Corsa 1.7 cfti

[maurineu]

Hi anybody may can extract the pin of this one?
Also, i got a 898000 8206 ecu with chip 93a86, i only found a 898000 8207 , it will be compatible or will need programming?
I did take the chip from the fried ecu as was completely burnt, can i just swap chips?

eeprom not read correctly

[maurineu]

Might be the wrong one? I have read and verified twice and it checked ok. Its the 502 in that ecu

eeprom not read correctly
Might be the wrong one? I have read it with xprog /microchip 93xx86a 16bit i believe. There is three of the same this is the 502
Im at work.now but still soldered in the rig , i wanted to be sure i have the right reading before moving it, i will try again in the morning, if i have to read in other configuration please point it to me, im a bit newbie on all this game, but trying to learn as good as my old brain lets me.

read as 8 bit

[maurineu]

I will, back tomorrow, thanks

There we go, read 8 bit

I don't know what you are doing wrong but the reading is wrong

[maurineu]

I don't know what you are doing wrong but the reading is wrong

Might be the wrong eeprom? There is 3 in a row of the same there, its not much information about on internet, i believe i found only one post with this type of ecu
Tried reading as ST M93C86 8 bit , however i believe. I have seen somewhere this is a 16 bit or 32

Hi, thats the one im reading, but for some reason the readings are wrong, its an S93A86 ADAVG5 so in xprog i found 93xx86A to read it but may be wrong, not much more options in xprog

[miroopel]

Read as 93c86

Xprog , by the moment the one i have, maybe something wrong with the soldering? Not very tidy mine, but checked with a magnifying glass and the unions looks ok

[maurineu]

Thank you very much, now the next question.
Will be enough to swap that eeprom or will need to extract the pin of the working one?
Remember its 1 digit difference in the numbers of the ecu, so may be hw or sw as i cant find any description of what means what in all that numbers
