用于电子燃油喷射升级的双曲轴和凸轮轴位置传感器。保时捷 911 1974 年至 1983 年
带皮带轮的双传感器套件是完整的发动机位置监控套件

适合：
保时捷 911 / 911S - 1974 年至 1977 年
保时捷 911 3.0ltr Carrera - 1976 年至 1977 年
保时捷 911 SC - 1978 年至 1983 年
保时捷 911 Turbo - 1975 年至 1989 年
适用于配备 CIS / K-Jetronic 燃油喷射的汽车

双传感器单元，无滑轮，适合那些可能从另一个曲柄传感器套件升级并安装了触发器的人。只要触发轮直径在 127 毫米到 132 毫米之间，那么我们的套件很可能可以与现有的触发轮一起使用。

双传感器
每 720 度触发一次（压缩冲程）
36齿触发轮

双传感器– 该装置具有与单传感器相同的传感器，但第二个传感器指向安装在 Adapt Motorsport 曲柄皮带轮上的触发盘。标准情况下，这是一个 36-1 滑轮，这意味着它有 36 个齿，减去 1 个缺失齿。这使得 ECU 能够始终了解曲轴位置，并结合内部传感器，无论是在 720 度循环中的压缩冲程还是排气冲程。该系统提供了完整的发动机位置传感套件。如果您现有 36t 触发盘，则可以在其上使用我们的传感器套件，前提是齿是为霍尔传感器而不是磁传感器设计的，并且齿的外径在 127 和

130毫米。请联系我们进行澄清

为什么需要该系统以及什么是曲轴/凸轮轴位置传感器？

将经典保时捷改装为现代电子燃油喷射时，发动机控制单元 (ECU) 需要准确了解四冲程循环中曲轴和凸轮轴的位置以及它们的旋转速度。这使得 ECU 能够正确计时每次火花和喷油器打开时间和持续时间。第一个传感器指向曲轴皮带轮并测量每个齿的脉冲。有一个缺失的齿，ECU 可以据此计算出曲轴相对于该缺失齿的位置。脉冲之间的时间给出了发动机的速度和变化率。

但有一个问题，发动机旋转两整圈才能完成其四冲程循环。因此，虽然使用这一传感器，ECU 知道它相对于上止点 (TDC) 的位置，但它不知道它是处于压缩冲程还是排气冲程。这就是第二个参考传感器的用武之地。该传感器安装在我们模块的主体中，并测量单个牙齿。由于它安装在分配器孔中，因此适合以发动机一半的速度运行，因此每 720 度会产生一次脉冲。通过这两个传感器，ECU 可以知道发动机在四冲程循环中的确切位置。现在，我们可以进行精确的顺序喷射和点火。

我们的套件使用高速数字霍尔效应传感器向发动机控制单元提供数字输出，这些传感器最好在 8V 下运行，大多数现代 ECU 都有专用于曲轴传感器的 8V 输出。

机加工铝制外壳和阳极氧化表面处理，配有免维护青铜衬套和终身密封滚柱轴承。这些传感器具有相当大的可调性，因此通常能够与其他优质供应商提供的现有曲柄滑轮和扳机轮设置一起使用。

Sync 2 套件包括：
主体组装
ZF 霍尔效应传感器 x 2
接线和连接器，带有用于连接到接线器的引脚和连接器。

与其他曲柄扳机系统一起使用。
（我们不能保证该系统适合每个曲柄/扳机系统，但可以轻松修改以适合大多数系统）

该更换套件使用您自己的工厂分销商装备适合OEM 分销商位置。只需从安装齿轮中拆下工厂分配器齿轮，连接到 ECU，微调曲柄触发盘的传感器气隙，在 ECU 中设置参考位置，您就可以获得最新顺序燃油和所需的所有传感功能。点火系统。该套件适用于 2.7lre、3.0ltr 和涡轮分配器齿轮。

2.7 发动机可能需要修整曲轴箱靠近曲轴皮带轮的部分，以防止干涉。

This kit is a modern update to the 911 3.2 ignition system and brings the management of the car into the digital age to allow greater control over ignition and fueling.

The kit replaces your restrictive old fashioned air flow meter (barn door) with a modern map sensor managed by intake pressures.

The kit gives many driving benefits, better/smoother power delivery, better throttle response, eliminates lots of the low-down idle problems as it now uses a throttle position sensor and delivers more torque and BHP.

The kit is delivered ready to use with a PPT ignition map for the 3.2 standard engine management; however, the kit can be mapped for different cams and engine capacity increase.

