I think the sensor helps the computer keep tabs on the engines running condition.-

That must be the case. Not being super familiar with fuel injection, I thought an oxygen sensor was necessary, but I guess not. If it runs OK, would you recommend leaving things alone, or should I pursue installing one and enabling it with TuneECU?
