All you need to do to make this run with 1.337 is to change the ID of the engine block in the config... It amazes me that people know how to post detailed bug reports with logs but can't catch the big warning in ModLoader.txt that clearly states
"ID 219 already assigned to BCIC2 crossover engine@luminator" <--- Not exactly that but to my best recollection. Took me 10 seconds to find and another 20 to fix in the BCIC2 crossover config file.
