89 MJ Posted November 29, 2020 Share Posted November 29, 2020 My 96 Block that is going in my 89 does not have threads for the knock sensor. Is the knock sensor truly needed, or can the computer be tricked and not needed? Link to comment Share on other sites More sharing options...

SVPete Posted November 30, 2020 Share Posted November 30, 2020 My read of the renix fuel injection manual would lead me to believe that you could leave it disconnected. If a knock generates an electrical signal which would then cause the ECU to retard timing for 15-ish seconds, then return it to normal.... If it's not connected, then it can't send a signal to retard the timing...right? Maybe some smarter guys will confirm or shoot me down. Link to comment Share on other sites More sharing options...
