Product Description

Meet the new PLEX KNOCK MONITOR v2.0
The quintessential tool for tuners, now with dual knock inputs.

Keeping the same ergonomic design with the renowned Plex Knock Monitor (version 1.0), we fully reconfigured the hardware in order to offer an even better knock detection device that addresses the growing needs of tuners and engine builders alike.

We added a 0-5V analog load sensor input to be used for MAP or TPS, increased its rpm range up to 18,000, optimised its audio clarity and now provide it also in a dual-knock input version, the right choice for twin bank engines.

The World’s Best Knock Detection Device is now available for ordering.

Tune like a pro and never miss knock again.

Best-in-Class Audio Quality NEW!

Improved signal-to-noise ratio (S/N)
by 20dB raises the audio clarity big time
and reduces the total noise 10 fold

Transflective Display NEW!

New 2.3’’ transflective LCD display offers better
viewing in daylight and outdoor conditions thus
enabling knock detection on the device without
a PC being always necessary

KNOCK MONITOR v2 AUDIO-MIX LOW-RES

Dual Knock Sensors Inputs NEW!

Optional dual-knock sensor input with increased
dynamic range, suitable for twin bank engines or
for enhanced knock detection. Choose whether to
split the audio channels per sensor or listen to them
combined.

0-5V Analog Load
Sensor Input NEW!

Connect a MAP or TPS sensor and
perform 3-dimensional knock data
on the device or PC

Non-volatile Device
Logging Memory NEW!

Capture 3-dimensional knock information and
log knock count with knock level per cylinder
versus RPM and load

Dual Audio Output Sockets NEW!

Benefit from the two audio output sockets by
using them either for training your apprentices
or for cross-checking the knock signal
with colleagues

Higher-Performance
Processor NEW!

New higher performance main processor improves
the calculating speed making the monitor faster and
smother in operation

Dual Power Options NEW!

Now you can power up your knock monitor not only
externally but also via its USB port. Detect knock with
higher convenience irrespective of where you are.

Isolated USB Port NEW!

USB port isolation provides electrical protection,
more robust device communications and added
noise immunity

Isolated Trigger Input NEW!

Optically isolated trigger input protects the device
from ignition signal noise & related electrical damage

EASE OF USE AND ON DEVICE CONFIGURATION

3-step Easy Knock Detection

Detect knock easily in just 3-steps via
preconfigured basic presets and on screen
wizard, without the need for a PC

Easy Menu Navigation

Navigate the ribbon menu structure smoothly with
4 dedicated keys that provide tactile feedback and
on screen help

KNOCK MONITOR v2 FREQ vs BORE SIZE CALCULATOR

Build-in Frequency vs
Bore Size Calculator

The on-screen engine bore size reference
lets you select the knock frequency effortlessly
by simply choosing your cylinder bore size

Super Bright LED
Warning Function

Configurable two-level knock intensity
alarm to get your attention in the dyno room.
Never miss knock again

KNOCK MONITOR v2 ADV PRESETS

8 Configurable User Presets

Every car is a unique case. Store your most
common engine settings in 8 different presets.
Retrieve easily in just seconds. Don’t waste time

IGNITION TRIGGER INPUT FOR KNOCK DETECTION PER CYLINDER

Detect knock-per-cylinder without the need for additional knock sensors
(up to 8 cylinders)

Individual cylinder filling and temperature are never exactly the balanced. Without using per-cylinder knock detection and as one has to tune for the worst performing cylinder, the resulted engine performance is below optimal.

With the Plex Knock Monitor you can maximize performance of each cylinder individually, utilizing the engine’s maximum potential. Reliability and accuracy at your fingertips.

ADVANCED FUNCTIONALITY FOR HIGH-END TUNING

Knock Threshold vs
RPM Setting

Accurately detect knock throughout
the engine RPM range. View real time knock
graph on screen and calibrate it easily via
the 4 dedicated keys

PLEX KNOCK MONITOR KNOCK THRESHOLD PER RPM

KNOCK MONITOR v2 AUDIO BANDPASS FILTER
Dedicated Autio DSP

Steep 30 dB band pass filters and
separate processors for knock sensing and
audio filtering effectively isolate knock from
background noise

Higher Order
Harmonic Detection

Easy configuration for monitoring
higher frequencies to minimize interference
from mechanical noise on race engines

Enhanced Analog Outputs NEW!

The 2 analog outputs for connecting the device
to dynamometers, ECUs or other datalogging
devices are now upgraded for 0-5V (from 0-3.3V)

CAN Bus Port COMING SOON!

Export/import knock data easily to CAN Bus
equipped devices like dynamometers, ECUs
and other data logging products. Use the Plex
Knock Monitor in OBD II cars to read RPM and
load inputs.

NEW FEATURE: 3D KNOCK DATA LOGGING

3D Knock Data Logging

Now you can record maximum knock level and
count per cylinder and display both on maps vs
RPM and load on our PKM-Win PC sofware. The
right visualisation to understand knock in depth.
