how-to: ECU-based direct boost control

Man, there really is bugger all all that's been done for 90550701 ...
I've never been able to datalog WGDCC, it just sits at 63.5
Just like this guys: https://www.evolutionm.net/forums/ec...-wgdccorr.html
I'm guessing it' got something to do with that 8A and 8B thing.., but I'm not confident with changing MUT table values based on guides for other ROMs, has anyone ever done this for 90550701 before?..
Attached is my Evoscan formula for WGDCC & What I get whilst logging.
-Yes, I know i should just run an VIII USDM ROM, but I like the ALS Capability of the JDM VII ROM

If so, we would need to see a data sheet for the sensor to even know if it's possible. The voltage operating range would have to match the OEM sensor and you would need to know the scaling.
If that's not what you are asking, could you please clarify / elaborate the question?

Are you asking if you can use the map sensor the AVC-R came with*, wired into the ECU instead of the JDM map sensor / omni (etc)?

Ok let me clarify.
Yes I currently have the AVCR with the avcr map sensor wired into the ECU with a 3 port BCS to control boost via the controller and log boost on EvoScan. (As the JDM 8 never came with a MAP sensor from factory)
My question is if it's possible to use the MAP sensor off the AVCR that is already connected to my ECU (logging boost) to control boost (ECU based boost) instead of the ACVR controller?

If you are able to log boost through MUT via evoscan, then yes you could use that signal for ecu boost control.
TBH that seems overly complicated and more likely to be problematic considering the alternatives.
