The Turbo Timer Type-1 features a light blue LCD backlit display and has the same basic timing and voltage features as the Type-0 plus several monitoring and measurement functions.

The Turbo Timer Type-1 features an Auto mode for the timer function allowing the Turbo Timer to automatically calculate optimum idling time according to the most recent driving pattern. Vehicle speed and RPM can be displayed on the Type-1's LCD monitor and a speed warning level can be set. A two-stage RPM warning can also be set and used as a shift indicator. When a warning level is reached the Type-1's LCD monitor will blink and an audible beep will sound.

The HKS Turbo Timer Type-1 also features various measurement functions including 1/4 mile timer, 0-60 timer and a stopwatch function that can be used for lap timing. The Turbo-Timer Type-1 can read in either MPH/SAE or KPH/Metric.
