Opel Zafira Z18XE Simtec 71.1 ECU Injector Pinout Diagram Inquiry

Welcome

I will be grateful for the diagram / pinout of the Simtec 71.1 ecu injectors.
The car is Opel Zafira 1.8 Z18XE 125 KM.
The ECU is starting to go crazy, everything points to cold February, a popular fault in these drivers.
Does any of you have such a driver damaged? I would love to train and test the fluxes before I start my own.

Regards and thank you in advance.

It's a hybrid, and not cold February, because it's a different technology.

On a well-known portal, you can easily buy a used one for little money.
Generally for the amount you can repair it.

There are ultrasonically "soldered" connections between the socket and the PCB - they are responsible for the fault. A used ECU is an expense of PLN 500 + replacement, reprogramming, etc. Of course, there is a risk that the "new" ECU will fail in a moment for the same reason or has the same defect that will reveal itself after some time. The new ECU costs about PLN 1,500, so I want to experiment and solder this invention.
There are fluxes for aluminum that I want to use.

And repair around 150-300 depends where.
Let me know after the repair, I'm curious

Gentlemen, I have given up soldering this, despite having a flux for aluminum and some practice, is not easy. The paths are additionally covered with a layer that needs to be sanded, so it remains to tear out all the wires, grind the paths and put new wires. Congratulations on what this patent came up with. Besides, the 50W soldering iron is too weak. The PCB of the ECU is thick and looks like "porcelain", it transfers heat to the aluminum casing very well, which makes it difficult to melt the tin with the kind of equipment I have.
