Or 2) install was done incorrectly and then problems arise because consumers want to purchase it and then not put in the work to data log and make corrections. I would say the JB4 is the perfect tune for those who want a more user adjustable configuration and the ability to increase aggressiveness at their own will. Some of us want to push the envelope a bit and see what these cars can truly handle others want a simple tune and leave it. Without that end user adjustability the n54 would have never been able to acheive 800+ whp.. I have been a JB4 user for years going back to my e92 335 and I also install a ton of them for customers and perform BMS backend flashing on the n54 and there is a reason they hold almost all records.

OP if you need assistance I'd suggest using BMS' support forum or emailing their tech support department. The EWG wires need to be routed away from the manifold. I've not heard of wires melting before I read this thread so I haven't paid close attention to that routing but if you post photos on BMS' forum I'm sure they can help you out.
Alternatively the JB4 is the only tuner that offers EWG control. You could not run the EWG wires and not have to worry about their placement and all that extra horsepower.
