It is knock gauge. Brand new.

Hand made.

Very bright LEDs. It is clear when light off.

It is hard to miss detonation signal.

Dimension: 65mm x 50mm x 20mm (L x B x H) exact dimension may vary.

Weight is ~70g

Wire Length: 1m by default. Longer cable have exceed weight restriction for shipping cost. Contact me if you need longer wire.

Mounted in a plastic box.

SENSOR IS NOT INCLUDED.

Customers use sensors:

Knock Sensor for Audi & VW OEM# 0 261-231-038, KS16 ;
Honda #30530-PV1-A01;

You can prevent damage of your engine by monitoring detonation
signal. It appear if air-fuel mixture is wrong for some conditions. This
gauge monitor detonation at begin. So you have some time to react and
save your engine. That gauge work with noise signal at unique frequency.
Detonation of most car is near to same frequency. That mean that this
gauge fit to all car. If you are unsure in it do not hesitate to ask me
about it.

Very useful in race condition where no time to look at other gauges
(EGT, A/F and etc.). It could be mounted straight on wheel or dashboard
or anywhere where driver could see that gauge. you do not need to focus
sight to gauge to see what result shown by device. When detonation
appear you will see very bright led light on. Led brightness is bigger
then stop signal of some car. You couldn't miss that signal.

You can choose other combination of led color of green, blue, yellow, orange, red. (detonation signal RED ONLY).

Analog output is optional. It costs 20USD in addition. You can use
output of gauge as input to your ECU to manage ignition or fuel if you
ECU has AUX input. Also possible to use with some retarder or ignition
controller.

Options for output:

1. As switch to ground;

2. As switch to +12V;

3.As 0v + 5v output;

Let me know if you need output.

Troubleshooting:

1. Q: Gauge is connected to sensor and power supply. One green LED
lights on only. Engine running at idle or accelerated. No more LEDs
lights on in additions.
A: Check first green led when accelerating.
It must change brightness. If not then check wire connection of sensor.
Especially ground connection of sensor. Resistivity of it must be lower
then 100Oms.

2. Q: Gauge not work at all.
A: Gauge is tested twice before
shipping. First time after assembly, second time after fitting in to
plastic box. It is impossible that gauge is damaged in post system if
plastic box is OK. Check wire connection. Or it possible that your OEM
knock system not compatible with this gauge. Try to use separate knock
sensor.

WARRANTY. If you gauge stop working contact me first and we will
discuss about it. If gauge was damaged by car crash warranty void.

So this box coupled with an audi detonation sensor can listen for knock at all RPM ranges?
