Need help identifying maps in EDC16 for VW T5

[cocktailyogi]

Hi,

I am actually trying to understand the map-structure of EDC16U1 from VW T5 AXE-Engine.
it is this ECU: 070906016AP

I was able to identify plenty of maps, but I do not understand what the maps on the following locations do:
DDFDE Torque Limiter?
DFF94 is it smoke limiter?

E0350
E5D80
EC740
EC834
EC928
ECA1C
D35CA

Where is SOI Maps?

I qould be really nice, if somebody could point me into the next direction.

File is attached

Greetings,

No Smoke limiter map, you have Lambda Maps instead of Smoke limiter.DFF94,E0172,E0350.
SOI maps,E220B,E23C8,E2588,E2748,E2908,E2AC8,E2C88,E2E 48,E3008,E31C8
DDFDE 23X3 is Torque Limiter/atm pressure

For the record:

E5D80- InjCrv_phiMI1HCDes_MAP- Main SOI during PoI2HC

EC740- PCR_pBDesRgn1a_MAP- Boost Setpoint A during DPF Regeneration
EC834- PCR_pBDesRgn1b_MAP-...
EC928- PCR_pBDesRgn2a_MAP-...
ECA1C- PCR_pBDesRgn2b_MAP-...

D35CA-AirCtl_mDesBase_MAP- EGR base map

Okay, you got me....
I have no idea, what the map "E5D80- InjCrv_phiMI1HCDes_MAP- Main SOI during PoI2HC" is doing.
I can see, it comes after the SOI-Map-Sequence and behind Start-Correction-Maps.

Kind regards,

Reference angle for calculation of Post injection SOI based off Main SOI.
Don't worry about it- it's pretty useless for your needs but you did ask about it...

Okay, thx for your patience.

Now I am interested. Is Post injection only for DPF regen or also during normal operation on a non-DPF-engine?

As far as I'm aware no DPF= no post injection.
