Ok so I finally got around to checking some things. When I pull (one of the) spark plugs after cranking it's not wet, but I can smell the petrol from the spark plug hole, so I figured the injectors are fine. Unless the engine is always emitting a petrol scent :P Don't know on how to test if the ignition works, since when I pull the fuel injector relay it also shuts off the MS itself so it doesn't even know when to spark.
What I did after that was: I made a new project, opened the tune for the 240cc injectors, which, because the firmwares do not match, gave me the warnings that are also attached in a TXT file.
And gave me an error message for conflicting boost pins, so I turned off boost control, which seemed to work fine.
After that I cranked the engine, still no start.
I started logging before I cranked so I'll attach the file to this post.
Fun fact, I can't use the detect function within TunerStudio, but if I manually choose the firmware and select the COM port it'll connect without any problem.
UPDATE: Okay I know the ignition works, I used the test feature in TunerStudio and I saw the spark. I'm still positive the car gets fuel as well, since both the cylinder and the exhaust smell like petrol after cranking. The map especially for the 240cc injectors still only cranks, the same goes for the MSPNP map from diyautotune.com. The ecu doesn't seem to get an RPM signal while cranking, which might be what's messing with starting. Apart from that it constantly has a TPS signal of around 40-50%, but I don't know if that's messing with anything. Also, is there a difference between the top (bigger) holes on the connector board and the lower (smaller) holes?
I also attached two logs and the tune with the MSPNP basemap.
UPDATE 2: I'm pretty sure the car doesn't start because of the fact it doesn't get an RPM signal. Whenever I crank there's no difference in the RPM, which is also visible in the logs. Is there any place on the board I can double check that's related to the RPM signal, as I'm getting sad by not being able to drive my car :P
I took some pictures of my mainboard, tried the 51K ohm resistor both on R20 and R21 and without it, but no luck.
Any help would be greatly appreciated!
There's a wire going from TPS to GND on the mainboard with a 1k Ohm resistor in between, saw the resistor between 4L and 4D in another thread but since 4D is already occupied I solved it like this. The TPS is now stuck on 0% so that's good.
UPDATE 3: Uploaded some logs and the tune I'm running now, which seem to not start a little better than the previous one xD
