Twin GTI Club Conversion [Help needed]
« on: December 29, 2017, 07:55:17 am »
TLDR: Logitech Driving Force EX (the PS2/PC blue one) wiring diagrams wanted. Thanks

Hi there,
Last December a group of friends and I bought a GTI Club twin cab. It wasnít the game I played the most back in the day, but we liked the looks and it was cheap enough. The seller didnít know if it was in working condition, but for the price we thought it was fair enough if only for the seats , control panels and wood.







Finally, after 2 weeks waiting , the cab was at my friends garage. We made a first round of cleaning and started to figure out all the wiring and components. The seller already pointed out there was a missing PCB and power supply



The original project: the restoration

We downloaded the ownerís manual and after several attemps, it passed the tests and the game boot correctly. You can imagine our excitement. We were expecting nothing in this regard but instead we got a working cab. Screen, sound, and controls work almost to perfection (Handbrake too!).




At this point we thought the best route was to get a second PCB and keep the cab with its original game. And try to repair the second CRT which showed no signal.
But turns out GTI Club wasnít a popular game in Spain (at least not like Sega Rally or Daytona) and it wasnít cheap to get a working PCB without costly (and risky) international shipment.
We found a very cheap board with unknown working condition and took the chance, but the PCB was dead.



But this wasnít the only bad news. Sadly, after a couple of parties at our friendís garage, the working CRT started to switch off by itself after shorter periods of use each time.  At one point, it wonít turn on anymore.
With this situation we sat and thought ďAre we going to spend more money trying to repair old components to stick to one game? Or can we try  to turn the cab into a multi-system emulation machine?Ē And we ended up going for the later.

The PC conversion

After a lot of reading in these forums, we decided to go for a PC Conversion:
  • Replace the 2 CRT with 2 flat panels
  • Use the Haap Wheel Hack using a couple of Logitech Driving Force EX pot wheels and a couple of AMC servo amplifiers.
  • Add buttons to control pc games, and rewire the original ones along with the sequential shifter
  • use a frontend to launch and quit the games without mouse and keyboard

The screens
We bought a couple of second hand 27Ē tvs that fit almost perfectly in the cab. The we built a mount using the original frame of the crts







The control panel
Right know weíre stucked wiring the wheel buttons. Wheel and pedals work perfectly (and force feedback!) but it seems we have some kind of short with the grounds of the X, Circle buttons and the directional pad. L1,L2, Start and the rest work fine.

Every post or tutorial we've found where there was a mention of the wiring diagram of the Driving Force EX has the images dead. So Iím asking if anyone has a copy of it (or at least an indication of the grounds used by the directional pad and main buttons)

Thank you in advance

Wow, thanks! Seems this is a different model because it has analog paddles (ours are digital). Anyway, I'll have a look at the pinout and see if the other buttons use the same.

I think I saved the original web page somewhere if this ever happened.
I will look for it later today or tomorrow.
