Skoda Fabia 1.9tdi vp pump 65hp _engine electronics edc15VM
I have a problem after writing the file,it doesn't matter if I did a remap, egr or dtc or just change a number in some card, the car starts turning on and off, as if for an immobilizer. It doesn't matter what the file, galleto, kess, mpps, v18, v21 will be written with , in 16, or what will the check sum be calculated with, the problem is the same, has anyone encountered this problem by chance???

Man, do you think that if there is a problem 109 I will write here ................A little more seriously, I wrote that the car only has a problem with a MODIFIED file

Maybe you can move the wrong maps if the original is ok?

No matter what is touched on the original, the car won't start, not even one percent driver swish or torque or smoke it doesn't matter what it is.Тhe car starts to turn on and off...

Hi, what did you read first? What device. Did you upload the first changed file? Or another tool? You can try to find another ori file and do a recovery with kess and then see if car start

I tried everything I could think of...including what you say, I have all kinds of devices from Chinese kess, mpps, galetto, to autotuner

Skoda Fabia 1.9SDI test checksum

File in post#1 is Original, checksums are original to car

Post your modified file and we can fix the Checksums for you... problem solved...

something is from the tuned file wrong touched ,not possible not to start with chks ok ,but you maybe maded checksum with other tool then and kess make too and car no start
post ori and you tuned files to see what is wrong

Colleague, my respects, but you obviously don't read what was written above. I repeat, whatever is touched in the vtv file, even if the gas pedal or torque is touched with one unit, the problem is still the same...

Please extract the ecu to the table and open it. I had it in the Vw LT EDC15, there was a stand mounted in the ECU and it ~~~~ed up the job. It is possible to read and write after OBD, but it does not enter the entire file. Regards

Correct, because you did not correct Checksum before writing to the car.

This is not a problem with Chks. Because if the sum was damaged, there would be no engine control and no communication with the ecu via obd. Tell me, what was the first thing you read when the Tsar arrived? What tool. I think it corrupted the eeprom. View immobilizer status. Because it may have corrupted the synchronization. Since you uploaded ori file what was in the car and then the same. It's not Flash's fault. Try to do immo off and see then. If not, find here on the flash forum about this ecu number. Flash kess using the recovery function. And the car must start.

It looks like a cks problem because on the original file the car fires, I think you could try to improve cks in winols and then try.

Let me get this straight.. If car runs fine with original file and doesn't with modified then either something is touched with shouldn't have been in maps or checksum is wrong.

EEPROM is not touched for tuning.

That's ok. I thought that even after uploading the ori file is the same. Since the ori car file works ok. There is no topic. But if there was a problem with the control sum, this ecu stops connecting after obd and there is no engine light. And that is 100% certain. So there must be a problem in the processing and changes in the maps

And you can write what you need to do in this file and one of us will do it with improved chks and you try it?

make a file we can test no matter what changes, stage 1 for example or just move the pump voltage....

You obviously don't read at all, the checksum was calculated manually, with Vagedsuite, with winols and with swifftec.....
