Video: How to set up fuel injection jetting in a ProCalc calculator A baseline is the default jetting setup. It is the starting point for tuning for air density changes at a subsequent race. It may also be the starting point for a new FI setup. ProCalc provides an easily retrievable record for precise numerical […]
Combustion is between oxygen and fuel. The ratio of the two determines whether a mixture is best horsepower, best torque, rich, moderate, or lean. Air to fuel ratio (AFR), the basis for tuning with ProCalc, combines the weight of the air and the weight of the fuel. The air is only 23% oxygen by weight. […]
