Lada Niva immo problem

[tarts1999]

Hi
One Lada engine ecu burned out. I have new used ecu, so I need immo off. I try one solution, but no help. Can someone tell me, is my solution good?
Car is Lada Niva 1.7
0 261 201 208
95080

MOTRONIC ME 7.9.7

Thanks!!!

Try resolder eprom from old to new ECU

Try resolder eprom from old to new ECU

I allready try it. Old eeprom 95080 is dead, no communication.

take a picture of label and post here, I have immo off dumps for a few versions...

Thanks, I try it tomorrow!!!

I think you will not make it more difficult to leave your result

Now after the holidays I try badenaleks dump. I can not write it to eprom. Programmer gives error. It seems that this eprom is write protect. I buy another 95080 eprom and write this dump for it. Car still not start. Engine light in dash do no light. Immo is still on. Starter do not rotate. All wires and currents are ok. Maybe this eprom what I
buy is not right. I buy this:

EEPROM SPI 8K, SMD, 95080, SO-8-8 Memory Size:8Kbit Memory Configuration:1K x 8bit Clock Frequency:10MHz Supply Voltage Range:2.5V to 5.5V Memory Case Style:SOIC No. of Pins:8 Interface Type:Serial, SPI Operating Temperature Range:-40?C to +85?C SVHC:No SVHC (18-Jun-2012) Base Number:95080 Device Marking:M95080-WMN6P IC Generic Number:95080 Interface:SPI Logic Function Number:95080 Memory Configuration:1K x 8 Memory Size:8Kbit Memory Type:EEPROM Memory Voltage Vcc:5V Operating Temperature Max:+85?C Operating Temperature Min:-40?C Package / Case:SO Supply Voltage Max:5.5V Supply Voltage Min:2.5V Termination Type:SMD Voltage Vcc:5V
Does anybody any ideas?!

Thanks!!!

Look at chiptuner.ru EEPROM, there is also a program and information on how to disable the immobilizer. And kill IMMO and bridged two pins to work around it. Sait Russian!

Check the weight on the body and engine. Programming this car on the russian programm and adaptor.

weigh carefully runs on the board on both sides rather had a problem with a car and found that there was no connection runs in this section

[tarts1999]

Now I mesured voltage and found, that eeprom 95080 pin 4 and 8 do not have +5V. What chip make +5V?

diagnost81 (http://www.digital-kaos.co.uk/forums/members/352839-diagnost81/), thanks, but that site I allready read.

Does anybody have circuit diagam for that ecu? I have bosch esitronic diagram. Maybe it not correct. Some "+" or "-" are missing?!

It is quite normal for Lada Niva, often have moisture in ECU, if you can fix it you can use the file from this thread: http://www.digital-kaos.co.uk/forums/search.php?searchid=13008603

Thanks for all, who help me. Car now works fine. The problem was that the owner had connected the battery terminals the wrong way and there was a short circuit in engine ecu. I repair ecu, write immo off dump from my first post and voilaa, car started!!!
If someone need immo off dump, then dump from my first post is good, works!
