XH + knock sensor

For a few reasons I havn't been able to reconnect the knock sensor to my XH, yet I've been driving around for a few thousand kays without it. I'm just wondering what, if any difference it makes to an XH with the ED style intake.

In an effort to squeeze as much out of my new engine as possible I've been advancing the timing again and again expecting it to ping, but nothing. Its around 15-20 deg advanced at the moment so either the marking on the balancer is wrong, or the lack of a knock sensor is preventing it from advancing as much as I've manually moved it or something different again.

[EDIT: Doesn't throw any computer codes either.]

Is there anyone out there with an auto series 1 XH willing to disconnect the plug from their knock sensor while they take it for a spin and tell me if it made any difference?

Any help appreciated!

Re: XH + knock sensor

If the computer is similar to an EF one, it should spit an error code of 227 for an open knock sensor circuit.

Another idea would be bridge the knock sensor circuit without the knock sensor and see if the timing responds to it.

Re: XH + knock sensor

Yeah, I would have thought it would throw the 227 code myself. But this is why I asked the question, as I 'think' the knock sensor does nothing on XH's.

Dont know about bridging the circuit though, dont want to start any fires...

Re: XH + knock sensor

My knock sensor works.
If I advance the timing too far and quickly open the throttle, it will detonate for a brief second and retard itself.

It worked with the old manifold and the BBM.

Re: XH + knock sensor

I've got an EL ecu in my EB, and without a knock sensor connected it did not throw a code for it.
I have got an AU knock sensor installed with the EL ecu, and dont know if its working 100% as it still pings occasionally, but I am running heaps of timing.
There is still no code being displayed for knock sensor.

Re: XH + knock sensor

15-20 deg base timing is still ok, im running 20 in my eb.. and it dont ping.

with the knock sensor disconnected you can run as much timing as you want, you see the way the knock sensor works is it creates a voltage when vibrated at a certain freq (pinging) and so the computer registers the voltage input, with it disconnected your computer will just never see any voltage input and think things are all ok... due to the way it works, there is no way of bridging it.
