The car is currently running very uneven and rich. Did some spark testing and I have a strong suspicion the ignition system is not working as it should. When running an engine crank and cam shaft simulator called Ardustim the ECU looks to work as intended. Injection time has been calculated to be 12.7ms using one method and 12.2ms using a different formula, seeing as these are only about 5% apart from each other I cannot be too far off. Earlier in the project I have had issues with the wiring harness, this left me stranded at a gas station once as the starter actuator signal was missing. I believe the wiring was damaged when I removed or inserted the engine and transmission.

Hopefully there aren't too many more wiring issues, but we will see.
