Picked this JB4 PWG from a F10 520i owner. I have a few questions which I hope someone could help with:

1. Will this work on my F30 328i N20 with EWG?
2. Can this use the latest firmware? If yes, which one should I flash to? N20_OBDII_PWG_6.hex or N20_OBDII_EWG_6.hex?
3. Can this work with the latest revision of the JB4 connect kit?
4. The harness comes with 4 pairs of connector: rainbow, brown, black and blue. I know for EWG I can skip the blue connectors. How about the black wire connectors?
5. The harness also comes with a ground cable (and I think also a red power cable). Do I need to hook them up? If yes, I assume black to shock tower nut and red to +ve terminal?
6. Anything else I need to make it work?

Im getting conflicting responses - some say it'll work for EWG up to map 2 while others say it wont work.

Attached is a picture my JB4 for reference.


Sorry for all these questions.

make sure you it is a EWG jb4 or else it will not work since you have a EWG

bluetooth connect kit should work if hooked up right

download the ewg hex files

for installations

Getting more and more confused with conflicting responds. Some say it'll work up to Map2 on EWG while some say it wouldnt work.

if everything is all good you can run all the maps if you want but if your just full bolt ons map 2 is your best option. The other maps require meth or e85 which you probably wont use

Thanks for the feedback. No plans to run beyond map 2 so hopefully its all good.

Anyone tried flashing EWG firmware on a PWG board?
