Stinger 3.3L EWG Connectors
 
2 Attachment(s)
Starting a thread for those who are helping test out the new JB4 Stinger EWG connectors.
What are the EWG connectors?

They are optional connections that attach the JB4 to the wastegate actuators on each turbo. By attaching directly in this way the JB4 is able to increase or decrease WGDC in a dynamic way to improve boost targeting. The benefits are increased turbocharge response, ability to correct for under-boost or over-boost conditions, and more top end power as the JB4 is no longer capped by the ECU tuning WGDC limits. The technology is similar to the EWG control for BMW models the JB4 has been using running for many years and includes a PID control loop for smart targeting.

Order connectors here: https://www.burgertuning.com/product...d-infiniti-q50

Availability: We're working on ramping up production but it's going to be a slow process as the connectors used for these are hard to source. For now we'll add them to our site as we have them. At some point when we have a firm date on a large bulk we'll just order up pre-ordering. Rest assured we'll be using this time to further develop and refine the EWG firmware and tuning. :)

How do I install them?

First they must be attached to the JB4 harness by attaching the wires in to the JB4 connector. Be careful to note the connection points/numbers carefully as mistakes here will lead to fault codes and since the pin require a DSUB removal tool can be tricky to fix. IF you do make a mistake you're better off cutting/splicing the JB4 wires to correct it if you do not have access to or have never used a DSUB removal tool before.

EWG Connector 1:
Blue wire: Pin 19
Purple Wire: Pin 9

EWG Connector 2:
Blue wire: Pin 14
Purple wire: Pin 8

NOTE: Some JB4 harnesses have a green wire routed to spot #9 which is not used for anything but blocks installing the EWG purple wire. If you happen to have a wire running there you can remove it with a DSUB removal tool or easier yet just cut it leaving enough length to splice in the EWG purple wire using a wire nut, butt connector, or any other method. The green wire running back to the JB4 harness doesn't need to be attached to anything and can be left sitting there unused.

Plugging them in to the wastegates:

Stinger Driver side connection:
Connectors are interchangeable and either connector can attach to the driver side. The connection is down by the turbo. You can reach it without removing anything on a cold engine. You may need to use a screwdriver to push the connector down while holding the clip in with your finger.

Stinger Passenger side connection:
Either connector can attach to the passenger side. You'll need to remove the airbox bottom to access the connector which will then be easy to see/reach.

JB4 Settings:

Requires v14+ JB4 firmware

User Adjustment Page:
1) 50 across the board under duty bias. This represents a "neutral" base EWG mapping meaning no WGDC is added or subtracted. The base mapping is shown under the FF curve in logs. Cars that tend to over boost will need lower values (e.g. 40 or 45 across the board), and other vehicles that are under boosting will need higher values. The profile can be set by RPM to reduce top end boost taper for example.
2) FF set to 50, this factor is multiplied by duty bias to globally scale up or down the FF mapping.
3) PID gain set to 20, this determines the dynamic WGDC range, how far above or below FF WGDC can go based on boost over/under targeting.
4) Auto Shift Reduction set to 60, this determines how much WGDC is cut during shifts to tune turbine speed change related boost spiking.
5) Stingers models that are flashed should set options bit6 on which will increase DMEBT modeling for more accurate EWG PID control for flashed vehicles.

You shouldn't run into any overboost issues with this setup. :)

Terry @ BMS 01-29-2020 09:24 PM

First order of business is those cars with modified exhaust that over boost, and of course large turbo cars who need more WGDC.

KLR STINGER 01-30-2020 01:51 PM

Just emailed you terry. Seeing as I was the first ******* JB4 user, I need these asap!

asdap2 01-31-2020 06:00 AM

Car model: Stinger GT
I have installed and using the parts below:
JB4 WMI, HKS M45IL spark plug, Agency power intake, Tiar flange BOV, BMS OCC, customized muffler.
I am having over boosting trouble so I would really like to participate on the EWG connector tester.
Please send them with the parts I ordered.
Thanks

*** NOTE FROM BMS *** Some JB4 harnesses have a green wire routed to spot #9 which is not used for anything but blocks installing the EWG purple wire. If you happen to have a wire running there you can remove it with a DSUB removal tool or just cut it and splice in the EWG purple wire using a wire nut, butt connector, or any other method. The green wire running back to the JB4 harness doesn't need to be attached to anything and can be left sitting there unused.

