FS: F30 JB4 Stage 2 - Harness B - e85 Wires - USB - Circuit Pictured shows JB4 Stg2
JB4 with Harness B, e85 wires and USB (not pictured). I cleaned up the harness prior to installing. Everything is in working order and is ready to go. I will even include new posi-taps. $375 shipped OBO.  JB4 Stage 2 from their website:  Actual circuit board showing JB4 Stage 2  Updated with JB4 Stage 2 photo from burgertuning website. To reiterate, I added e85 wires so you can run an e85 blend with the proper maps. I used Map 2 and it was a smooth running tune with decent amount of power. I am including the Serial - USB adapter I purchased directly from burgertuning. Price lowered to $375 OBO! Last edited by posite; 01-25-2015 at 01:49 PM.. Reason: price |

It is a f30 Jb4 stage 2. I purchased it from extreme powerhouse here on the forum and the e85 wires and usb directly from burger tuning. Ran Map 2 and Map 5 and the JB4 had the latest firmware (as of 2-3 months ago).

How do you tell if your car has the pneumatic or ewg? I have stage 1 currently and I'm interested in upgrading but apparently you can't buy the jb4 in CA anymore!
 This will work with a January 2013 build f30 n55? I thought the jb4 was larger also. Is this smoother than stage 1? That was one of my complaints about stage 1, it seems like it was really finicky, sometimes it pulls hard and other times it feels slower than stock. |

Never ran stage 1. This was ok and with the e85 wires felt closer to my fbo n54 than I thought it would. Not sure on the cut off time from pneumatic to electronic. This is definitely a JB4. Maybe it is the e series JB4 everyone is confusing this with regarding size of the unit.

Updated with JB4 Stage 2 photo from burgertuning website. To reiterate, I added e85 wires so you can run an e85 blend with the proper maps.

I'm pretty sure that's stage 1, which is much cheaper.
Here's a photo of N55 Stage 1 - $379.00 new (pulled from Burgertuning.com) (looks like yours):  And here's a photo of F Series N55 JB4 - $529.00 new (pulled from Burgertuning.com):  So either you're mistaken, BurgerTuning is mistaken, or you are trying to rip someone off. No accusing any of which, but trying to clarify why everyone is saying you are not selling Stage 2. Also, you didn't pull that image from burgertuning, or else you would have copied the image URL as I did. You uploaded that image and I tried to reverse image search it and it didn't come up on their site, so you created that image.
