What does TSI mean in TRANSPORTATION

Two Speed Idle works by monitoring various sensors within the vehicle such as coolant temperature, throttle position, and intake manifold pressure. Depending on these readings, the computer will decide which idle speed should be used in order to save fuel or increase performance based on the driver's needs.

The main benefit of having Two Speed Idle is improved fuel efficiency. By idling at a lower speed, more fuel can be saved over time as compared to an engine that would normally run at a higher rate regardless of what's going on around it. Additionally, this feature also helps reduce emissions since an engine running at a slower rate produces fewer pollutants than one running at its full capacity all of the time.

Not all car models have Two Speed Idle available as an option from the manufacturer, but there are aftermarket kits available that allow owners to install this feature onto their vehicles if they wish.

No maintenance is required for Two Speed Idle systems, however it may be advisable to check your owner's manual or contact your local dealership in case any additional service is recommended by either one of them.

Installing a Two Speed Idle system into your vehicle can be done with relative ease if you have some knowledge about auto mechanics and electrical wiring skills, but it is not recommended unless you have experience with this type of work due to safety reasons and potential damage that could occur from improper installation or wiring errors. We suggest seeking out professional help from a qualified mechanic if you are not confident about doing it yourself.
