How do you log boost on EvoScan
Yes it is an update, the stock map sensor can only read up to 1 bar of boost so you have to make the adjustments for it to be able to read 3 bars now.
I just ordered mine from a groupbuy here so I should be receiving it very soon...will keep you posted on how the setup goes.

The issue of the EGR is that you cannot measure directly the quantity that you are feeding into the intake manifold.
In order to estimate that you need the quantity of fresh air (via MAF) and the pressure inside the manifold (via MAP).
With a relative pressure balance, you can estimate the quantity of EGR.
This is important because you don't want too much EGR (efficiency loss) and not too less (increased NOx emissions).
Usually, the EGR is switched on at low loads, that's why the US cars have just a 1bar MAP.
If the car doesn't have EGR, then the MAP is not mandatory. It's just money that the OEM would put in the car without any necessity

P.S: I'd rather have that. I'm wondering if the 88840017 has the SW routine to use such a sensor. Does anyone know that?

no sensor, no wiring and no provision on the inlet manifold to install a sensor (you 'll need to remove the manifold, drill the hole,....) on our EDM evosso as I have an AVC-R , I've had the same idea as you : tappering the AVC-R sensor , feeding the signal to some unused ADC pin on the ECU and log from the ECU with Evoscan.
USDM ECU ADC pins here : (from JackofTrade post)
-----------------------------------------------
ADC poll subroutine #1
ADC CHAN MUT_REQUEST ECU PIN (USDM Evo IX) r5 RAM ADDR
02 10 (Coolant Temp) 44 FFFF6A46
03 3A (Air Temp) 62 FFFF6A56
0E-1 (*NOT USED*) BD (NOT AVAILABLE) -- FFFF6A58
04 8C (Barometer) 51 FFFF7C24
09-1 13 (O2sensor_front) 71 FFFF6A64
0A 3C (O2sensor_rear) 73 FFFF6A68
07-1 3E FFFF6A66
08-1 3D FFFF6A6A
0B 38 (MAP) 92 FFFF6AEC
0C 39 (Fuel Tank MDP) 93 FFFF6AF0
0E-2 87 (Fuel Temperature) 96 FFFF6AF4
0D 88 FFFF6B02

08-2 (*NOT USED*) 97 (NOT AVAILABLE) -- FFFF6B06
0F (*NOT USED*) 83 (AVAILABLE) 64 (C119) FFFF6B0C 5 volts = 255 . no pull up
ADC poll subroutine #2
ADC CHAN MUT_REQUEST ECU PIN (USDM Evo IX) r5 RAM ADDR
01 14 (BATT_VOLTAGE) 60 (?) FFFF6AC8
05 17 (TPS) 78 FFFF6ACA
09-2 (*NOT USED*) NO_MUT (NOT AVAILABLE)-- FFFF7346
07-3 (*NOT USED*) NO_MUT (NOT AVAILABLE)-- FFFF7348
4D 96 FFFF7676
ADC poll subroutine #3
ADC CHAN MUT_REQUEST ECU PIN (USDM Evo IX) r5 RAM ADDR
06 30 (KNOCK_ADC) 91 FFFF6AEA
----------------------------------------------------------
I've found posts describing how to do it for logging AFR with a WB connected directly to the ECU
here : https://www.evolutionm.net/forums/ec...ial-cable.html
but the mods where for the US xxxx15 ROM and so far I've not found how to adapt it to our 16/17 ROM
Maybe we could try to join our effort and get some help from some ECU disasembling guru's on this forum ?

I'd like to have it, but I think that my map doesn't have the ruotine (and basically the cables) to be able to run a MAP
The alternative is to use a free ADC and apply a patch
As I've understand the EGR "map" sensor, it's basically used by the ecu to determine whether or not the egr is opening at the right time or not. It does this by checking to see if pressure drops when it's commanded open by the ecu. Therefore it's a 1 bar sensor.
With the installation of a GM or Jdm map sensor, What needs to be connected? vacuum line? electrical line? and where to?

Secondary AIR supply is mainly used to get the car to operating temp asap... this is why europeans have it on most of their cars (vw, audi, MB, etc....) Japanese don't need this because they aren't in cold weather most of the times... sorry for the ot session...
