Hi, I'm new here...
I didn't have the pedal problem on DFGT, it actually works pretty well...
But I'm obsessed by the pedals of G25/27.
And I read someone in the forum used the DFGT cable on G25 pedal, I liked that idea alot.
DFGT Wheel with G25 Pedal, just sounds really cool....
So I bought the G25 pedal from the auction website for a cheap price, and start the modification...
(A recycle shop accidently bought it without wheel inside the box, they were pissed and sold it very cheap..)
I opened the case on both pedal, and putted tag on each wire for memorize purpose, and tried different combination for 3 hours, it wasn't easy.
A little complaint though, the pedal of DFGT is really cheaply made, a little annoying when re-seal the case.
Below is how I managed to got it work, from my memory only..
DFGT Pedal: PCB board> 2,_,H (red wire, white wire, black wire) , 4,_,H (red wire, green wire, black wire)
G25 Pedal: PCB board listed 2a,_,Q, 4a,_,Q.
Clutch is 6a,_,Q, but DFGT cable only support gas, and brake, no clutch...
When I plug DFGT pedal cable on G25 pedal, plug the wires 2,_,H (DFGT) to 2a,_,Q (G25), that is, 2 to 2a, _ to _, H to Q...
In game, you can see the gas, and brake works on the meter, but gas doesn't actually move your car.
Plus,with mal-function in PS3 XMB, by automatical move up, or down continously..
To fix this,
First, switch the red wire around, now 2 to 4a, 4 to 2a...
Now you see the gas works perfectly in game, but no brake...
2nd, why the brake doesn't work?
Easy solution, just reverse the plugs on brake...
From *red wire, green wire, black wire* to the reverse direction on PCB : *black, green, red*....
Now the brake works in game...
Also this fixed the malfuction problem on XMB...
it doesn't keep going up or down automatically anymore...
I tried and test last night for 3 hours, almost gave up...
Hope this helps somebody..
