210 ESL MCU1 identification

[clauberty]

Hello

my ak400 head a problem and now i need to generate key for an 211. Key data get corrupted ak400 read just 75% from the key, other key will read 100%

problem was that when come to read ESL it wold read just 1 MCU when i switch to second position read data error

So i check wire and guess what instead to switch K line between pin 3 and 4 was soldered to switch between 3 and GND

Noe the problem is how do i know witch one is MCU1 and MCU2

if somebody can give me the right schematic it wold be very nice

In attachment is what i read

Thank you

NO problem if you dont know Mcu1 or 2
just write this files to your mcu1 and 2

goodluck

Thank you so much for your fast answer

now how do i generate the key if i do not know the cpu nr

The guide say that have to load CPU 1 EZS + CPU 1 ESL CPU 2 EZS + CPU 2 ESL

It is not necessary to load ESL ?

Thank you

send me ezs mcu bin

[clauberty]

send me ezs mcu bin

Start to unsolder and read

[vanos batam]

Start to unsolder and read

only mcu 1

[clauberty]

only mcu 1

Ok when i read cpu already unsolder


What do i need to do

write key bin to NEC
write MCU1 eep
put ESL bin that you uploaded in both mcu same file ?
and ... start the car ? car is 1.5Km from my location

Can i test on the bench it will unlock the ESL ?

Thank you
