OnegreatGuy Posted February 16 Report Share Posted February 16 Hello all, I would like to set up knock control with my MR2. I've been advised that the OEM knock sensor is close to garbage, and that I'd be better off switching to a flat response knock sensor, specifically a Bosch one. I'm curious if the mr2 PNP ecu is compatible with one of these sensors, and then what specific Bosch sensor I should get. The OEM knock sensor has a thread of M12x1.5, and a mounting surface of approximately 24mm in diameter. Thanks in advance! Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 16 Report Share Posted February 16 0 261 231 188 is common and cheap in most regions. You can get a M8 stepped stud from Toyota that screws into the M12 hole and allows a knock sensor with an 8mm hole, 90126-08039 or 90126-08046.

koracing Posted February 20 Report Share Posted February 20 I've tuned many turbo MR2s with the stock knock sensor just fine, or the common GM replacement sensor. Quote Link to comment Share on other sites More sharing options...
