BMW E90 WITH EDC17CP02 ECU ~15 MINUTES TO READ EEPROM

[Panathaole]

Hi

today i encountered something that had never happened to me before, i read with ktag an ecu from bmw edc17cp02, with 95640 eeprom, I read the flash, a little slow but okay, when ktag started reading eeprom (95640) it took almost 15 minutes to finish , has this happened to anyone else?
(Car start fine after programming)

This ecu have 2 eep data.
1. tricore eep (isn,vin)
2.smd eep (in here no vin,no isn.probably only same adaptatin data )
And with clon k-tag ...99,9% after programming tricore eep corrupted and car no start anymore.

You lucky if after programming you car start and work,probably your's k-tag is original.

Thanks brend for your answer....

My ktag is clone reworked, it read the 1766 with 1536 kb but no eeprom in mcu, only 95640....

So it maybe reads only maps, like i read it in obd....
In ecu is a sticker of last programming 2014.....

cp02 and or c06 tc flash and 95640...

but 15 min it never took, in my cases for 95640...

try to read second time and compare...

so no internal eeprom in this tc mcu.... and yes, it takes much more time to read eeprom than the flash......... very weird

i don't have the ecu to test... i put it back in to the car after remove the DPF, (i read tree times the flash and is identical...) car works fine.....

here is eeprom if someone can take a look....

Where did you bought your ktag reworked?
