Known bugs due to be addressed soon!
- Apparently some HS8's use a 0.1" jet. WinSU only allows 0.125" jet for 2" carbs. Maybe WinSU needs to allow separate jet and carb type selection?
- WinSU needs a "Not applicable" item in the list for Rocker selection for overhead cam engines
- Morris Minor weight needs reducing to approx 750kg
- Swiftune cams need adding. Maybe split cam selection into manufacturer and model, with an alternative manual input of duration, lobe angle etc
- Compression Ratio needs adding
