NPOW is the power kit and the little - means you don't have it. If you seek out UN73;2TC&NPOW;1003500-1203502, the latest ZB number is 8684952.

I have been struggling to figure out which ZB number to use but I followed your process here and it worked like a charm.
For those confused about finding the ZB number as I was, just follow RocketSurgeon's suggestion. Find your current ZB number using INPA (mine was 8684988), then look in the e89 DATEN file and find the kmm_ATSH.txt file. search for the ZB number you have in there. When you find it, the header above it will list which cars it applies to. in my case, I have an E90 335i US spec so rather than UN73, my product type is PM53 and the header in the kmm_ATSH file was
PM53 | PM57: -NPOW....
I searched for the PM53 | PM57: NPOW header and it then lists all the codes, the last one is the most up to date. in my case, the latest code with the PPK is 8685036.
Once I updated the ECU in WinKFP, I skipped step 7 which was writing blank FSW_PSW.MAN from NCS Expert. Supposedly you need to do this to remove an error that triggers an check engine light, but I test drove the car without performing this step and dont have any CEL.
