You can prevent damage of your engine by monitoring detonation signal. It appear if air-fuel mixture is wrong for some conditions. Device monitor detonation at begin. You have time to react and save your engine. Device work with noise signal at unique frequency. Detonation of most car is near to same frequency. That mean that this device 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.
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. Resistance 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 other knock sensor.
