Best Car Tuning Software In 2021 (Our Reviews & Comparison)

21st century car performance goes far beyond upgrading components or retooling existing ones. Engine systems, transmissions, fuel systems and exhaust are all controlled by a car’s central computer called an Electronic Control Unit (ECU). Modern cars are tuned via programming the ECU using sophisticated computer software to achieve the highest possible degree of precision. Which car tuning software package is the right one for you? We’ve reviewed the current top five so you can make the best choice for your tuning needs.

Our Recommendations for Car Tuning Software

1. TOAD Pro

Any car enthusiast will tell you that a custom-built car will always perform better for a skilled driver. Moreover, when their racing team is accurately diagnostics and customizing tuning, a relatively tame car can become a real street demon. TOAD PRO was built to be a consumer/home mechanic tuning solution that allows any mechanic to diagnose, reprogram and refurbish their vehicle.

Features

Here are just a few things you can do with TOAD Pro:

  • Get an accurate picture of your vehicle’s overall health.
  • Diagnose and repair common issues.
  • Edit/reprogram any vehicle’s ECU data values. 
  • Fine-tune your vehicles performance
  • Establish optimal fuel economy
  • Create custom dashboards, charts, gauges and graphs that allow you to diagnose and correct more issues on your own.
  • Troubleshoot your own vehicles and save on hefty diagnostic fees from dealers or local auto shops.
  • Check and adjust shift timings for better acceleration performance.
  • Get accurate CO2 emissions data without needing expensive additional equipment.