I installed the wires yesterday.

Here is a little walkthrough the install for future reference. What you have to remove and how you access the connectors may differ according to your different mods

The harness can't be plugged in the wrong direction,
but since you won't be able to see what you're doing with your hands, identifying where the little protuberance is located will make it easier.

Here is the "A" side (passenger)
It is located just below the turbo inlet, but because of the coolant hose you can't access it without removing the intake piping. Removing the strut bar will also help. Only one arm goes in so I had to do it one-handed.

https://i.imgur.com/vCRzGjY.jpg

Here is the "B" side (driver)
It is also under the turbo but there is less stuff around so both hands can be used (one each side of the radiator hoses) and in my case I ony had to remove the intake filter. I recommend doing this side first to get more familiar with the connector.

BTW when removing the connector, you need to press the little end that I highlighed by a circle. Pressing any higher won't do anything else than wasting your patience.

Now that you've successfully connected the harness on the actuators. Here is the JB4 side. (nothing new here, just pictures)

PS: If you have WMI installed, getting all wires through the rubber seal will be a little bit challenging but it is doable.

For the routing of the wires here is how I did.
Since both wires are the same length the one connected to the driver side will be too short to route through the rain wipers line like for the fuel wire, so I've chosen to route it along other hoses in front of the engine. (I added tubing to protect the wires, it is not necessary)

Now that the H/W is in place, time to do some testing. :burnrubber:

Hoping this helps.

Is there a simple way to make these pics smaller?...

Beefer 02-02-2020 07:50 AM

Use a computer

Assuming you are using a windows computer, you can scale the picture down in Paint. Just use the scale tool in the options, scale it down to like 40% and use Save As, and select jpg as file type. Easy peasy :)

atr1 02-02-2020 08:44 AM

I was asking for a simple way not involving reuploading and replacing the link of each picture.
Some forums auto resize pictures (at least the displayed size) to fit the screen or have a feature to display only a thumbnail.
I know how to resize pictures on a computer..

Got a couple logs with the EWG wires hooked up. One at 50 bias and one at 60 bias Wasn't sure if you wanted logs on this thread or the original JB4

KLR STINGER 02-04-2020 07:26 AM

Were you having throttle cut or overboost spikes before this? logs look pretty solid with no hint of boost spikes.

Soccerstyle 02-04-2020 07:54 AM

No, not that I have noticed. I think he wanted me in test group cause I have WMI among other mods. Wanted to see what it could do I guess.

DaBears4Lyfe 02-04-2020 10:35 AM

wow this is awesome. Let me know if there is anything I can do to help? Sent you some logs Terry. I was actually getting ready to throw cats on this week as still getting some overboosting at times.

DaBears4Lyfe 02-04-2020 10:38 AM

emailed you some logs terry

Here is a log at 70.

KLR STINGER 02-05-2020 06:44 AM

Terry, with EWG control now, could you now move from additive boost to absolute boost targets? Ie, set peak absolute boost values per RPM?

We still need to find a way to datalog the flash boost target to do absolute maps.

DaBears4Lyfe 02-10-2020 09:41 AM

Nice work on the install guide!

Terry @ BMS 02-10-2020 04:35 PM

Starting to work on a PID control system for the EWG control. Those running them can drop me an email if they have time to log the latest firmware. :)

atr1 02-11-2020 11:30 AM

For those who wonder, my car was always overboosting and now with the latest firmware and settings it is very hard to make it happen. There are still some more tests to do but Terry has made really good progress so far.

I'm really happy with the EWG progress so far, but wish we had a method to add true "DME BT" to the logging channels as that would finally allow absolute boost targets like we offer on BMW models. We'll get there. :burnrubber:

Does the PID control setup remove the ability to manually adjust DC at RPM intervals? like is it adjusting DC based on PID feeback from map sensor?