Our latest kit now comes with an upgraded ECU and can run a wide band sensor (oxygen sensor).
Our kits include this capability but the sensor needs to be ordered separately.

While developing the upgraded ECU we have also changed our intake pipe; this now works with the factory airbox, gives a stock appearance in the engine bay and houses the map sensor and air temp sensor out of sight.

Kits includes:
• Delta 700 ECU
• 2 x Direct plug-in wiring looms
• Map Sensor and air temp sensor
• Air intake pipe, gasket, and bolts
• 6 Bosch injectors
• Vacuum pipe and T connector
• Throttle Position Sensor (TPS) and adaptor
• Support and service by PIE Performance
• Can Bus data connection tool

All our kits are 100% reversible, with no need to drill or alter components, we utilise what already exists

Patented technology that helps to increase air flow dramatically thus minimising air flow separation and reduces turbulence, resulting in higher volumetric efficiency.

This pristine technology with Knife-edged butterflies has improved inlet airflow and performance significantly. With the individual Throttle blades very close to the inlet valves, the engine and Throttle response are vastly improved. Along with this, we have also found an impressive increase in Horsepower, Torque, Driveability, and an incredible mechanical soundtrack.

Throttle Bodies come fully assembled and ready to bolt directly to the Cylinder Heads, with the following parts included:

• Anodised Aerospace Grade 6082/T6 Billet Aluminium "Shaft-less" Individual Throttle Bodies.
• Anodised Aluminium Inlets/Extensions suitable for flatdeck & ducktail models.
• Aluminium Ram Pipes & Assembly Tool.
• Throttle Position Sensor (TPS).
• Billet Aluminium Fuel Rails, Including PICO 377cc Fuel Injectors.
• Thermal Insulation Gaskets.
• Throttle Linkage System which connects directly to the existing OEM cable pick-ups.

These adapters are used to modify the 2.7ltr / 3.0ltr / 3.2ltr Porsche 911 2 bolt cylinder head engines to the later 964 / 993 3.6ltr intake manifolds when converting to EFI.  

CNC machined on a 5 axis machine to our exacting tolerances and finish and anodised dark grey these are custom machined to match your port diameter and tapered to fit up to the 42mm inlet manifold port size.

The short adapor height maintains the overall height of the intake set, reducing the interference between the idle air control, the intake boot and the top of the engine bay insulation.  The factory plastic 3 bolt 964 stacks are too tall, and adding an adapter spacer would make the manifolds not fit at all.

This design permits the use of the standard 964 fuel injectors and fuel rails so positions the injector over the same relief in the intake port for the original CIS injector, ensuring proper atomisation of the injector spray into the intake port.

Key Features:
Precision machined from high grade aluminium
Anodized finish

Notes
Tested to 10,000 RPM

Increasing the performance of an engine via the crankshaft does not make sense at first glance, but it is worth taking a closer look. 

The mechanical efficiency of an engine, which, together with the thermodynamic efficiency and the volumetric efficiency, determines the rated output of an engine, depends fundamentally on the diameter of the crankshaft bearings and the friction in the bearings. 

Of course, the diameter cannot be easily changed, but the friction can, which in turn depends on the bending loads and the resulting vibrations of the crankshaft. This is exactly why the use of top-quality titanium connecting rods is of little use if the resulting significantly reduced rotating masses at the connecting rod foot are not also taken into account on the counterweight side of the crankshaft. 

Because only a perfectly designed crankshaft, calculated for the connecting rod weights, actually brings with it less bearing friction due to eliminated vibrations, and thus an increase in performance. Furthermore, this crankshaft is speed-resistant up to 11,000 rpm and tested in continuous operation up to 10,000 rpm. A pleasant side effect is of course a reduced load on the crankcase and less wear. 

This crankshaft is designed utilising the latest calculation methods using CAD and FE methods (finite elements) and is designed for operation with titanium connecting rods only.

If you want to run this crankshaft with steel connecting rods, use crankshaft part number 90110201100/1. Failure to comply with the mass balance will sooner or later lead to the crankshaft breaking at maximum speeds. 

Furthermore, this crankshaft is an authentic replacement for every standard crankshaft of the 911 from 1965 to 1971, i.e. every 2.0ltr and 2.2ltr engine. 

You can easily swap out any 2.0ltr or 2.2ltr 911T crankshaft that doesn't have factory counterweights for this crankshaft with counterweights.
