FAQs

Despite selecting a tuner, my tuner is not working. Why?

The first step is to ensure that the tuner is compatible with the engine that is fitted in your vehicle. After making sure that the tuner is appropriate, be sure to check that all the connections are installed correctly. If there are any loose connections, the tuning may not happen. Make sure that there are no interruptions while the tuner is working. If there is a glitch or any interruption while the tuner works on tuning the engine (duration may vary from a few minutes to a few hours), the tune may not have installed correctly and could cause malfunctions.

How will the fuel consumption be reduced by tuning?

Tuning’s aim is to help the driver reach higher speeds quicker. When the tuning process remaps the ECU of your car, it will help the vehicle reach higher speeds quickly. Driving at higher speeds at higher gear economizes fuel consumption, and therefore, tuning will help with this process.

What is remapping?

Remapping is the process of making changes to the car’s ECU (Electronic Control Unit). Remapping is usually done to get better performance out of the vehicle.

Can changes made during tuning be detected?

Tuning does not make any physical modifications to the car or its engine, and therefore, at a single glance, it is not possible to detect if the vehicle has been tuned unless a physical tuner is left connected in the engine. However, there are ways to detect if the car has been optimized by comparing a tuned car’s ECU with a standard ECU to see if there any differences. In some cases, the manufacturers claim that the tuner can restore stock settings on the ECU. However, once the checksum is modified, any tuning activity can be easily detected.

Does tuning my vehicle have any effect on my insurance policy?

As tuning involves tweaking the vehicle to make changes that were not initially offered by the manufacturer, there will be a change in the insurance policy in most cases. However, the specifics can vary from one company to the next.

Summary

While the traditional school of thought restricted the use of pick-up trucks for transporting large amounts of loads from one place to the next, pick-up trucks have now become more powerful and evolved.

Their purpose is no longer restricted to transportation. People have recognized the powerful engines that are fitted in these trucks the massive potential that they carry to deliver considerable power if pushed.

Pick-up trucks are now often used for towing and off-roading in view of these new revelations.

Therefore, if you own a pick-up truck and want to unleash the entire extent of power from the engine, there is no need for a visit to the expensive autobody shops or dealers. The same can be achieved with the help of tuning devices.
