PerfExpert - Car Dyno HP Test

Once I go through the calibration routine, it gives me no choice to move onto a test-only a “back” button that takes me back to the “calibration” button, forcing me to start over, in a circle. What may I be doing wrong?

I have tested numerous apps which some where OBD2 connected and some like this one, independent of OBD2 being a stand alone one. I was surprised to find out how accurate this app in comparison to a standard dyno. In fact, I feel that this app gives me a more reliable reading in comparison to commercial dyno where parameters can be adjusted by the operators which may not be in line with the proper characteristic of my car. One improvement that I would suggest is: to allow the user to choose the 2 or 3 results that will show up as the “average “ and allow to present this “average “ in a graph. Great app.

Trying to put all the numbers in properly to dunk the car but I have a 2017 civic lx hatch that is a CVT transmission. I have full bolt ons and running full e85. In the fuel option it only lets me choose between gasoline or diesel and the second problem I have is that I don’t really have any defined gear ratios besides my first gear final drive and reverse. Would the app still be accurate missing those parameters?
