Hi I got a sierra saphire with Autronic ecu running 525bhp and as I had some trouble with detonation and who tuned the car didn't use any knock control, I wanted to know if I could install a knock sensor compatabile with the Autronic ECU to control the knock on the engine as I am thinking that the car is too advanced and cousing the piston to melt even if I am using Sunoco Racing fuel all the time 109ron.

I would like to buy a knock sensor to install with the Autronic SM4 ECU


Thank you for the help
