  • Change Fuel Composition Boost Limit to be applied multiplicatively on top of other boost limits. This allows other boost limits not to be overridden when running on the limited fuel. ***May require some retuning of boost limits.
  • Add Coolant Temp Head and Inlet sensor inputs. Head can be used for coolant temp if greater then coolant temp. Inlet is for logging only.
  • Add Inlet Cam Diagnostic, reporting aim tracking errors. This also encompasses the cam sensor warnings which have otherwise been removed.
