Phormula knock detection offer the best knock analysers currently on the market. At R-developments we are proud to announce that we have become the Dutch dealer for the whole Phormula range. We have tested the monitor in several cars with great results. It detects knock in an early stage which will save your engine in the long run. Engine knock can cause severe damage to pistons, cylinder heads and even the complete engine block. Thats why we reccomend using a knock analyser to monitor your engine in the best way possible.
What is Knock?
Knocking or detonation occurs when unburnt fuel in the combustion chamber explodes instead of burning in a controlled manner. When engine knock is occuring the pressure in the combustion chamber rises dramatically to levels that can destroy engine components in a few seconds.
Phormula KS-3
The KS-3 is probably the most advanced engine knock detection system on the market. The KS-3 actively filters and processes engine signals using a dedicated knock microprocessor. These signals are processed and displayed on a wide angle clear LCD display.
How does it work?
The KS-3 monitors engine knock levels and can be configured to alert the driver via a visual and audable warning. The KS-3 can be used as a hand-held device or permanently mounted to the dashboard. The KS-3 is configurable for frequencies between 6 and 9 kHz. The system includes high quality Bosch Wideband Knock Sensor, Sensor Plug, Shielded Signal Cable, Mounting Kit and Power Supply Cable.
Phormula KS-4
The KS-4 contains all the great features of our KS-3 plus:
- 0-5v Analogue Data Out
The KS-4 contains a true 0-5v analogue data output. Data output rates are configurable at up to a blistering 100 samples per second and fully compatible with all datalogging software, Dyno’s and ECU’s.
- External Trigger
The KS-4 external trigger function adds further flexibility by allowing you to power your own external warning devices when the KS-4 alarm is triggered. - Sensor Output
The signal from the sensor can be easily routed to another location within the vehicle. This can provide a more convenient location for the interface to the knock analyser pro.
