Easy Installation and Connection for MyChron5 660

Optimal Placement for Easy Viewing

For optimal performance, install your MyChron5 660 in a location where both you and mechanics can easily view the display while working on the dragster engine. We recommend placing it under the engine ON/OFF switch. Secure a bracket to the vertical bulkhead and attach the MyChron5 660 to the bracket.

Connecting the RPM Wire

To ensure accurate RPM readings, connect the RPM wire to the dragster's ON/OFF switch. Typically, the switch has two poles (though some may only have one). The two poles are for RPM and coil. Connect the RPM wire to the coil side of the kill switch. Avoid connecting it to the grounded side of the switch, as this can cause the RPM signal to drop or fail intermittently.

Securing the RPM Wire

Since the ON/OFF switch is usually opposite the bulkhead, drill a 0.2” (5mm) hole through the bulkhead. Insert a rubber wire-holder into the hole to protect the RPM wire from tears and cuts. The RPM sampling frequency for the MyChron5 660 is 50 Hz.

Simple Powering

Powering the MyChron5 660 is straightforward. Plug in and charge the battery. The green light will stop flashing when fully charged, indicating that your device is ready for use.

High-Contrast Display

The MyChron5 660 boasts a high-contrast LCD screen, ensuring excellent readability and flexibility while driving. Choose from two configurable RGB backlight colors to suit your preferences.

An ambient light sensor automatically switches the backlight on or off based on surrounding light conditions, enhancing visibility and reducing distractions.

User-Friendly Keyboard & Display Configuration

The MyChron5 660 features four durable metal pushbuttons for easy navigation and configuration. Designed for simplicity, the system allows you to configure various settings including LCD setup, drive setup, RPM setup, and units of measure.

Easily verify that all sensors and expansions are connected and functioning correctly. Track the number of recorded test sessions, set the date and time, and configure Wi-Fi settings.

Engine Pass Counters

Equipped with four engine pass counters, the MyChron5 660 lets you configure these settings directly from the menu.

Customisable LED Alerts

The MyChron5 660 includes two RGB LEDs that can be set up as temperature alarms, providing instant alerts during your drive.

Comprehensive Data Recall

After each test session, conveniently recall and review sampled data. Access detailed test summaries, check specific test values such as RPM, CHT, EGT, and Overdrive, or view the data in graph mode for in-depth analysis.
