Works well overall, needs securing prperly.
I have tested this sensor holder/clamp on a few cars now and I can testify that it does indeed give good results. It gives somewhat erratic readings at idle but at 1500 rpm and above it gives the same readings as the sensor in the front pipe. It does have to be secured properly though, the little thumb screw is not enough and will mark the exhaust tip. I used ducting tape. It has proved very useful on multiple cars for quick set ups and readings. Overall recommended.

I use this tool for road tuning pretty often. Apart from the reviews saying to tape it to the exhaust (which I have done) it’s a solid purchase! Great for tuning on the road, and on the dyno. Highly recommend!!
