After several days testing the G25/G27 Brake Mod, here our feelings.
-When I placed it and pressed with my foot,I said "Carlos, this is another world."
It removes red brake pipe which carries the G25/G27 spring inside, and placed the damper / spring with holes compatible with G25/G27.
Disconnect the 3 wires of the potentiometer (it will be disabled), and connect them to wires of pressure sensor.
BLACK / BROWN = GROUND
RED / ORANGE = 5V
GREEN / WHITE = SIGNAL
G27 BRAKE BLACK WIRE - BLACK OR BROWN CONNECTOR PRESSURE SENSOR
G27 BRAKE RED WIRE - RED OR ORANGE CONNECTOR PRESSURE SENSOR
G27 BRAKE WHITE WIRE - GREEN OR WHITE CONNECTOR PRESSURE SENSOR
-Adjust the spring tension to feel the inicial touch of brake. Harder or softer, if you want that the brake back off more slowly or faster.
-Adjust with 1 turn 360º of Allen screw of hydraulic tank to feel harder or softer the second part of way of brake. Min 0º. Max 360 º. And all intermediate positions.
-The feel is like a real brake. You feel the brake has an internal hydraulic circuit in and above all, that when you release the brake, it rises a little slower and very smooth, thanks to the damper that goes inside the spring.
With the allen screw (adjustment hydraulic tank), you adjust the feeling of the second part of the braking (which is exponential) .
-Leave it softer, so there is more travel in the pedal
-Let him harder, so that there is less travel in the pedal, and note the force much more
That means :
-You can put the brake pedal with 1 cm of way and you need to make more force to brake (only force, without the pedal moves)
-Or you adjust it to move the pedal aroudn 3.5 cm (the maximum allowed) and you feel the force at the end of de pedal.
-Or all the intermediate steps, more way, less way, braking too hard or less hard.
So you forget to block brakes in the simulator.
-It is tested with the pedals connected directly to the wheel G25/G27, leo bodnar cable and similar mainboards/controllers. Goes perfectly in all simulators (iRacing, rfactor, AC, Nkpro, RBR, GTR2 ...)
-The pressure sensor has a resolution of 24 bits.
-It is recommended to connect the pedal to leo bodnar cable (10 bits equivalent to 1023 steps). Or the BU0836 who is 12 bits (4095 steps). Well, of course, if you have a controller with higher resolution, much better. Simply because more resolution, braking will work better in the simulator.
-In iRacing, it is important to change the BRAKE FORCE CURVE FACTOR Options / controls to 0 so that the braking is detected as sends the pressure sensor.
-Finally, remark that if someone (which I doubt) is accustomed to braking with potentiometers, just leaving the original connectors cable connected to the potentiometer G27 brake and you can adjust the hardness, travel and feeling the mod with the settings mentioned above.
(There will be avaliable the same brake mod but without pressure sensor, cheaper.)
We will upload new photos and installation guide.
We are manufacturing the mods of pre-orders. Coming soon more news.
