I can show you my programming and coding results few day before for my 545 e60 2005..with K DCAN usb…
Requirements for installation of ISTA P : min 200 gb free hdd,min 3-4gb RAM,and min 2ghz cpu speed,i hope you know…
I don’t know for sure do you need to keep ISTA +,because I have installed Ista + before ISTA P version 3.65.0.500 which I have…
I don’t remember thru that installation of ISTA P that I was needed some kind of activation key, only reg fix or something …but anyway, now I have a new version of ISTA P3.65.0.500 so you can go thru installation of 3.65.0.500 version [85 gb]…[there is ISTA P loader folder with activation key ]
About my experience, I must tell you that with K DCAN usb cable everything was fine but slow…
For my CCC Application programming time was about 8 hours!!!
Everything else was much faster, think I have 38 ecu programmed and coded thru ISTA P….
I have done full car programming in about 12 hours!!!
Yes I know it is crazy, but when it started, I must to finish everything…
BMW ICOM is much better[and faster] solution!
But for my car it was a problem for old ZSUB numbers which I did not managed to program
all ecu-s thru WinKFP ,one by one..only few of them.
Everything about ecu-s in my bmw was from 2005 [integration level plant E060-04-09-550]
Anyway I think there is no problem for programming 1 ecu with K DCAN usb, but keep in mind that voltage of the battery must be backup all the time and key must be on ignition position …
And one more thing, for me WinKFP is also good solution for programming, because when you have new ZSUB numbers {ecu numbers} ,you just need to find that number in AIF thru INPA, and after that you just in WInKFP comfort mode [F1] ,put that number [F1],enter VIN [F4],than DONE[F8] and than [F3] again and everything is done!
Or just update ecu with [F3],than select ecu family,enter VIN [F4],than [F8] and again [F3]…
I hope you don’t mind for this long thread, and also sorry for my English writing ,because I don’t know better…
PS:ISTA P is only for programming and coding ,not for diagnostic….so keep your ISTA +
