JB4 Identification

SliderMSG · 07-16-2018, 03:04 AM

Hi, I just bought a used JB4 for my 2011 335i N55 (Harness A) and now that I am taking a closer look at it and doing some research it looks like it is for a F30 N55. The board has the following printed on it "JB4_PWG Rev 4" can anyone tell me if this is the right board for my car or did I get burned?

Thanks in advance.

It should be the correct one for E90

From what i know all F30's use EWG (Electronic Wastegate) and if it states PWG that means its a Pneumatic Wastegate, which the E90 uses.
The only thing now is to check if you need harness type A or type B. There is a link on BMS website that shows you how to easily identify it.

Thank you for info, I also have an email into Burger to see what they say and will post what I find out.

Rev4 is the newest revision. Not all F series are EWG, 2013's are PWG.

SliderMSG, I think you lucked out; that should have port injection control built in along with a better power supply.

Thanks for the info! I am going to install it a week or so and I will post what happened. Ando from BMS got back to me via email and let me know it should work with no issues as well. Thanks again for the help !
