BMW K+DCAN cable vs ICOM A2 (ICOM Next)

Here we discuss the differences of K can vs D can cables vs Icom emulators, ideas of what the hardware&software, protocol, car and function differences.

Speed best speeds should be through an ICOM with the MOST adapter theoretically faster, but in reality, it isn’t actually much better speeds
Stability a lot more stable esp. when it comes to programming less stable less stable
Diagnostic Yes Yes Yes
Programming/Flashing used with diagnosis and also programming not safe to program modules not safe to program modules
Coding Read/Write zero issues R/W with a K&DCAN cable R/W with a K&DCAN cable
Protocol fast protocol, allows to secure flash software and read/write access the entire memory slow serial protocol, flashing would take ages and errors could occur. Also, not possible to access the entire memory slow serial protocol, flashing would take ages and errors could occur. Also, not possible to access the entire memory
Similar to Similar to JTAG programming Similar to RS232 bootloader access Similar to RS232 bootloader access
Tips BMW ICOM can be used with diagnosis and also programming. While DCAN cable can do all of those it is not safe to program modules because there have been a lot of cases where modules were bricked. You can only get your 1B file using FSC generator with ICOM on an E series car but cannot generate 1B file using a DCAN cable since it will give you an error. There is another way though of getting your 1B file without using an ICOM on an E series through the USB port inside your glovebox accessing the hard drive directly. Rather than going through all those stuff, it is more convenient to just buy the lifetime FSC code and be done with it.

 

You program a module if you want to update the software to a newer one or if you a retrofitting a new module and want to flash it. ICOM is a lot more stable than dcan cable when it comes to programming. And you are right there are modules that takes hours to finish and any interruption in the process will surely brick that module. You can get a cheap china clone ICOM but finding a refutable vendor selling a good working ICOM is not easy.
