==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).<ref>http://forums.audiworld.com/performance/msgs/30668.phtml</ref> |
|||
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 [[Tuning | '''KVB''']] 1x1. |
|||
<math>TKVAG = \frac{\sum_{t=0}^{TMAIN} (rk_w+rkte_w) \times KRKTE [ms] \times KVB [cm^3/min] \times 1000}{Kd [mm^3/s] \times 0.0512 [ms] \times 60000}</math> |

- Bold denotes the rated flow/pressure.
- Length is o-ring center to center.
Pattern/Orientation
- Cone angle - Bosch:
- 'α80' for single cone (how much angle contains 80% of mass).
- 'α50' for dual cone (how much angle contains 50% of mass in both cones)
- Pattern angle for dual cone - Bosch 'β' (how much angle of one of the cones contains 70% of its individual mass)
- Orientation angle - Bosch 'δ'
- Bend angle - Bosch 'γ'
Stock injectors are dual cone with 270° δ and have non-zero γ (S4 is 0° γ?)
- Injectors with 90° δ or 270° δ must be clocked with their connectors perpendicular to the block, such that the dual cone is parallel with the block.
- Injectors with 0° δ or 180° δ must be clocked with their connectors parallel to the block, not perpendicular, such that the dual cone is parallel with the block.
- Injectors with non-zero γ must be oriented so their "bend" is oriented into the heads properly.
- Injectors with non-zero γ and a 90° δ cannot be physically clocked correctly, since the physical connector prevents the injector from being clocked such that the bend points in the correct direction.
Note that many 0 280 158 117 injectors modified for greater flow ARE NO LONGER DUAL CONE! Verify before installing.
Spacers
2 1/2" (64mm) injectors require 12mm (7/16") rail spacers when using the S4 intake manifold and fuel rail. If you are using an RS4 fuel rail you will need a 1" spacer! 1 1/2" (37mm) injectors require 15mm (9/16") injector spacers with the S4 fuel rail.

| 64mm | 2 1/2" | 60.65mm | N/A | 12mm (7/16") | 27mm (1") |

Adaptors

|---|---|---|---|
| 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.[1][2]
Conversions
lb/hr to cc/min
- 1 lb/hr gasoline = 10.5 cc/min (@720 kg/m3) - (1 (pound / hr)) / (720 (kg / (m^3)) )
- 1 g/min gasoline = 1.39 cc/min (@720 kg/m3) - (1 g/min / 720 kg/m^3 ) in cc/minute=)
Flow dependency on pressure
- 3 bar = 43.5 psi
- 4 bar = 58.0 psi
- 5 bar = 72.5 psi
- RC Engineering's online calculator
Common test fluids
- 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
- 1 g/min = 1.46 cc/min
- 1 cc/min = 0.685 g/min
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).[3]
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.
