What does tuning involve? 

Performance Tuning unleashes the power already available within your vehicle (about 10-15% increase in horsepower/torque) through software/computer upgrades via the Autologic.

Before tuning any vehicle, it is first necessary to complete a diagnostic scan to ensure there are no issues which may affect the performance upgrade. Once complete, the relevant performance tuning software is simply uploaded to the vehicle through the Autologic tool via the OBD-II diagnostic port.

The re-tuning process involves the electronic removal and re-installation of a more refined and enhanced version of the vehicle’s computer programming. As ECU’s cannot communicate during the upgrade process, the fault memory is cleared and rechecked at the completion of the upgrade, before the newly tuned vehicle hits the road.

Why do the manufacturers limit the output of their engines? 

The standard manufacture tune is a compromise of hundreds of factors. Principally, the manufacturer must ensure a high degree of engine reliability across the worldwide market, taking into account factors such as:
  • Fuel Quality
  • Different servicing schedules
  • Different operating environments, such as altitude and terrain
  • Local legislation with regard to power output and emissions
  • During testing, manufacturers ‘tweak’ the tunes constantly to achieve individual results for individual tests, thus compromising the overall smoothness of the original tune. Autologic Performance Tunes are optimized for US driving conditions.
How will emissions be affected? 

All Autologic Performance Tunes are tested to ensure that they comply with US emission laws. Additionally, your vehicle is guaranteed against engine light illumination, emmisions or mechanical issues relating to the performance tuning process.

Is the tuning process reversible? 

Yes. In the unlikely event that you require the Autologic Performance Tune to be removed, the process can be reversed without any side effects.

Are there any physical changes to the vehicles? 

No, with the exception of the BMW Mini Cooper S. Most Autologic Tunes are ECM software downloads ONLY. We have two different tunes available. The first is software only, with no physical evidence that the vehicle has been altered in any way. The second, more aggressive tune, has been optimized for a smaller, supercharger pulley.

How do you winterize your car? 

Climate changes don't affect just you―they also affect your car. In regions that don't enjoy mild winters, you wouldn't dream of heading outside without a heavy coat if the wind chill brought the temperature below freezing. Don't expect your car to function properly without some attention to its winter needs, too.

How to control your engine oil in the winter?

The oil in your engine changes depending on how hot or cold the engine is running. Because the outside temperatures will influence the internal temperature of your engine, you need to make sure you're using the proper oil for the conditions.

During the winter months, if you live where temperatures get below freezing, you'll want to switch over to thinner―less viscous―oil. If you run a 10W-30 in the summer, for example, try moving to a 5W-30 when changing your oil in the fall or winter. If you are in doubt, refer to your manual or the manufacturer.

What is the correlation between cold weather and battery capacity?

It isn't only your engine that doesn't like to start in the winter. Your battery capacity is reduced by the cold weather, too. A thorough inspection of your battery, cables, terminals, and fluid will help you make sure your car is ready for the winter.

Check over the battery cables for cracks and breaks. The terminals should fit snugly with no loose connections. You can check your battery fluid by uncovering the refill hole (or sometimes holes). If the level is below the bottom of the cap, refill with distilled water.

To read the level of charge in your battery, you will need to turn the engine off. Some batteries have a built-in hydrometer eye that tells you the amount of voltage remaining in the battery. If you prefer, a handheld hydrometer can be used to collect the same information
