VW Fuel Injection: Convert your aircooled VW
What is fuel injection?
Electronic fuel injection (EFI) is an improved system of
delivering the fuel (and ignition) to your engine. The carburettor(s) that is factory fitted
works on the principle of vacuum to draw a metered amount of fuel into the engine.
EFI replaces this with an electronic system that precisely measures the engine speed, angle, load
and temperatures. It then uses this data to calculate the required volume of fuel needed for each engine
cycle, and injects it electronically as a highly atomised mist for efficient combustion.
The Engine Control Unit (ECU) can also be programmed to fire the spark at the optimal time
under all conditions for maximum engine efficiency. This is programmed with our in house
VW Dyno Tuning.
How does fuel injection benefit my aircooled VW?
There are numerous benefits to converting your aircooled VW to EFI. These include, but are
not limited to:
- Increased power
- Increased low end torque
- Improved throttle response
- Improved fuel economy
- Improved drivability
- Perfect cold starting
- Smoother running engine
- Engine does not go out of tune between services
- ECU learning (tune is refined as you drive)
- Flex fuel tuning (Petrol and E85 compatibility for even more power)
- Boost control (turbocharged cars)
- Increased engine safety in hot weather
- Customisable engine limits
- Engine protection
Fuel injection is a great upgrade over carburettors for your classic VW. The tunability of the ECU means there are
no longer any compromises with the fuel or ignition delivery. The engine can now be
perfectly optimised under all running conditions, leading to an increase in power and reduction
in fuel consumption at the same time. We have converted both VW Beetle engines (Type 1)
and VW Kombi engines (Type 4) to fuel injection with amazing results!
The additional engine protections, limitations and customisable tuning provide peace of mind that
your VW aircooled engine is being looked after.
