How to improve knock detection?

[knockretard]

Hello, I have setup knock shield using https://github.com/Bylund/Knock-Shield- ... xample.ino

It was easy to do because your manual is very good.

Only thing I changed to suit my engine was the Setting band pass frequency

I have a V8 with 102.3mm diameter pistons so I used this calculator: https://phormula.com/knock-frequency-calculator/ to get a frequency of 5.6khz

According to the Technical Manual (http://www.bylund-automotive.com/educat ... Shield.pdf)

the closest value is: 5.68 kHz 0x24 0b00100100

Here is a sample of my log. I am using 2 knock sensors Bosch KS4-P. I just did some light driving. I have conservative timing and high octane fuel.
Question 1: Does this look correct? I'm a little surprised that results aren't consistent between both sensors. On this V8 they are mounted on the outside of the iron block, one on each side of the v8.
Question 2: how do I know whether I should adjust the gain or KNOCK_THRESHOLD_LEVEL?

Hello!

It was easy to do because your manual is very good.

Thank you, it seems you have understood it very good!

Question 1: Does this look correct? I'm a little surprised that results aren't consistent between both sensors. On this V8 they are mounted on the outside of the iron block, one on each side of the v8.

I agree with you, it looks a bit asymmetric. Have you tried swapping the sensors to see if it follows the sensor or if it is the actual reading? Make sure the sensor is mounted on a good plane and clean surface.

Referencing the datasheet of the sensor.

Question 2: how do I know whether I should adjust the gain or KNOCK_THRESHOLD_LEVEL?

If you reach the KNOCK_THRESHOLD_LEVEL without the engine knocking I would reduce the gain. Often you want to know what is your safe level that you do not want to pass. Note, that you are a bit limited without engine speed.

There are plenty of videos discussion threshold levels, here is one example at 5:00.

Hope it helps.

Hi knockretard,
Just wanted to also raise the topic of mounting torque.
I assume you are aware of this anyway, but i wanted to add this for other readers of your post.
Make sure that both sensors are torqued to the recommended spec of 20 + or - 5 Nm.
Also try to use bolts or studs made from the same metal properties, EG: Don't use one 316 grade stainless bolt and a mild steel bolt on the other sensor.
Regards
Dave.

@knockretard - how did you time the readings between channel 1 and 2? Is it just fixed timing and alternating? I plan to use an interrupt based on ignition spark (understood crank position would be better), my concern is that if I alternate between channel 1 and channel 2 per ignition spark, I will be missing knocks between the two. I have seen the same question asked in other forums regarding the TPIC8101 chip, but no answers.
