Spacers

Bosch EV14 injector sizes.jpg

2 1/2" (64mm) injectors require 12mm (7/16") spacers when using the S4 intake manifold and fuel rail. If you are using an RS4 fuel rail you will need a 1" spacer!

mm inches Bosch (not c-to-c) S4 rail spacer RS4 rail spacer
37mm 1 1/2" 33.60mm N/A none
52mm 2 1/16" 48.65mm none 15mm (9/16")
64mm 2 1/2" 60.65mm 12mm (7/16") 27mm (1")

Note that Bosch's EV14 length specs are not o-ring center to center


Adaptors

034 Motorsport adapter
Connector Shape Bosch A.K.A.
Jetronic Rectangle Design II EV1/Minitimer
USCAR Oval Design III EV6/EV14

Injectors are male, harness is female, so to use a USCAR/EV6/EV14 injector on a Minitimer/Jetronic/EV1 car, you need a USCAR (female) to Jetronic (male) adapter.[3][4]


Conversions

  • 1 lb/hr gasoline = 10.5 cc/min (@720 kg/m3) (1 (pound / hr)) / (720 (kg / (m^3)))
  • Density of typical test fluid = 760 - 770 kg/m3
    1 lb/hr = 9.81 - 9.95 cc/min
  • Density of n-heptane = 685 kg/m3
    1 lb/hr = 11.0 cc/min
  • 3 bar = 43.5 psi
  • 4 bar = 58.0 psi
  • 5 bar = 72.5 psi

Instrument cluster

If you change fuel injectors, your instrument cluster will estimate your fuel consumption incorrectly. Use VAG-COM to adjust it by going to Instrument cluster (17) -> Adaptation (10) -> Channel (03).[5]

Unfortunately, you can only set it to a maximum of 115%. Default is 100%.

If you have access to ME7.x tuning tools, you can completely fix cluster consumption by adjusting the KVB 1x1.
