I have finally finished installing an LS3 into my VY commodore. The question I have is in relation to the knock sensor wiring for the ls3 knock sensors. in the tune tool we get this description.
The PCM can be used with two types of knock sensors, this parameter allows you to select which type of sensor is fitted to the engine.
The standard LS1 sensor is a resonant type, these sensors are connected like so -
Sensor Bank #1 - J1,pin56
Sensor Bank #2 - J1,pin11
If the engine is fitted with flat response sensors (like the LS2 uses), then the connections are like so -
Sensor Bank #1 GND - J1,pin49
Sensor Bank #1 Signal - J1,pin09
Sensor Bank #2 GND - J1,pin50
Sensor Bank #1 Signal - J1,pin10
Only the following values may be entered into this table:
- Resonant (LS1)
- Flat Response (LS2)
Are the two grounds already wired from J1 pin 49 & 50 or do we need to add these wires ? Is J1 the red or blue connector?
Thanks in advance Mick
