Shift-light Adjustable Tachometer for Performance Racing Cars

TCM188 Tachometer Technical Specifications and Performance

RPM Measurement and Signal Response Performance

This tachometer covers a full measuring range of 0-8000RPM, compatible with all common 4, 6 and 8-cylinder gasoline vehicles. Every unit undergoes 72-hour continuous RPM signal aging testing, with a response delay of less than 0.05s. It delivers real-time engine rotation speed data for both daily driving and racing scenarios. The product holds ISO 9001, IATF 16949, CE and E-MARK certifications, complying with international automotive quality and safety standards for commercial procurement.

Adjustable Shift Light and Display Design

The unit features a built-in SET rotary knob, allowing users to set the shift light alarm threshold within 2000-8000RPM. A bright red LED flashes when the set RPM is reached, to remind drivers of shift timing and prevent engine operation beyond recommended RPM ranges. The dial adopts a high-contrast layout with white scale lines and a red pointer on a matte black background. It provides a viewing angle of nearly 170 degrees, with reduced reflection under strong sunlight for clear RPM reading in various lighting conditions.

Durability Testing and Environmental Adaptability

The tachometer uses an integrated black plastic housing. Each finished unit passes continuous vibration testing and temperature cycling inspection within -20℃-70℃ before shipment. It can withstand engine vibration and temperature fluctuations during driving on rough road surfaces. The product is equipped with a foldable multi-angle metal mounting bracket, supporting horizontal and tilted installation on uneven dashboards. It comes with a complete color-coded wiring harness, simplifying the wiring process without additional circuit modification.
