Knock Link, knocking sensor
 

Okay, I am a little uncomfortable about my Mugen ECU being run on stock (98RON) fuel in the UK. Now to confirm the engine is not banging away (knocking) I was thinking of installing the Knock Link sensor. Anyone got experience of these units on the S and have you used the stock knock sensor connected to this or a separate unit bolted to the manifold. IS the stock knocking sensor a Bosche unit?

Thanks, Lee.

IMO you are OK as is, especially if you don't hear anything, but if you are really that uncomfortable I suggest you go back to the stock ECU rather than trying to pioneer a fix without a way to test it.
