hello i dont know why optican reads it !!!

i had this problem by myselfe with this base copy shit !!


looks like MTM or ABT

i had this on audi s3 8l year 2000

to read the software is possible but write is impossible !!

what did you do now

did you desolder the chip from the base copy

you can solder this chip on the ori base !! desolder the complete shit of base copy !!

it works !! i have done many of this ecu

hi

if you dont want to desolder you cant read/write the ecu !!

i think there is no optican clone !!


i have a genuine optican dual master system !! this tool is expensive !! 4500 for the master version !! but i think its a very good tool !!!

did you try it with a MPPS ?? maybe this tool will do it !!

you can send this ecu to me and i can read it for you if you want !!


king regards

Well this is what it says when I try to read it on the bench:

ECU reports programming session preconditions have been met.
Negotiating communication timings.
Successfully changed to new communication timings.
Requesting security access.
ECU reports that security access request was rejected.
Starting diagnostic session.
Disconnecting because no response was received for the Tester Present message.
Disconnected
100% complete.
Validating memory layout failed.
Restoring Windows sleep mode.

This is what it says in the car:

Requesting security access.
Security access granted.
Validating flash memory starts at 0x00800000 and ends at 0x00900000.
Memory layout is valid.
Starting to read data block.
Calculating flash checksum to determine if reading is necessary for range: 0x00800000 to 0x00810000
Flash checksum does not match, reading flash data is necessary.
Requesting upload from ECU for address range 0x00800000 to 0x0080FFFF.
Request upload from ECU succeeded.
Starting data transfer.
1% complete.
2% complete.
3% complete.
4% complete.
5% complete.
6% complete.
Data transfer failed.
100% complete.
Reading ECU flash memory failed.

I'm assuming that nefmoto can not read this, but I switched over to my stock ECU, and couldnt read that in the car either? What the heck am I doing wrong? It validates memory layout, but only gets to about 6% done and then fails on both chipped and stock ECU's. I'm at a loss, but after all attempts I'm still able to start the car with both ECU's.

Ok so now I've got a galletto cable. The software says boot mode for 29f800BB, but as you can see in the previous pictures (if you looked!) that the chip inside my ecu is a 29f800BT. Will this cause a problem? Does that have a different memory layout? Thanks for everybody's help, I'm pretty close to either a total failure, or total success. Either way it's been a real learning experience. Thanks to everybody for their help. Lots of people have pm'ed me and what not pointing me in the right direction. Great site, good people...

So I did search...duh!! Thank you for the suggestion. This is what I found posted by Tony:


So I'm going to assume that to read I could just use the 29f800bb to read!! Will try Tuesday or Wednesday when I have some more time. Thanks!

Well, I planned to do this to get into boot:

As soon as I find time! Hopefully later today, but with it being a BT and not BB I think the above thread should work for me? Wish me luck

No sir, I was going to go for pin 27 on ram like in the picture at the top of that thread...
