Lets talk knock!

[compactfean]

So in my quest to monitor knock so I cam safely turn my boost up to high levels I've found a road block. I there any software that monitors knock through the consult? I would like to see what my oem ecu sees before I trust my e-manage ultimate. Also anyone with experience on the emu and the hz settings please chime in.

Anyone?!

Nein.

Doesn't the knock sensor detect it? I don't think there is anything to detect detonation BEFORE it happens, if that's what your asking.

No, I know the knock sensor does its
Job but I need to be able to monitor knock so if my boost is to high causing knock, I can turn it down to a level that won't cause issues. I am trying to tune so it doesn't detonate at all instead of the ecu retarding the timing after it had detonated. It seams that all the write ups I've found us how to get rid of the knock sensor code, but not actually utalize the sensor as a tool (even though the stock ecu does) programs like, conzult I would think should monitor knock but if you have to adjust the hz level than its not much different then my emu. I guess I would be ok monitoring knock from the emu if I knew what hz level to set it at, and if I knew for a fact it was working, that's why I want to see what the stock ecu sees and compare to make sure my emu, is working properly.

Mods please move this to the NOM section. I'm not getting any answers here.

Compact I looked into utilizing the knock sensor when I change to megasquirt. long story short I found that most older cars ecu's dont read the knock sensor when the engine is operating above 4000rpms due to the fact that the ecu processor doesn't have the power to read the sensor at that speed, so it just holds on to the last known state. This may be why you cannot find stock ecu software to monitor knock. In the end I decided that the best route was to go with a product called KnocksenseMS from www.viatrack.ca . It is supposed to work quite well and can be integrated with oem and aftermarket ecus.

Hmmm, ok. Maybe thats why I can with my emu. My only concern us the hz settings (don't know much about it) and if the emu is even monitoring anything.,(during data logging it doesn't move) maybe I'm just more seeing any knock and that's why it doesn't move. Idk. I kinda like the idea of the led notification but I trend to tune out gauges when racing. You know of any company that has like a headphone setup? I think I could have quiker response to something audible. People say you can hear detonation with the ear but I have yet to hear anything abnormal.
