Hello all,
Looking for some insight as I think I may have messed something up. Back in January I attempted to update my DME using winKFP. I have a 2000 BMW 540i, last 7 of the vin are GM67740. I used I used daten 50.2 files to update the DME.
I don't recall much of when I updated, but I'm pretty sure WinKFP selected the ECU family and all that automatically.
Here is a photo of the software/hardware info from Inpa:

The car seems to run fine, but it appears I am getting lower gas mileage, and when I am driving at a constant speed the throttle blips every few seconds.
If anyone can help me flash the most recent, correct software that would be greatly appreciated.
I am looking for info as to what ECU family to use and the ZB-Number to use.
You have the correct / latest version-

That one is the latest update for vehicles with option S204A which is showing on your car.

You have the latest correct update to your DME, 7539304, for S204 Shorter final drive ratio option your car came with.
I would look for other causes of you fuel mileage loss, such as oxygen sensors, vacuum leaks, and the like.

Okay, any reason why I would get a throttle blip at constant speeds? For example if I am going 45 and the throttle is steady at a certain RPM it will blip then go back down.
Could it be because the transmission software hasn't been updated at all? I reset engine adaptations after the update, do I need to reset throttle adaptations separately?
