Hi MaD_King, Thanks for the comprehensive answer, I will be giving this a go today. Such powerful software with so little centralised documentation ! Without you guys helping it would not be possible
Ok, seems to be working now. 1. Load track in game 2. Go to ~MASTEMP and copy track files to temp folder 3. Make changes in RFM file. NormalPitKPH = 100 FormationSpeedKPH = 200 Practice1Day = Friday 4. Repack RFMOD using updated RFM file (as explained by Mad_King above). 5. Race ! Thanks for the help guys !
