Hi, i really love how you are supporting the project, unfortunately the english guide is really hard to understand and i think that it misses some important things.
If you want, i have remade it and i think that this could be helpful for non-RU buyers.
Let me know if this sounds good to you :)
As soon as i can, i'd like to do a nice PDF with new photos but i need some time
improvement proposal for EN M102 Guide

Injector Rail
First, remove the air filter, then procede to remove the mechanical injector and the fuel distributor.
To install the injectors, insert them in the new fuel rail, then proceed to bend the two metal brackets of the rail and drill an hole on each bracket to insert the screw that will hold it to the intake manifold.
Before drilling, take the correct measurements and double check that the injectors are fully inserted in their housings.
Ensure to ermetically seal the start injector housing with a metal plate and RTV Silicone gasket. (Arexons Motorblack is reccomended)
You can also use a rubber tube with the external diameter of the start injector housing and then bolt a screw onto it to ermetically seal it.
Double check the EGR pipings. If any air leaks from the circuit, you will have issue with the idle.
Fuel lines and filter
Now it's time to install the new fuel lines.
The metal cylinder with three fittings is a fuel filter combined with a pressure regulator, you will need to get rid of the old original one.
The delivery line that goes from the fuel pump is connected to the "IN" fitting.
The return line that goes back to the tank is connected directly to the unnamed central fitting.
The main line that goes to the fuel rail is connected to the "OUT".
Use the the three black junctions provided with the kit to connect the rubber line to the filter/pressure regulator and ensure that they are properly mounted.
After the fuel line are installed, turn on and off the ignition (without powering the starter motor) 5-6 time to build pressure in the fuel line.
Check carefully for any leaks.
Idle Valve
The idle valve is left in the stock position.
Before installing it, clean it internally with throttle body cleaner and lubricate it with oil. Don't use WD40 as it is not a lubricant.
MAP Sensor
MAP sensor location is really important to ensure a great engine operation.
Locate MAP sensor exactly as show in photo.
Drill a 13mm holefor the sensor and an 8mm hole for the bolt that will secure it.
Cover the drill tip with grease to catch the debris, it is reccomended to clean the intake manifold after drilling the hole to ensure that no metal debris is left in it.
Use only a self-blocking dice to prevent it from detaching and damaging the engine.
Never install any sensor with the wires upwards, water will flow off the cable and shortcircuit the sensor.
ECU and wiring
ECU is dust and splashproof. It cannot withstand continuous water contact or pressurized water so it is reccomended to install it in a dry and safe place. Do not install ECU with cable upwards. In this case, water and moisture will flow off the cable into ECU.
Wiring harness for 4 and 6 cyl engines are unified. On a 4cyl engine you will have 2 extra injector connectors - those are closer to the ECU connector. You can cut those connectors or leave unconnected.
The best spot to install the ECU is next to the stock unit. Pull required wires from the harness.
All wires should be connected in parallel to the original ones, otherwise it will be explicitly mentioned.
