NefMoto

Hi..!

I read 1Mb file with MPPS via OBD of an Audi TT 1.8t 180cv (2000) with eeprom 29f400bb, that is 512Kb large.. (I didn't do the BooT mode...)

But, there is a problem.. Because the file reading is 1 Mb large and the eeprom is 512Kb   ..

I have this questions:

1) Which file shell I rewrite in ECU via OBD with MPPS ? (the file 1Mb or 512 Kb large..)?
2) Why is used the Boot Mode ? And why is it more safety than normal reading via OBD ?

Write it back as 512kb. You can use nefmoto if you like. Bootmode is safer as it doesn't use the OBD protocol, thus the eeprom contents are not altered. No possibility of being stuck in programming mode, or disrupting adaptations.

I never try nefmoto.. Is Nefmoto safer than MPPS..?

I don't understand this... If, I read and write in Boot Mode via OBD (with MPPS or Galletto), which is the protocol used in Boot ?


Thk YOU!
 

Do you know where can I find information about Boot mode for ME7.5 ..?


I have this questions :

1) What is the procedure of the boot mode ?
2) Are there two options to do the boot mode..? (with ECU connected from the car via OBD,  and with ECU disconnected  from the car ...?)
3) Can I do the procedure of the boot mode to read and to write the file of the ECU, or only to read ?
4) The file read with boot mode is the same of file obtained via OBD..? Or boot mode gives a bigger file..?

With MPPS and ME7.5 works for me great :

Ground pin 24 from AM29FB400/800 with a 1K resistor, i solder a switch between pin 24 and ground.

* Start MPPS
* Put the switch on ( Ground pin 24 )
* Powered the ecu
* After 5 sec put the ground switch off
* For checking, press : ECU ID

When you see the ecu information, press read..

When he say, put ignition off, then on, do that with the right cable ( Bench flashing ), click oke and he read the flash..

Ok, Thk you for the Guide..

I'll try it the next week..!

Had an issue the other day trying to read a car using mpps. Never found ecu even with dash fuses pulled. It will work on a bench though.

Aftermarket Audio/Radio could be a problem.

Vcds could see it though.

But, why do we remove the dash fuse..? (I read the Ecu with out remove the dash fuse..)

If, we remove dash fuse, we can read with more seafty..?

last time i tried to read/write to me7 ecu with mpps i couldnt get bootmode. pulled the dash fuse and then i couldnt see the ecu either

On mpps screen it says pull dash fuse if there are errors.
