Replacing Knock Sensor With Resistor

[Rolls]

Can anyone let me know which ECU pins the knock sensors for an RB20Det R32 ECU are and what ohm resistor I need to bridge them out? I have been getting timing pulled randomly for no reason when cold, it has only started happening with the winter ending and no actual audible knock, which I highly doubt as the car is running slightly rich and retarded already and I barely put my boot into it when cold.

I have already added most of the timing back to the cold start maps, it is fine when I start the car stone cold, then about 2 mins into the drive it will pull a lot of timing down low (probably a different issue) but also then across the upper rev range as well it feels like it is running on the knock maps (I have 3 degrees less on the entire map here)

Do not have a nistune license otherwise I would just nuke the knock maps.

Thank you.

edit: apparently I require a 500 ohm resistor, can anyone confirm? I guess I could just put a multi meter on the sensor to test.

500kOhm. 470k may be close enough, otherwise you can always series up a ~30k with it. Or parallel 2 x 1MOhm resistors.

The 2 knock sensors are on pins 23 and 24.

Importance on the KilOhm so 470,000 ohm resistor attatched to the wire that the knock sensor would be on, and then just run it to earth.

Ok just replaced, time will tell tomorrow if it helped.
