Knock count reading, but not connected

[brett_32i]

hi,
another ghost reading!

my ecu doesn't have a knock board as it isn't turbo (but it thinks it is)
i am getting erroneous readings for knock count.
can i disable it in nistune?

[Matt]

You have a VL turbo ROM image loaded into the Nistune board (for an RB30ET/E+T application)

There is no way to disable the input because Nistune does not know if the board is installed in a proper VLT ECU (with knock board) or not. Would just suggest ignoring the knock count from the ECU

[brett_32i]

so i just ignore it?
or set the ecu to ignore it?

[Matt]

Would suggest just ignore it. The ECU responds to a knock count query from Nistune. I could offer an option not to gather the knock count perhaps

wish it was as simple as grounding a pin on the knock board connector.

[Matt]

It probably might be. I would have to work out what each pin does again. One is used for resistance measuring (DTC knock fault code) and another passes the pulse through

[brett_32i]

ok, so although the ecu is reading something, nothing is actually being done with the input. ill just ignore it then.

[Matt]

Thats correct with these older ECUs knock count does not pull timing due to the fault code
