I keep seeing these threads about throttle issues and those who know me know i've been down this road before with the jerky/jumpy throttle issue in the first to second etc shift/low pedal openings. Anyway im going to show you guys how to use WINKFPT to flash your DME with euro software that will correct the issue. Using euro sw is also a fix for SAI issues as euro m5's dont have SAI, you can also some euro sw versions turn off the rear 02's, another popular request. So short disclaimer, Do this at your own risk, if you don't follow directions and brick your DME, don't blame me. im not going to provide links to the sw, dont ask. google is your friend.
things you will need,
1 laptop with a serial or usb port capable of running the flashing software.
2 WINKFPT and inpa or dis.
3 a K/L line interface cable
4 a power supply capable of keeping the voltage at or above 12.5v during the flashing process.
5 a Progman disc to extract the programming data from to install in the WINKFPT folders
i'll attach a .pdf of how to update WINKFPT after you have it installed.
Once its all setup the flashing process is very quick and painless. takes about about 2min if that to do a data flash, which is what the majority of people will be doing.
ok so first you want to see what the current sw is thats loaded on the DME. You can use INPA, DIS, to read the program #'s and iirc you can also use WINKFPT to read the UIF(user info field) which will show the history of how many times the DME has been flashed and with what program/data numbers. The majority of the m5's running around in the usa, especially because of 12-06-06 recall will have 7837965 as the base/program number. So i would say 90% of the m5's on the road in the usa are running this sw set base # 7837965, program # 7837951. which makes this easy as we only need to do a quick update to program set to update it to euro sw.
so here we go, what we want to do is open WINKFPT and click "COMFORT MODE", then "Choose ZUSB", the box will pop up, scroll down and choose 7837963, the screen at the top should show the two program #'s. Now go down to the bottom and click the box "Done", after you do that a box will pop up asking you to enter the vin. Enter the complete vin and make sure it is correct. Once the vin is entered the two programming files that are used will be added to the middle of the screen. Also at some point click the "configuration" box on the top of the screen and make sure it looks like the pic below. Ok now you're ready to do some flashing. If you have everything set up right, cable is connected to vehicle/laptop, steady power supply is on, shut off all unnecessary consumers inside the car, radio, nav screen, lights etc, now on the bottom of the screen hit the "Program" box. It should say something like "Ecu can be programmed 12 more times, program ecu" click yes/ok and programming will start. The bar at the bottom of the screen will progress left to right and count up t0 100%. after successful programming it iirc will say programming ok. Now shut of the ignition for a minute, turn it back on, wait 15sec, start the car. If you did everything right now you'll have silky smooth throttle and now secondary air pump screaming at you in the morning.
One nice thing about WINKFPT is that it pretty much won't let you screw up. If you dont have it setup right it wont ever get to the point where you can do any flashing. There is a real good how to/pdf floating around im going to try to find and attach to the thread. Also in the PDF's the E70 is just an example, what you want to do is from the cip installer dir you want to grab the "SP DATEN E39" folder.
