Read and write Bosch ME 7.9.52

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 ?

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

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

The file that you say is the one that has the file extension .MPC?

Pero it seems strange to me nn identifies you.l ecu mancu an id you can do

You should be mpc, put it on the ecm and see if.are open to you.the.maps.and.what

it is precisely for that that are in doubt,
but again, if the file .MPC put it on WinOLS
on the properties of the file to recognize the type of machine
and all the data in the ECU:

ECU: ECu: 0261S06137
SW: 505717

This is what it says WinOLS

Instead, Titanium does not recognize the file does not find compatible drivers
to be able to see well on the map view that I see is the IEEE 16-Bit

And select it you on the ecm put the model and brand you should trovarr

are to pc ... check on something, and I tell you ..

I tried to insert the drivers but I do not think that they go well

I confirm the ecm even if you do not find make on the brand and select the Toyota model Yaris start search and select the right driver ... your drive and open all the maps available selections edit save write on mpc ...

how do you not think that they go well in that sense excuse ..

how do you not think that they go well in that sense excuse ..
and a 1000 68 horses ?

they do not go well because the driver with his address
are not right because if you look at the table, but also in 2d
the curves are not and cannot be those.
However, it is a 69 hp.
from what I can understand you have a version of the titanium cracked
and surely you will give the driver of the 69 obsolete(yellow), however,
I also tried that and the curves are not right

I have both the 68 and the 69 does not then see how to modify it ...

since where I have been able to help I have helped you ... now you have to do is modify the mpc file and write it ...

if I put the driver 69 hp,
take, for example, the curve of injection there are numbers in the negative
and also on the advance curves.

Could you post a screenshot where I do see that the drivers you're using
or what values to display?

You are right the.maps.are not all right

This I know...
the curves are all in the bottom and I found them all
I tried to figure out what they were,
for the moment, I seem to there are several curves IQ
but I can not find the curves for the lambda and the curves to turn off the second lambda

Eh the hell I don't know

Let me know if.solve
