Thank you for enjoying my mod. Sorry for a multiple months late response (I've been busy in my personal life). I have posted an update for my mod so you should see it appear soon after it gets moderator approval.
After i download this mod and go into the game and enter the garage, if i load a car then then screen doesn't load the car and shoots the in game vehicle in the air and doesn't load anything else out.
I haven't experienced this issue and haven't been able to replicate the problem, so I don't think there's much I can do to help. Maybe try clearing BeamNG's cache data or verifying file integrity (click Support Tools on the launcher). If you still have issues, you can DM me with more information.
I think this is a duplicate request. I found an entry already in my notes for this same engine from your username, which is fine; I just can't remember if I first saw it from this repository or the BeamNG repository. Anyways, it will eventually be added to the mod. You can see what position you are in for the waitlist if you open the spoiler under the Future Engines/Plans section.
Currently, Automation doesn't have diesel engines within their game, but once they support them, I plan to add all diesel engines manufactured by Ford. Since the Ford 8000 is a tractor, there's not really a vehicle in BeamNG I could add its engine to or make a similar configuration of (unless you want to DM me what your ideas are). For the Ford L9000, I could add it to the Gavril T-Series, but it used either a Cummins or Caterpillar diesel engine which Ford does not manufacture (however, I will make an exception since it was officially used in a Ford vehicle). I also want to mention that it is more difficult to find detailed specs of commercial vehicles, so when I make it I won't be able to guarantee 100% accuracy.
Love the mod, but my only complaint is that I think the engines are too quiet now. As you stated before they were way louder than other beamng engines, but now I think they are way quieter... is there a happy medium by chance?
When I reduced the volume of the engine sounds, I tried basing them off the volume of the BeamNG engines with default parts/mufflers vs something with race parts/no mufflers since most of my configurations are from street-legal production vehicles. The unit BeamNG uses for the variable of engine sound in their .jbeam is in decibels and not a 0-100% value. Due to differences per engine per vehicle, I would have to fine-tune each engine individually, which is a time-consuming process for the number of engines in my mod. I will see what I can do to improve it.
I would like to make them, but unfortunately, Automation currently doesn't support diesel engines so I can't make those engines as of now. Once Automations supports it, I plan to add all the Powerstroke engines and other diesel engines made by Ford.
I can add the 4.9L Inline 6 to the list of requested engines. You won't find any diesel engines in this mod because Automation doesn't support diesel engines. I will make sure to add the 7.3L IDI diesel when they do support it.
