Winkfp setup software#

If you are programming back to original (keeping the same software version) this will help you so you don't run out of slots.

If you have an ECU which has filled 15 UIF slots, untick those boxes and it won't add any new ones and run out of space. Some ECUs only have limited space for these, each programming adds a new UIF. The UIF is User Info Field, where the VIN, part numbers, programming date etc is written. If you switch off the UIF write boxes, the ECU will update, but it will not show the new software or part numbers. I also have UIF write in expert mode (you would very rarely need the expert mode) This usually takes longer, so you would only need this if you have an ecu with a damaged file, repaired it with the wrong file type to get it to communicate, and then use WinKFP to do everything from start to finish. If you tick the box, it will re-program the program area and data area together.

WinKFP would check the data flash, assume it has the correct program flash, and only re-write the data area. If you put the wrong data flash onto an ECU, this is where you will need the 'force program area' tickbox. Usually data flash areas can be exchanged with other data flashes for the same program flash. On just one of them, the 330d for example, you might see that they all share the same program flash, but different data flash for auto or manual, different emissions specs etc. You might see this as a 325d and a 330d have different program flashes on the same ECU. I have fast baudrate off, 'force program programming.' only on in special cases, for example if you suspect a problem in the original program flash, or you know the data flash and program flash are not compatible.ДЇor example, an Engine ECU will have a program flash which is shared by a few versions, and a data flash which is specific to differences.
