Description

The MD35 ECU is a programmable engine management system that can be used as an independent Engine Control Unit (ECU) for virtually all types of gasoline engines, or in combination with a standard engine management system.

This system is equipped with a 38 channel data logging feature to enable professional style development of your vehicle. 

The MD35 can take over the standard injection/ignition at any desired engine speed, boost pressure or throttle valve position.

The MA5 works with all KMS accessories & components. Activate for instance one of the key features, a complete self-learning air to fuel ratio control (lambda control) with the KMS Uego CAN controller set to. Precise ignition and air/fuel mixture control will lead to excellent drivability, performance and low fuel consumption.

Fuel injection throttle body kit with air horns - Without fuel injectors



Fits:
Porsche 911 2.0ltr - 1965 to 1968
Porsche 911 2.2ltr - 1969 to 1971

Sizes Porsche 911 intake manifolds
Carburetor/Bosch MFI Ø32mm engine side - Ø40mm ITB side. Recommended for early 2.0ltr / 2.2ltr engines

Injectors options that can be used - 260cc / 300cc / 380cc / 420cc / 480cc / 520cc

This is a direct replacement kit for replacing carburetors while keeping the OEM look in your engine bay. 

The intake manifolds and riser plates are manufactured out of a single piece of 6082 aluminum and come in 2 styles. These differ in design due to the shape of the mounting flange for the cylinder head. The intake manifold can be used as replacement parts for the OEM part when damaged or has to be replaced*.
The ITBs are manufactured out of cast aluminum, whist the fuel rails are made out of aluminum 6060 extrusion profile and come with AN6 ORB connection for the fuel lines. The direct mount fuel pressure regulator is directly mounted to the fuel rails, so in this case you don’t need to drill additional holes in the engine bay for mounting a fuel pressure regulator.
The throttle linkage and all mounting hardware is made from stainless steel and the pivoting point of the throttle linkage is a ball and socket design for smooth operation. The levers allow you to adjust and finetune mechanical movement of the ITBs

The dimensions of the assembly are the same as the OEM carburetor setup and the riser plate comes with same mounting holes as the OEM carburetors, in this way you are able to use the OEM air filter box and OEM airhorns. Also the riser plates come with mounting options for an air intake temperature sensor, this is nicely hidden away between the ITBs. The diameter for the ITBs in the riser plate is 45mm. There is also an option for using airhorns, In this case you don’t need the riser plates.

The crank sensor and trigger wheel kit are additional and this type of kit is needed when using ITBs like these. Besides switching to ITBs you will need a stand alone ECU to get the fuel injection to work. Our kit only works with engines like the 3.0ltr that came with a “ big distributor”. You can leave the distributor or you can remove this unit when you are going to use a discoil type of ignition. In for case an adapter is included in the crank sensor kit. The pulley comes in 2 dimensions to choose from, a Ø116mm pulley and Ø126,5mm pulley.

Fuel injectors, fuel lines, standalone ECU, wiring harness are NOT included in the kit.

*In case of using as a replacement part 3 mounting holes for the carburetors or ITBs need to be re thread with a timesert or helicoil. Otherwise it is impossible to mount a threaded stud.

Kit Includes
2 x Full billet, hard anodised intake manifolds
6 x ITB complete with lever assembly
6 x Airhorns 45mmØx30mm
2 x Fuel rail with mounting hardware
1 x Throttle linkage with 2 throttle connection rods
1 x Direct mount fuel pressure regulator
2 x Riser plates with 1 air temperature sensor (for use with OEM air filter box)
1 x Crank sensor and trigger wheel kit (optional)
All needed gaskets and mounting hardware.
