Chip Tuning vs. Performance Tuning: Engine Tuning Benefits

Chip Tuning vs. Performance Tuning

When it comes to getting the most out of your engine, chip tuning vs. performance tuning are common options. Both of these are types of engine tuning, each with their own benefits, and their own costs.

Chip Tuning vs. Performance Tuning

Chip Tuning

Chip tuning originally meant that the chips in the ECU (Engine Control Unit) were removed and replaced with chips that had different software. When diagnostic ports were first introduced to car computer systems they opened the door for engine remapping, or rewriting the software without having to replace the chip. Today, when a lot of people refer to chip tuning, they actually mean remapping.

On the low end, you can buy a chip module that simply plugs into the diagnostic port to change the programming. Although, this can have unpredictable results, since the module isn’t specifically made for your car and driving conditions. To achieve the best results, chip tuning should be done by a professional. After installing a high quality chip, Asher Automotive will often put your car on a rolling road. We will run a series of diagnostic tests using precise machinery while the car’s running. Then, we will adjust the software as necessary.

Performance Tuning

While chip tuning deals just with the software, performance tuning mostly concentrates on the physical parts of the machine. The majority of these hardware modifications or improvements concentrate on the power train, such as the following:

  • cylinders
  • exhaust
  • transmission
  • and more

Performance tuning usually always focuses on getting more power out of the engine.

While car owners can do performance tuning in their garage, they really have to know what they’re doing. Things like boring out the pistons, installing a custom exhaust system and changing the compression chamber size are very difficult procedures. Often times, owners will find that they get the best results when they hire a professional shop to do the performance tuning.

Combine the Tunings

If you really want to get the highest performance possible out of your car’s engine, then you will probably want to combine both performance tuning and chip tuning. Not only will performance tuning allow you to switch out parts, you will also be able to tweak engine parameters to get as much as possible out of the engine.

Once all the physical parts have been fine-tuned, chip tuning will allow you to make sure that the software is lined up to get you the best response possible out of your upgraded engine.
