Problem with Arduino LCD display

[Karseq]

Hello, I found a post from a few years ago where was uploaded the code for arduino, wiring diagram and the test movies on YouTube. I'm enjoed it but when i try to use this i encounter a one big issue. I have installed the X-Sim software and i upload code to Arduino but still display doesn't receive data from games. It still shows just words like: SPEED RPM and N (gear). I do everything in X-Sim like it was explained in post but i still don't know how to force the Arduino to show informations on display. I hope you will help me soon. I think that arduino doesn't receive data from Xtractor but I'm not sure
