Alan Posted July 19, 2017 Report Share Posted July 19, 2017 Hello,I have a G4 Plug-In (G4 Topboard Extreme, Firmware 4.10.2) for my 2003 MINI Cooper S, and I am setting up Knock Control.The diagram in PCLink Help labels Pin 8 as Knock 1, and it is the pin where the MINI Knock Sensor terminates. But when setting up Knock Control the only option is ON - DI Knk Interface. Is selecting ON - DI Knk Interface all I have to do?

Simon Posted July 19, 2017 Report Share Posted July 19, 2017 Hi AlanOn the G4 to get knock control you need an external Knock block to interface with the ECU. It did not support internal knock.Unfortunately the Knock block (G4) is no longer available. Quote Link to comment Share on other sites More sharing options...
Alan Posted July 19, 2017 Author Report Share Posted July 19, 2017 Well, this thing is worthless to me then. Does the new MINI plug in support knock? Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 20, 2017 Report Share Posted July 20, 2017 Does the new MINI plug in support knock?The G4+ Mini Plugin does have built in knock hardware and it is connected to the stock knocksensor/wiring. Alan 1 Quote Link to comment Share on other sites More sharing options...
Simon Posted July 20, 2017 Report Share Posted July 20, 2017 Hi AlanIt is important to remember the knock is a protection feature in an ideal situation I would hope you will never see knock and as such the feature would not be put to use.Back in the day this was a feature held back from the Link units but was enabled in the (premium) Vi-pec units.

Alan Posted July 21, 2017 Author Report Share Posted July 21, 2017 For a street car I would agree with you, but this ECU is for a race motor that will spend over 50% of its life at WOT.Knock Control is the final line of defense against race conditions not anticipated in the various trims, or variations in fuel.
