029 | How to Tune the Fuel Charge Cooling Coefficient in a Link G4+

Summary

If you are planning to use the ‘Modelled’ fuel equation in the Link G4+ or Vipec i-Series ECUs running firmware 5.2.2 or later, one of the first tasks once you hit the dyno is to calibrate the ‘Fuel Charge Cooling Coefficient’. This defines how much the fuel being injected will cool the intake charge and has a significant effect on how accurately the ECU can track requested changes in air fuel ratio. In this webinar we will look at the correct approach for tuning this parameter using our Nissan 350Z fitted with a Link G4+ ECU.
