ProtoSimTech PT2 Pedals

Overview

Excellent quality load cell pedals at a then very reasonable price (2013-2022)
The clutch on the PT-2s has a novel spring-loaded physical resistance mechanism to approximate what a clutch feels like in a real car
Probably surpassed by other pedals at this point but excellent pedals and I'm still using them in 2025
ProtoSimTech closed down in 2022
Replacement parts are no longer available for purchase from ProtoSimTech but many of the smaller pieces are off-the-shelf pieces and there's a good chance you could buy replacements at Home Depot, Amazon, or other places
- I wouldn't worry, I haven't needed any replacement parts since I bought mine in 2018
Other parts like rubber washers can be replaced with parts from Heusinkveld who make their own high quality pedals and parts

PT2 Adjustments and Calibration [Video] - Batch 1-3 with Sensitivity Potentiometer Box Adjustment
- DIView for USB Devices - Software to View and Calibrate USB Inputs
DIView Brake Load Cell Calibration [Video] - Video is labeled for "Batch #5" but it applies to all batches as it's at the USB inputs level.
Calibration for PT2 batch #4 and later [Video] - Batch 4+ with Sensitivity Software Adjustment
- Configuration Software

Sensitivity Potentiometer Box Adjustment:
- Heavier brake feel: Turn Left - Decrease Sensitivity
- Lighter brake feel: Turn Right - Increase Sensitivity
Recommendations:
- Start in the middle
- Adjust by 90degs either way and test, then by 45degs and test, then by 22.5degs and test, and so on
- I am somewhere between straight left and straight up ie. 25-50%

tl;dr I removed the screws on my controller box and it started applying the appropriate heavy feel per the knob rotation
- Something must be getting compressed in there and it stops working for some reason
At some point, my brake load cell seemed to be stuck on the easiest, lightest setting regardless of what I set the control box knob to
After unscrewing the controller box to see if anything was disconnected, or looked broken, the appropriate brake pressure / heavy feel started working again
Using Diview, I could see the actuation number and gauge based on how much pressure I was putting on the pedal
Now it takes significant brake pressure to reach 100% brake, which is what I want
Update:
- Still a problem. Appears to be frayed wire strands on the small potentiometer board connections touching each other
- Separated them with electrical tape and that seems to have fixed the problem for now
- I will be upgrading the existing BU0836-LC Load Cell Joystick 12-Bit Controller to a Load Cell Interface LC-USB 16-bit
  - Bonus: Instead of a potentiometer knob, the brake feel can now be adjusted in software using Bodnar Configuration Software which is available on the same product page
- I managed to contact Chris from ProtoSimTech, as well as Bodnar support, and they both indicated it was a valid upgrade path for the pedal inputs
- Looking forward to the higher 16-bit resolution as 12-bit (4096 steps) just seems a little too low resolution to me
