Need help for engine tuning!

Hey everyone, so here is the problem I am having today. I made a new engine for the ETK K and 800. As you know, the engines are shared. Long story short, I simply copied one of the ETK i6 engines, pasted it at the bottom of the jbeam, renamed the engine, and tweaked the settings. Everything works fine, but the problem is that the engine is now a default engine for the base models. I only use one variant of it, so I don't know if it is default for EVERY variant. I was wondering how I can change this to make it so that the engine is only accessible as an option? Here is the first part of the jbeam for the new engine.
"etk_engine_i6": {
"information":{
"authors":"BeamNG",
"name":"6.5L V12 Engine",
"value":16000,
},

As you can see, I simply changed the name and the value. Any help is appreciated. Thanks!

 

Change the bit that says "etk_engine_I6" to whatever u want, like put your name in it, this makes it separate to the stock engines

 

Thanks man.
