Thanks for the tip! I will be using a ReFlex for port injection, will look at using it to provide the PWM signal.

To be honest, I think the best route for you here would be to pick up an S55 DME out of a wrecked one (MEVD 17.2.G) and have someone like Levan @ BimECU clone your vehicle's ISN to it.
ReFlex can provide a PWM signal indeed, but it will not be able to provide one to match the boost curve that the DME is commanding / controlling for the other bank.
Additionally, you will have a big fueling issue, as the closed loop lambda feedback will only be from 3 cyl. Even if you merge both downpipes in as short of a distance as possible, it will still be a bit far for accurate control.
I would get the S55 DME, clone your ISN, and then have your tuner code out / disable the S55 related things you aren't using (2nd hpfp, w2a items, etc)
I just spoke with Levan, he replied no to your email because you were requiring too much on his end. I had said they would clone the ISN from your DME to the S55 DME. That is all BimECU will handle.Soooo, @Bimecu said he/they cannot help , any other suggestions?
If the ReFlex is mirroring exactly what the DME is doing why wouldn't it be able to match the boost curve? can you explainReflex can provide a PWM signal indeed, but it will not be able to provide one to match the boost curve that the DME is commanding / controlling for the other bank.
I already considered this; I may have to switch tuning platforms (SORRY!) as you guys don't allow for additional inputs to the DME yet.Additionally, you will have a big fueling issue, as the closed loop lambda feedback will only be from 3 cyl.

ReFlex: mirroring will likely not work (even though ReFlex receives final WGDC over CAN from the DME, and then can output it on Aux1 as square wave PWM).... because.... that WGDC is derived from the DME internal electronic waste gate control model, through many tables. There is absolutely no way that will match what the DCCDPro controller is doing for converting PWM Duty Cycle to Electronic gate control.If the ReFlex is mirroring exactly what the DME is doing why wouldn't it be able to match the boost curve? can you explain

Thank you for sharing!ReFlex: mirroring will likely not work (even though ReFlex receives final WGDC over CAN from the DME, and then can output it on Aux1 as square wave PWM).... because.... that WGDC is derived from the DME internal electronic waste gate control model, through many tables.

For example, its usage range is 5-95% PWM DC input. The DME (calculating things the other way....wgdc -> gate position control) uses 0 to 100%
None taken by me, and yes, I am no way in "my depth" when it comes to knowing the possibilities with these cars and knowing what may or may not be possible with coding. I did take your advice; this is why I can report that the person you recommended declined to help.No offense, but you are clearly out of your depth here on getting this project to actually work. I've told you what I would do to guarantee it work. You can take my advice or not, up to you
Like I said earlier, he declined because you asked him to also perform all the duties that your tuner would need to do. BimECU would clone ISN only.Thank you for sharing!
