Kjet designed with performance in mind
Digifart designed with economy in mind
You are wrong.
K-jet - designed to improve on a carb
Digifant - designed to improve on earlier injection systems like K-Jet.
Digi 3.2 will give you the most reliable, powerful and economic solution vs K-Jet. Why? Because it controls the systems on the motor in a more advanced and closed-loop manner. A couple of examples:
Knock-control - two sensors, which will allow you to advance the spark more to get more power if you have better fuel
Lambda, MAP sensor and throttle-position-sensor - measures the burnt mixture, allowing the vehicle to manage the amount of fuel going in, to suit WOT applications, cruising and start up etc etc
The K-jet has a shaped bowl and a flap, which controls the amount of fuel misted and a warm up switch to enrich the mixture.
It is primitive and prone to failure.
Solid state components last much longer and are more reliable. They can also respond faster.
Trying to suggest that the injection system fitted to the G3 16V GTI is 'for economy' is a stupid suggestion.
A properly built and managed high performance motor should be high economy too when it's not being thrashed. That's what EFI allows you to do.
