Load Cell Problem in Club Sport V3 Pedals
John Mustanich Member
I just took delivery of the Club Sport 2.5 base and the V3 pedal set. Prior to that I was using a Thrustmaster T300 RS GT with the T3PA pedals which I modified by adding a Ricmotech load cell. When using the load cell the pedal travels one inch before it hits the load cell stop at which time braking begins. Pressure alone changes the brake force from 0 to 100%. The pedal itself doesn't move. The Fanatec V3 are advertised as having a 90kg adjustable load cell, however, mine act like there is no load cell installed. Braking begins when the pedal is depressed and reaches 100% when the pedal reaches the mechanical stop. The only way to modulate the brake force is by altering the position of the pedal. This is NOT how a load cell works. Did I receive a faulty set, or are other users experiencing the same problem? I have an open support ticket and am waiting for a reply, but I'd sure like to know what other users think. Thank You.
I don't really understand why you suspect duplicity in the answers you have received here.
I'm not a Fanatec official, just a customer like you (although I have developped a good relationship with the team over the years) so what I will say here is just my opinion but you can't say the default CSP brake settings is position based.
It is however true the feeling with the default settings can look like a position based pedal (driven by a potentiometer or hall effect) due to the long pedal travel but it is still driven by pressure (there is no potentiometer or hall sensor on this pedal, only a loadcell that you can see without disassembling).
Also position based pedals driven by potentiometer (or hall sensors) are most of the time linear (x% of pedal travel = x% of output signal), and I don't think the CSP output signal is linear VS pedal travel even at the default settings.
I have always thought this default setting was a compromise made to make the transition easier for people coming from travel-based pedals (very likely the majority of Fanatec new customers). So this is a default compromise and it can be changed by using different elastomer springs for people who prefer a stiffer brake pedal (and with less travel too), closer to real race cars (after using the default setting for a long time I have this performance kit installed too now, and it was a game changer for me).
It is true the CSP product page could explain a bit more about this feature for new customers who are not used to Fanatec products. The CSPv3 already has a built-in preload system to stiffen the brake pedal but the performance kit allows to go beyond that, with even more stiffness and less pedal travel. This kit was just released (and designed) after the pedals were released, this is maybe why this performance kit is not well described on the pedals product page itself (it is just listed as a compatible product at the bottom of the page, so yes this CSP product page could be updated to explain more about this kit when buying the pedals).
A completely static pedal (driven 100% by pressure) is theoritically possible too (with no dampening material at all before the loadcell) but then the risk of damaging the loadcell sensor would be greater I guess. It could work without issue for someone staying within the sensor specs but someone else applying more strenght would then risk to damage/break the sensor.
Beside this Fanatec has always been listening to customers' feedbacks. They won't accept every suggestion of course, and they can also be hard to convince sometimes, but they do hear feedbacks from their customers and improvements are made when necessary. Some of their products, like the H-shifter, have even been designed based on the most wanted features and materials after asking the community. So immediately suspecting duplicity may just not be the best way to share your concerns after an official has tried to help you. I personally find the answers you have received here were transparent, many other companies wouldn't have told you why they don't document anymore this or that setting in their user manual
I will say the tone on here feels harsh on all sides and I can understand the frustration. I can understand John's frustration, as when you spend so much money on Fanatec equipment, you expect to see the gains over alternatives pretty quickly. I've been messing around with settings on these pedals for almost a week now and am still learning and figuring it all out. It's frustrating to hear that there are various tips and tricks, especillay that are not in the manual, to achieve the right feel when the equipment is relatively sensitive/fragile and you can easily void the warranty and Fanatec is not highly regarded for it's customer service on these matters. An example of how the manual could be improved would be to have a flowchart or diagram showing what changes a user wants in feel, and how to adjust those, along with disclaimers about what changes/modifications will void the warranty.
It also sounds like there's miscommunication here. I will say pretty difinitively that there is something going on that causes the pedal to emulate a position sensed device instead of load cell, and I can't yet figure out why. But when I switched out springs (rubber pieces) in the brake, it took significantly more force to reach 100% brake force. This is NOT how a load cell should work. the only change should be the final position when you hit a given force. This leads me to believe that something else is going on, maybe there is added friction somewhere? Maybe the rubber springs are expanding and binding up and therefore not transmitting all of the load to the load cell? Maybe I didn't apply enough lithium grease? But the manual does not specify how much to apply... But the point is, I obviously know it's a load cell and I know how it works, but some kind of phenomen is preventing it to act purely as a load cell. The manual doesn't help figure this out, and for the most part, I'm struggling to troubleshoot it through the internet. So on matters like this, it would be nice if Fanatec were more helpful, clear, etc. Also the trial and error process for adjusting all of this is a bit of a pain considering the process involved to make edits to the physical setup, which I should add also involves removing the pedals from a rig because of how the equipment is accessible from underneath. So it would be nice if the manual maybe gave numbers specifying things. Maybe load/displacement for certain spring combinations? Or even a quantified increase in travel/stiffness instead of qualitative soft/medium/hard. And the crux of all of it is that given the amount of variability and adjustment, and vagueness of the manual, it's very difficult to know if something is or is not functioning as intended.
Is the problem here that the pedal auto calibrates???
