    2000 540i DME Software?

    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 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?
