Great app, except it's not working when I drive the Ginetta G55 GT4 2017 V1.3 (found here)...Grass/dirt buildup and tyre lockup seems to work but tyre temps, pressures and wear/lifespan isn't working. I tested it with other cars and it works fine.
Make sure you have install the ini&lut files for this car found here:
