Introducing PerfExpert car database

on Wednesday, 16 March 2016. Posted in Announcements, Using PerfExpert

Fill in your car profile faster thanks to our car database

Setting the right values for all your car profile parameters is very important to get realistic results with PerfExpert, especially for Dyno tests. And most of the time, searching the web for all the information to fill in your car profile properly can be tedious. To help you in this task, we used to post car sheets information on our support forum when you requested it. Now, since PerfExpert for Android v2.0.1, you have the possibility to get your car profile completely filled with values coming from our car database, without the need to enter them manually.

Values from our database correspond to 100% standard cars (stock) with most common options. We encourage you to always review all parameters to ensure they match your own car, especially weight, wheel dimensions and pitch.

At the car profile creation, you can select your exact car model from our database. Don't worry if it's not listed : just choose "Other..." and tell us your car model the most accurately possible so we can update our database accordingly.

Once the car profile created, it's pre-filled with values from our database. If some parameters are not yet available from our database, they will be left undefined in your car profile, and it's up to you to enter them manually if you know them, or to ask us for some help (via the "Need help..." button) if you don't know them. At this point, if you requested help from us, we will search for the right information to update our database and then we will update all the undefined parameters of your own car profile. So if you want to have your car profile automatically filled, we suggest you to leave all undefined parameters empty, waiting for us to update them.

Don't forget to review parameters to ensure they match your own car, especially the following ones :

  • Car weight. As it depends on your car options and modifications, it's better to rely on the curb weight mentioned on your vehicle registration document.
  • Wheel dimensions. Simply check the size mentioned on your tires.
  • Pitch. If you've modified your car suspensions, you will have to adjust this parameter accordingly.

Highlight your PerfExpert vs Chassis Dyno comparison

Send us your comparisons to better convince the most skeptical ones about PerfExpert accuracy

Highlight your PerfExpert vs Chassis Dyno comparison

Most people find it hard to believe that a smartphone application can measure power and torque with an accuracy very close to chassis dynos, without any connection to the car or without any external measuring equipment. They generally think of a hoax, because they cannot imagine the real potential of the modern phones sensors, especially when they are combined with powerful algorithms and calculations. Thus, providing them the proof with "PerfExpert vs Chassis Dyno" comparisons seems to be the solution.

What could be better than seeing this proof brought by other car enthusiasts who tested PerfExpert by themselves?

If you carried out this kind of tests you can contact us to transmit us your results, by sending us the following elements :

  • A copy of the full report of the chassis dyno result, in other words, the result sheets, perfectly readable, scanned or photographed
  • An Image export of PerfExpert measurement curves, and, if possible, with two PerfExpert tests carried out under the same conditions (same road, same direction, same starting point, same day)
  • The links towards your tests on the Web PerfExpert Network
  • And for the fun, if you agree, a beautiful picture of your car, outside and/or on the chassis dyno! :) We will hide the license plates if they appear.

We will gather them in our Google + collection of PerfExpert vs Chassis Dyno comparisons.

Speaking about PerfExpert around you and showing that it is a reliable application when it is correctly used allows us to keep on improving it and creating new features! As a user, you now know how to answer those who ask you about the application's accuracy and reliability compared to chassis dyno's. In fact, this is often the first question people ask when they discover that the PerfExpert application allows them to measure your car engine’s power and torque using only your smartphone!

Here is an comparison example from our collection :

PerfExpert Car Dyno=> Power : 301cv / Torque : 370Nm

Cartec Chassis Dyno => Power : 300.5cv / Torque : 371Nm
