EDC17C46 probloems

[Tosi79]

Hello!

We have a problem with a Yeti ECU EDC17C46.

We read it with V54 Galletto without problems, first we read tprot v08 and then in boot mode we can get the ori "all read" file 2.112 kb. We loaded the remaped file based on the original, and the car starts but it stops suddenly. It don't seems a checksum fail because the car try to start.

We loaded again the ori file we get, and the V54 don't show any problem to write it again, but the car is doing the same, it starts but then stops, we have conection via OBD with VCDS and it shows some Injector fails that we didn't had.

We are crazy with this car, we write about 7-8 times the ori file and remap file with no succes, we are thinking that maybe the V54 is not writing properly. Or maybe the first read of the file was bad, but the remap company has confirmed that the ori file is ok.

Could someone please check the files for me with winols?


Any suggestion? We have no more ideas to check.

Thanks in advance.

i had same problem with edc17c59 from opel ecu.Was pcb failure after opening.Try to start without the aluminum box this side with screw i believe that will be ok.

[Tosi79]

Thank you at all, I'm trying your files, I hope to solve it. But if it was a checksum fail the car don't do anything to start, isn't it?

[Tosi79]

I test it, but It don't start, but now the cooler fan is starting. And it don't show any engine fails on dashboard. I'm cheching with VCDS.

This file takes 22 minutes to write, and the others just 5.

[Tosi79]

No advance, anybody has more suggestions? We tested all your files but with no success, but it's true that the car is doing some different things.

With these new files the car stays with the cooler fan started, and we don't have OBD diagnosis connection, and before this file we had it.

Any suggestions? The PCB seems to be ok, and connection to read and write is really good.

No matter what you think... the engine MUST start and work with the original file just fine... IF THE ECU IS OK PHYSICALLY!!!
I am not happy to said, but this always happens when someone want to earn easy money (or save it) without the right tools and/or knowledge!

[jurebv]

try to write with other tool, if still problems then ecu probably damaged on opening to boot

[Tosi79]

Thanks for your help anyway. Bad news if we have to change the ECU... There is any way to ensure that the ECU PCB is damaged?

[vitaliyl]

the dealer will tie without opening
or use the bootloader which will write without opening

[Tosi79]

Just wanted to inform that after a full check of the ECU, it is in good conditions.

As the technician told me, the problem is that the ori file we reed first time is with some errors, and for that the remaped one is also bad.

I have from internet the ORI file in FRF format, it is possible to write it back with Galletto v54? It is necessery to convert to ORI?

Thanks!

[vitaliyl]

not possible write FRF with galletto, use ODIS or VCP

[Tosi79]

And it is not possible to extract the ORI file from the FRF file to write it with EOBD2?

[Tosi79]

Is it possible with VCDS ?

write via OBD edc7c46 china galetto? - not possible :)
maybe write open ecu & bsl write

[vitaliyl]

Is it possible with VCDS ?
it's fantastic

[Tosi79]

Then it is possible to load the FRF original file with the VCDS cable? I cannot find information about it. If not I will try to find a VCP cable.

VCP, I think only...

[vitaliyl]

VCP, I think only... or passthru j2534 + odis

[caja88]

Got it working?

[bobolin4o]

Got it working?

Probably - not...

Why is your ori flasch file not 2048kB?
2.112kB is like backup or flasch + eeprom.
