remap/write ecu Audi A3 1600 cc, 90 hp TDI year 2012

[maurof650]

As the title suggests I would like to remap the ecu of my Audi A3 1600 cc, 90 hp TDI year 2012.
That's me back is the where to dismount, send the ecu and not being able to use a car during the time necessary for the job.
Since dipongo of the galletto V2 version 48 and a MPPS12, disposing of the map I can also do by only via serial? Or are there any particular problems?

do it with the gallo , is mounted on a siemens pcr 2.1

I checked .....my car has a control unit Continental.

I checked .....my car has a control unit Continental.

then your machine is equipped with a control unit continental simos pcr2.1 and I'll explain from 0 what you need to do if you want to remap your car and you must do exactly as I tell you and not adding removing something to your liking:

-disassemble the unit
-open it and do the release with resistors etc (as shown in the diagram that you should have based on the programmaotre use)
-close the unit and re-mounting
-read from obd
-modify the file
-write the file

finished good job.

But if you were to read an ecu with antituning without unlock it , you get error? Crashes? Or the law equally with maybe wrong data? (Using the rooster)

In the meantime, I am reading in serial to make a copy of the original map? What measures should I take? As we read?

steps are written in the manual of the FG, Siemens PCR2.1 (1.6 tdi VAG)

This ECU need first to unlock and then can be read / written on the plug OBD

[the shiston]

but you must open to unlock it, or is always with the cock^??

Do not do it with none of your gear.
