Engine ECU File Locations?

I'm working on creating an engine swap mod, and my biggest issue atm is finding the ecu's for the engines already in-game, specifically for the Roamer, D-series, and H-series. I want to copy and modify them to work with the engine I will be making, using custom values within the ecu, but I cannot find any jbeam files for them. I know the ecus in those vehicles will still carry over to the modded engine if written properly in the engine jbeam, but I want to go further with that. I could try making ecu files from scratch, but I've got little experience with writing jbeam files.

Any help or information is greatly appreciated.

 

The engine/ecu jbeam for the Roamer, D-series and H-series is in common folder. vehicles/common/pickup/

 

from what i can tell, the engine jbeam only defines the default ecu that the engine spawns with. The jbeam also references the ecu options, but does not actually allow you to modify them, as none of the ecu values are shown. It indicates that there is a file separate from the engine jbeam that handles the ecu. I've seen this is some of the mods, but i cannot find this in the pickup or related vehicles. If the ecu parameters are indeed in the engine jbeam, would you mind posting a screenshot showing me approximately where in the file it is written?

 

Not on my pc, wait

@NinjaGoatX The ecu of engines are in the engine file after the codes of engines, for example, the ecu for the v8 engines is in the line 1083 in the v8 engines jbeam.
Btw, if you have winrar, if you copy the jbeams and paste them in another folder, they will be extracted. So you can open them, delete all codes except ecu codes, edit the ecu files (rename them and change the values)
Look at these:

 

Thank you, I think I found my issue... I was using the diesel engine as a base jbeam for the mod, and that was why there were no ecu scripting... lol

Also, would you know how I would add an ecu from another engine into the jbeam? I assume it would require a json file similar to how custom sounds work, but I cannot find out what file tells the game where to search for the new ecu (looking to simply add a sport or late ecu to the diesel-based jbeam file).

 

You can add any ECU to any engine. ECUs are just some codes that they change the engine's max rpm and sometimes some limiters like rpm drop shot. As Agent_Y said, the only thing you need to learn is the slot type system. Now look at the ECUs for the v8 engine, the slot type is "pickup_engine_v8_ecu". It means the ECU only shows on gasoline v8 engines. If you want to add it to a diesel engine, open the diesel engine jbeam and look at the slots paragraph. One of those slots is the diesel engine's ECU. Copy its name. Go to ECU jbeam and paste the copied text in the slot type. Then, it will show in the diesel engine's ECU slot.

 

I thought about that, but I cannot find any ecu configs in the diesel v8 jbeam. I know its not the same as the ecu as the gas v8, but I cannot find where it is.

Edit: I is the dumb. I was using the van diesel engine jbeam which piggiebacks off the pickup's jbeam, hence why I couldn't find the ecu. *facepalm*
