Yup, I ordered that and the GM Knock Sensor Conversion for Doc to install. Along with the healthy dose of goodies that he's putting in the car.......should be really niiiiiiice.

i woudlnt recomend using the GM knock sensor. it dosnt work correctly for our cars and ats should stop selling it imho. keep the stock sensor.

Just to add to the heated fun here.

I had a stock Toyota knock sensor on my All-trac with a Link Plus EMS. The EMS let me see the knock counts in nice pretty graphs, and under heavy boost I was seeing a ton of knock - tuning was in order.

Anyways, I went through 2 knock sensors in as many months, then I switched over to the GM knock sensor. Same knock counts, but the sensor held up. A couple months later and the motor crank-walked due to bad machining. Regardless, the GM sensor had worked fine.

So, I recently installed the GM knock sensor on the 3rd gen powered 6GC, and I started getting code 52 on the stock 205 ECU. Switched back to a stock knock sensor and it cleared up. Checked the EPC and the part numbers for the 3rd gen 3S is different then the 2nd gen.
