You'd have to email me to test the PWG OBDII N20 firmware.

Octane is the main factor with map selection. For most pump gas situations map 1 is suggested.

I understand this. Now I am using map 2 with ca tless DP. But due to the smell and sound I am thinking to change it to sportcat. So I wonder if it will be OK to continue running on map 2 with sportcat or its better to change to map 1 using the same Octane Ron 98?

I have a completely stock 328i F30 with 69000km on the clock.
I want to tune it a bit. First I found Racechip Ultimate which seemed good. But someone recommended the JB4 as it is much more complete and reliable, better for the engine and everything.
So I found one for a good price. But I want to know more about it. Will it be easy for BMW to detect even after it is removed, because it is tapped into the OBD plug?

Another thing, is it possible to tap into the wires behind the OBD connection, without using the OBD-plug you can buy. I want it to be stealthy. Which cables should I tap on the OBD connector?

How reliable is it? Can I count on it, I don't want my expensive car failing because the turbo is blown or other damages due to high psi!?

How much more hp and Nm will I gain over the 245hp stock?

Why would tapping wires be more stealthy than using a PNP connector you can fully and completely remove in under a minute?

Because the one I want to purchase is used and does not have the connection. And also I'm thinking of cutting the OBD-wires and put a connector in the engine compartment, that way I can easily remove the whole box when it is at the dealer. A little cable is easy to hide.

From what I understand you cannot use ENET connected to the OBD when the JB4 is connected.
Is it enough to disable it with the steering wheel, and then connect the ENET?
Or do I have to unplug the two cables to the OBD?

There is no connector taking up space and so on. And also I just purchased a used JB4 which hasn't got this connector.
Is it ok to extend the OBD-wires to reach the connector, what gauge of wire is used?

And another thing, I want to connect this to the OBD as I previously said, and update the firmware to support this. Can I update the firmware from my computer before I connect everything to the car?
I don't want to connect it before it supports the OBD features if something is damaged.
Or should I just connect a few cables to be able to update it?

Thank you in advance!

EDIT: Are these the correct wires to tap on the OBD connector?

To confirm, the blue and light grey. This is from the N54-thread, is it the same thing on the N20?

Wires are the same. The JB4 must be installed to load firmware.

Great!
I understand that I must install it before updating, but the JB4 I bought is used and has the old firmware (where you tap the OBD in the engine compartment). And I'm going to tap it directly behind the OBD. Is it dangerous to tap behind the OBD and start it up before updating. Or is it the same connectors that are in the engine compartment?

Would love to have a clear instruction on this to not damage anything.

EDIT:
Just searched about the firmware update for OBD, but from what I understand it is only for EWG? I have a PWG on my N20 328i.
Will there be a firmware for OBD? I want to be able to use the steering wheel functions.

We actually have OBDII PWG firmware under testing. I'll add it to the first post.

Just don't connect the CANbus wires until after you update. Not that it will hurt anything, either way.

Wow great!
Will update before i connect it.
As i have bought a used jb4 will it keep the other users setting even after a firmware update? Could you post a picture of the default settings in the jb4 windows application for a jb4 n20 328i with PWG?

**Cross posted in support after seeing Terry's note on the previous page**

Need some help!!! Just installed a JB4 on my '13 328i (EWG), did the board upgrade and OBDII cable, using the BT kit and app, only using stage 1 right now, and I'm getting a code "CDA904 FA-CAN, message (Status trailer, 0x2E4):Missing".

A) What does this code mean? I had no luck googling.

B) What is the black wire/2 molex connector part of the harness (not the ground)? update: looks like manual MAF based on BMS' youtube videos

C) Do I need to remove the ground and power wires? The instructions weren't very clear. They're currently hooked up.

D) The car isn't registering my mpg or avg speed, and the small display on the gauge pod isn't reading miles remaining in tank (top right of the 6 values displayed).

E) Looking at the gauges on the JB4 Mobile app, I noticed a few times when I let off the throttle, AFR would read 3.8 and stay there for a little bit despite blipping the throttle.

I have no other mods on the car, everything worked fine before.

I just realised I haven't checked if I really have PWG or EWG, but according to the JB4 installation instructions the EWG was available only after 2014?
Tried taking a picture where it is supposed to be, but can't really see it?
Big picture, linked: http://i.imgur.com/Ryut5bT.jpg

Does this mean I have the EWG? I just purchased a used JB4 with PWG, because according to the instruction EWG is only for 2014+??
Can I add the EWG cable to my JB4 easily?

Third edit:
Read almost the whole thread now. From what I understand I can add the EWG harness to a JB4 that has the PWG harness. But what are the real benefit of doing this, as the installation guide states that you can tuck the PWG harness away if you have EWG. Will Map 1 run better with EWG harness or is there no difference at all?
I have a completely stock 328i with EWG (i think, please check the picture).
Will the EWG harness give me more boost on Map 1 and deliver it more smothly?
Can I run map 2 without having DP?
Only run 98 Octane in Europe, don't know if you have the same scale?
