Knock Sensors

[Mushroom]

hey Guys,

I have started cleaning up the wiring on my car and found the knock sensors weren't even hooked up. Now my car runs a Haltech ecu but i still would of thought it would need these to run, can anyone shed some light on this for me (esp where the sensor wire plud is suppose to connect to)

Look down the back of the engine on the drivers side close to the inlet runners.

And on further searching have found that they do not incorporate closed loop knock sensor control.

Future reference....www.google.com.au

Type - Does Haltech use knock sensors

Google is your friend.

OK so should i worry that it doesn't detect knock?

Well maybe....

In the end if the tune is safe, you use good fuel all the time, your injectors are clean, your fuel pump is in good condition etc etc.

With skylines a standard ECU is the only computer that uses the knock sensor as input, it moves to a "safe" map when it detects knock.

PFC comes up with a knock "number" based on the sensor but does not use it in the tune. If it is knocking its up to the driver to back off.

AFAIK no other aftermarket computer uses an rb knock sensor

ok thanks I have seen a hks model that detects it but well i really don't drive my cars too hard (I spend too much time cleaning and looking after them to want to hurt them)

The Link ECU has a system where if the knock is too high, it will reduce the boost level until the knock is reduced. The Link ECU uses the factory boost controller to control boost up to 14psi.. COuld be more, not sure though.

bit of a question on this one...

assuming i'm using a stock ECU, is there any way to monitor knock?

I've got one of the Nissan Datascan units that Impakt (off these forums) makes that gives a readout of all the ECU parameters... the only one that it doesn't give that could be helpful is the knock readout....

any ideas?

ok I have found turboXS make a knock light and shift light all in one ($180 approx) (look in the current autosalon mag) Unfortunatly every supplier for turboxs I have tried haven't even heard about them let alone stock them
