Read and write Bosch ME 7.9.52

[flamingsn3Ak3r]

Hi guys,

I just took possession of a Toyota Yaris 1.0 (Engine is 1kr-FE),
this machine is equipped with a Bosch ME 7.9.52, however, before starting a
in the processing I need some advice.
Therefore, I will use the Ktag Clone the most recent version.
On the guide to be able to read this ECU says to do 2 welds with wire,
1 to the PIN of the Boot and 1 for the PIN CFN1 and only with this it is possible to read and write
the ECU.
However, since I'm not sure I've tried the other; on other sites they say to put 2 resistors of 1Kohm each
others, however, put the other wiring in the ecu as in the picture:



Can someone help me?

Thanks to all of you!

I would add that in the guide I recommend to unsolder the 2 wires,
I believe in order to not create of the masses or contacts that would jump the ECU;
however, I wonder if they isolassi in the event of a new change, not to stay
to resolder again?

Greetings

Hello, please follow the guidance of the ktag go quiet...

No need to unsolder the end of the procedure anyway... Except if you don't want to solder get two tips to spring... However if balances when you finish remove put black mastic around the edges in close

UPDATE:

I opened the ECU and I made the connections in direct mode (Welding + link to PIN)
when I went to do the backup with the Ktag does not recognize me the device and asked me
select the pugin suitable, in this case I have selected "Bosch ME 7.9.51 (Toyota P54)"
has effettuto the total read and has saved me 3 Files:

- 1 file with the extension .MPC (I think the one with the maps)
- 1 file with the extension .EPR (I Think E2prom)
- 1 file that I gave the extension and name (I think that is the union of the 2 previous files, and I have given the extension .ori)

I tried to open the file with Titanium, and if I put the 3 files with anyone located the drivers for this ECU
and the only files where I can "see" some maps are files with the extension .ori and .MPC.

If instead I put the files in WinOLS (.ori and .MPC), I is the ID of the ECU (HW and SW), and recognize me maps of the potential (26 maps)

Now I wanted to know if reinserissi the mapping changed even if I do not recognized the ECU might go into the block?

Wait you got the file that you read, and you've changed right ?

Still get the mpc file modify it and then re-enter on mpc stop nn run any risk

Before writing tells you.the cas sw and hw if they are the same, proceed with the.write and the game is done but.you have to write.the file only.maps that you have edited ... ok ?

[flamingsn3Ak3r]

Hello excuse my inaccuracy,
still, I have not changed anything I wanted to be sure before
put me to work.
However, as I said before, during the procedure the ecu has not been identified,
but the reading was checked in the box for backup) has gone to a good end.
If I wanted to do only the reading of E2prom or the area where there are maps
she did not recognize the same and made me to redo the full backup.
However, at this point I think it's the usual thing, you just have to have all the files separate.

the writing test I have not done yet

[carfree]

Then do the backup you have done well ok we can save it's always that ... now the only thing.that is left for you is to take the map file you edit rewrite sigolarmente.only that and.it should start
