Do you have LPG?

You can even use an amp like this

I use a cheap version of these. Better to isolate outside noise.

Okay. I buy the first. Thanks for ur help

Try looking on ebay.co.uk for instrumentation,it is less expensive.
Tony has done some tests with various probes, also ask him.
Good night :)

I've found this simple guide to build headphone for listening knocks, if it could be usefull:
Knock Listen Device.pdf


If we don't use the same knock sensor also for the ECU, is it possible to don't use the capacitors to isolate the signal?

So, I think that we could use some classic rubber headset with this above to spend little:

He should not connect it to the ECU but only hear him. He does not need an interface module.
For the headphones i use working headphones with speaker inside.
I used the image as an example.
I prefer big speakers rather than small earbuds.

Yes, he don't need with MS2 to connect the knock sensor to the ECU but that guide could be useful to make a simple and clean connection.
For the headphones your solution is the best, mine is another cheaper one.

I'm fine thanks.
I don't understand why you want to use the t-jet pistons.
They are for a motor 16v and then you have the flare points (those for the valves) where it could remain unburned gasoline.
Why not use the stock?
The t-jet pistons hold much but you do not absolutely have to have detonation.

provisionally you can make a map without EGT, but you'd better be very careful with the map
