Soooo. Story time. I was installing a billet intake manifold chasing a low boost issue after replacing all the charge piping and putting a 1k Mad intercooler on the car when I didnt get one of the DME plugs all the way connected. I started the car and it ran like it was only on a couple cylinders. I plugged my phone in and mhd couldnt talk to the dme. It has worked fine in the past. Next I plugged the laptop in and opened itsa. Itsa cant talk to any of the modules. I check all the fuses then replace the JBE. That didnt fix it. I then bought a known good used DME. I got that installed and nothing changed. Same issue. I bought a new battery, same thing. So now I cant talk to anything and will need to code the JBE,DME and new battery. I did try teh gambit of BMW software to make sure it wasnt an itsa problem and none of it would find anything. INPA wouldnt even show the ignition as being on. It would find the cable though. Is there a BMW mechanic in Oregon that someone would suggest I take this too? I build Hondas and DSM's but this has officially kicked my ass and I want help. Im not asking for free labor, I have no issue paying to get it fixed I just cant find the problem at this point.
Thank you for taking the time to read this.
