Anyone using one of these? I'm trying to install one on my CGT, the problem is it didn't come with a knock sensor and I'm not sure how to retrofit a Bosch sensor to the system. My email to J&S has thus far gone unanswered. Dwight Varnes 86 CGT, 2.3 swap now actually in the car! Schrick, Addco, Boge, Magnaflow, Momo, Yokohama, Team Dynamics and much more.
