Setting car model (harness)
This turbo timer is exclusively for turbo vehicles that start the engine using the ignition key.
10 generations with turbo cars
Turbo timer, evolution of reliability 10th model released
Starting with the essentials for turbo cars...
The turbo timer
was developed to perform after-idling on turbo-equipped vehicles and prevent the bearings of the turbocharger from seizing up.
Aiming for BIG POWER & SAVE ENGINE...
1982-1985
All turbochargers are exposed to high-temperature hot air from the exhaust gases. Therefore, if the engine is suddenly turned off, it may cause damage or damage to the turbine body. After-idling is a must to ensure the longevity of the turbine. In order to meet these market needs, we have developed a turbo timer that can be used with confidence.
Nowadays, turbo car models have become the norm
1985-1987
A turbo vehicle that enables small displacement and high output. Manufacturers are also entering the era of turbos, where they are releasing turbo model cars one after another. Then, the design was redesigned to match the compatible model. Adopts a design that matches the dashboard. The functions have also improved operability and visibility, increasing the need for after-idling.
Pursuing evolution from the pioneer model
1987-1989
The ever-popular turbo timer has been made easier to use, lighter and more compact.
Easy setting with push switch. The display window is illuminated for easy viewing, improving visibility. 12V/24V shared.
Luxury model “Quest”
Limited Model
The first HKS turbo timer model to use a liquid crystal display.
The LCD display flashes green when the timer is on standby and flashes red when the timer is in operation, and counts down in 1-second increments.
Also, when the countdown starts, the alarm sounds and you can confirm that it is working.
Adopts a streamlined design to pursue a sense of unity with the interior.
1989-1994
The main body case is made of authentic ABS resin. In addition to the timer function, this model has a sophisticated design that takes into account the interior of the car.
2 modes, 2 ways, 2 crystals
1994-1996
Normal display and active display can be selected in timer mode and integration (ADD) mode.
The integration mode allows you to understand the engine operating time, which is extremely useful for maintenance that cannot be determined based on mileage.
Emphasizing the time system, it has a built-in crystal for operating the main body and a crystal for measuring time.
In addition to 2-mode/2-way display, it is equipped with a timer memory function.
1996-2000
You can select and set 14 different idling times. It can be set for a long time to prevent unnecessary idling.
Furthermore, the newly added memory function makes it easy to switch after idling depending on the driving condition, and it is possible to set 3 memories and 4 patterns.
2 types to choose from depending on usage, linear timer function
2000-2008
There are two types: TYPE-1, which is equipped with many functions and can be enjoyed, and Type-0, which is equipped with only basic functions.
The mode selection switch allows you to adapt to various situations. This is an all-round timer that is not limited by the specifications of turbo cars.
Pursuing functions and size that suit the compact era
2008-2018
By making it a separate type, we have increased the freedom of installation location. Furthermore, we pursued a sense of unity by using the same design and configuration (separate type) as EVC-S. In addition, the industry's first push start model has been added to the simultaneous model.
We have undergone numerous model changes and developed a variety of types.As
a result of pursuing what is truly needed...we have arrived at a simple model that specializes in timer functions.
10th ModelA simple model with an emphasis on operability, born from a history of 35 years.

Car model: Turbo car (general purpose)
Code No.: 41001-AK012
Price (tax included): ¥10,780
Functions focused only on after-idling
Pursuing simplicity and ease of use
Simple, easy-to-use operation that allows you to change settings by pressing a switch.
- DC12V negative ground vehicle only (main unit operating voltage: DC10V to 16V)
-
Equipped with large capacity relay
Ignition system: 25A / Accessory system: 25A
- Main unit standby current: 10mA or less
- Operating temperature: -20 to 60°C (-4 to 140°F)
- Setting time: 1, 3, 5, 10, 30 minutes
-
For example , after idle for 1 minute, even for everyday use.
-
Performs idling that corresponds to everyday use such as city driving and commuting.
This is useful when you don't have time to attend after-idle.
-
For example , 3 minutes is a valid setting for after-idling after driving on a highway.
- After-idling, such as when driving under continuous load on expressways, cools down the highly heated turbine and engine oil, and turns the engine off without putting any strain on the engine or turbine, improving the durability of the engine and the durability of the oil. It has the effect of increasing
-
For example , a setting that is effective for 5 minutes after idling when driving on a circuit.
- The turbine and engine are at their peak due to the high load/high engine speed that is close to the engine's limit. To avoid accidentally stopping the engine after driving under high load, the turbo timer allows you to perform a reliable after-idle.
-
For example , for 10 minutes, to maintain the temperature inside the car when shopping.
- Since you can lock the door while the engine is running, you can maintain the temperature inside the car and reduce the burden on the battery caused by the hazard lights, giving you peace of mind when you leave the car for about 10 minutes.
-
For example , it can be used for 30 minutes to check the temperature inside the car in summer or winter.
-
After-idling can be set for up to 30 minutes. Depending on the parking location, you can idle for long periods of time and maintain/secure the temperature inside the vehicle.
(Please note that there are some areas and facilities where idling for long periods of time is prohibited due to local regulations.)
