Default F30 N55 EWG JB4 Question - 02-11-2021, 05:05 AM

Hey guys, I just got my first BMW back in December with plans on modfyingng it. From the title I have a 2015 335i. I have gotten all my bolt ons minus the intercooler which should be here soon. The question I have and haven't been able to find the answer to is if I can run map 5 on the jb4 if I don't have the fuel sensor plugged in? I'm not planning on running e85 for a bit so I didn't see the need to plug it in for now since it's optional. I'm running map 2 at the moment and it's great but I see people saying that map 5 is a lot smoother and has potential for more power. Sorry if this isn't the correct place to post this but I've seen you guys help other people out a lot on here so I thought I'd try too. Thanks in advance. routerlogin 192.168.l.l

You don't need the fuel sensor, even when running ethanol, though it is recommended. However, for running map 5, you are going to want to consider getting the EWG wires.
