Hey Guys,

I am looking at my options in purchasing some form of audio knock detection and have come across Tuner nerd Knock monitor pro software and hardware.

http://tunernerd.com/

It looks like a relatively basic programme that records the audio from the knock sensor and the applies a hi and lo pass filter and also has a dynamic threshhold which i like.

At $300 it is affordable for me.

Does anyone have any experience with this??

Any help appreciated.

Thanks

Kenian.

I´m also interested in this device, is there nobody who tested it and can share his experiences?

I have used it alot and i love it. But im one of the main testers of the software/hardware so i might be biased.

There is another thread on here somewhere that i responded to recently.

Which package would you recommend?

Depends what you want out of it. If you want to log a file with RPM, MAP and AFR data then the pro is for you. If you just want to listen to the engine, make a recording of a run and be able to listen to your run(s) again (as well as a visual representation of it all obviously), then you could be ok with the "light" verson.

was just thinking if the wireless headphone makes sense

Did anyone end up getting this? I'm thinking of buying a kit also

Hi there!

I just got this in. Tonite we are setting this up on a car and map the car on Sunday. I will report back ASAP with my experience.

Edit: i got the pro version with the million wires :)

Kind regards,

Vincent

Thanks Vincent, I just ordered one anyway so I guess we will both find out very shortly. Let me know how you go

will do!

Hi there!

Finally sound some time to come back the the forum.

We tested the knock monitor last week. We set this up connecting only the rpm probes, 1 knock sensor and attached the ground from the engine block to the single black probe. We got the rpm coming in strong. We did found that the wiring was quite extensive. Taking 2 usb ports on my laptop: one for the data feed and one for the external sound card.

I have sound that the software was quite buggy. It did freeze/crash quite a lot of times. Also the audio coming in on the wireless head set was hard to dial in to to acceptable knock detecting volume. I assume that i am doing something wrong there. But after some hours we gave up on the audio.

The visual of the knock detection was quite nice and straight forward in configuring. It did gave me some insight on what was going on but without the audio coming in strong i was still not confident enough to continue this way.

With that said i connected my knockblock to a second knock sensor and used that audio.

I would love to hear other people's experience about this product and love to learn.

Kind regards,

Vincent

Same experiences for me. Feels little buggy and takes time to get settings right, also quite poor instructions. When adjusting laptops master volume, it messes up the program too. I tried to get map too, but car became running very lean and stalls etc :o When I take blue probe out of map sensor connector, it cames back to normal :o

Guys

Get a proper tool.

PlexV2

Tuner nerd simply perfect ! Last week recived mine i was impressed how accurate detecting even light knock ! For increase the sound should go to audio settings . For me working good comparing to phormula pro

Price is very salty for Plex V2, for a guys who want to just learn to tune their own car :(

I just picked this up with a buddy. I'm sort of disappointed to hear about the wireless headphones being hard to dial in. I'm hoping that's a setting and not actually the case, it was kind of the whole point of getting this system.

I haven’t got mine yet but I did speak extensively with the support team before I purchased. He was very helpful. Those of you that are having issues with it, did you contact support?

Any updates or reviews on this? I canceled my order with tunernerd and I'm debating going with a link G4+ knockblock for now.

I have the Pro version and am encountering some issues with the bundle. Having said that, the support team is working with me to solve the issues I am facing. We'll see how it goes. Oh, the knock sensor look pretty much like Chinese copy.

The bugs described here have since been sorted out.

-The 5V output now fixed, works all the time now

-The random freezing while knock detected now fixed,

-The headphone Bluetooth is optional, you can still connect direct to wire. We found the Bluetooth to have a small delay.

-The knock sensor in version 2 is the Nissan version that is internally grounded. Used with the unit there is no problems but if you should attempt to rewire polarity will be a problem. Tried a Bosch, not much different, just overall quieter - but the Bosch are usually not internally grounded.

Version 3 only carries the genuine bosch units.

-Map sensor be sure to ground the knock monitor at the ground of the sensor and not on the car body. There is a potential difference (voltage) between sensor ground and chassis ground.

I purchased the Tuner Nerd Knock Monitor Pro but can't get it set up properly. I am getting the RPM signal from injector 1, and also installed the knock sensor. I could not put it in the exact same place as the OE knock sensor because the bolt hole was too big, so I found another place which is quite close to where the OE one was. I did not manage to get the MAP signal because I couldn't find the multiplier and offset numbers of the MAP sensor. I have a Toyota 4efte and most sensors are the OE ones. I was told that I do not need to use the black wire (ground), and my AFR is wired to the ECU.

My problem is that as soon as I connect to the software and I start recording I get a lot of knock at idle. I tried retarding ignition just to make sure it wasn't the case but I still kept getting the same signal. I obviously have something which isn't in place so I haven't been able to set the right threshold. STUCK!! :/ and I really need to get this working because I need to tune ignition (road tuning - so this is my only hope of getting it right)!

In order to get a rather decent signal I have to decrease the Gain and the Frequency, but I was guessing that it beats the purpose.

That's because you set the threshold, then adjusted the gain/frequency afterwards.

if you adjusted any of the knobs the threshold is now invalid and you must do a new threshold.

Also, any spikes you get at idle is sound from ignition or injector solenoids. Ignore anything under 2000 RPM

Also, you may disable the threshold and work in auto threshold mode, that way it detects knock on the fly without you setting a threshold. :-)
