pedal set calibration




Calibration for the PT-1 in batches "5" and later

Scroll down for earlier batches

If you have a pedal set from batch #5, calibrating your pedal set is much simpler. Make sure to follow the instrucitons laid out in the video below. With that said, there are a few things you need to be aware of before watching the video...

  • DO NOT calibrate within DIView unless you have set up your pedals mechanically first. This ensures that you do not have to make any adjustments within DIView afterwards

  • The inputs in the video are a bit jumpy. This is due to interference from the power brick used to power the laptop that was used to film this video. This shouldn't happen on your PC

  • Even if you are using iRacing, please make sure that you turn your potentiometer so that it reads almost zero within DIView. This will ensure that your pedals have the proper rotation

  • Older sims may require you to edit the numbers within DIView in order for your inputs to read from 0-full. Most sims do not use RAW data, so tweaking the numbers may be required

  • The allen wrench needed to loosen the set screw on the potenitometer arm is in the accessories package shipped with your pedals



Calibration for the PT-1 in batches "4" and earlier


IMPORTANT: If you have batch 4 pedals, your X and Y axis may be reversed. Your pedals will still function normally after calibration. We apologize for this confusion. 


ProtoSimTech has encorporated the DSD 12-bit controller board into the PT-1 pedal set. This 12-bit controller board has some unique capabilities. You will have the ability to not only tweak the load cell's sensitivity using this board, but you will also have the ability to set a custom "focus" area for each potentiometer, separately.

For example, if you want more travel on the throttle pedal than on the clutch pedal, you can do that! Below is a set of instructions on how to calibrate your pedals. Please make sure to follow these instructions carefully. Each step must be done in order.

Note: These pedals have been tested, but not calibrated. We recommend that you place the pedals where you like them, make sure they are properly attached to your rig, and then adjust them to suit your own driving style. Once you are satisfied with the pedal's physical movement, you can proceed with calibrating them. Make sure that you are comfortable with how the pedals feel before calibrating. If you decide to make changes later on, make the proper adjustments to the pedals, and then skip to step 5.

Note 2: If you do need to re-calibrate the pedals after making adjustments, set the axes MIN and MAX numbers back to 0-4095 within the DSD Enhanced configuration utility and hit "Update". This will reset the potentiometers back to their "default" resolution. You will not have to go through the Windows calibration process if you've already done it once. The purpose of the Windows calibration is to ensure there are no anomalies during normal operation. 


Connect the controller board to a PC using a standard USB cable. After you have connected the board to the PC, open "Control Panel" and find "Devices and Printers". Open "Devices and Printers" and look for the icon that says "DSD 12bit Controller - ES"



Right-click on the DSD 12-bit controller icon and choose "Game Controller Settings". A box will pop up with the game controllers that are currently connected to your PC. Click on "DSD 12bit controller - ES" and then hit "properties". This will bring up another box that has two tabs labeled "Settings" and "test". Click on the "settings" tab and hit "Reset to Default", then hit "Calibrate". Another box will pop up. Hit "Next" and then "Next" again. This is the beginning of the calibration process. Make sure to select the checkbox that says "Display RAW data". This will allow you to see the actual numbers during calibration.



This first screen is for a D-pad, which we will ignore. Hit "Next" again, and then "Next" one more time. This next screen is for the Z Axis, which we will also ignore. Hit "Next" again. Now we are at X Axis screen, where we can begin to start pressing our pedals. begin by pressing the clutch pedal a few times all the way down.

You should now see some movement in the blue slider in Windows. Below the blue slider, you will see "X Rotation" and then numbers beside it. As you press on the pedal, this number will change. While not pressing on the pedal, write down the number you see (you will need these numbers later). Now press the pedal all the way down, and then write down the number you see (while the pedal is still pressed down all the way). Once you have both numbers for the X Axis, hit "Next". The next screen will be the Y Axis for the throttle. Repeat the same process for the throttle pedal. Make sure you have both the MIN and MAX numbers for each of the pedals.


Hit "Next" again. We are now at the screen for the Z Rotation. This is for the brake pedal. Press on the brake pedal until you have verified that it is working properly. Press on the brake pedal as hard as you feel you might press it in game. You will be able to tweak the resolution for the brake pedal in programs like DIView or DXTweak. Keep in mind that iRacing uses RAW data, so these programs will not work in iRacing.


Download the Enhanced 12-bit controller configuration tool here. Unzip the program and run it. You will then see a dialog box pop up with two tabs - "Buttons" and "Analog Axis". Click on the "Analog Axis" tab.


On the "Analog Axis" tab, you will see two buttons labeled "Configuration Axis 1,2,3" and "Configuration Axis 4,5,6". The potentiometers (Throttle and Clutch) are connected to Axes 4 and 5 on the controller board. This is important, as you will be configuring these axes for calibration. This is the point at which you will need to have the numbers that you wrote down for the throttle and clutch pedals. Click on the button named "Configure Axis 4,5,6". A box will pop up named "Analog Axis Config".


We'll start with the throttle pedal (Analog Axis 5 -Y Axis). For the "MIN" value, enter in the lower number from the throttle pedal (it's the lower number for the Y-Axis). For the "MAX" value, enter in the higher number from the throttle pedal (it's the higher number you wrote down for the Y-Axis). Then move on to "Anaolog Axis 4 - X Axis". Enter in the "MIN" and "MAX" values that you wrote down from the clutch pedal. Once you have all the numbers entered into the correct boxes, hit "OK".


Hit "Update" on the configuration utility, and a box will pop up that says "Configuration Set". Hit "OK" and you're set!
