Can someone tell me the difference between Kess vs Ktag, I hear one is better for Toyota, Honda, Nissan ect ect and the other is better for Renault, Citroen, Ford ect ect.
I dont know how true this is so would like to ask you people

Thank you

Kess is mostly for working over the OBD Port in the Car. For newer cars from 2011 with EDC17/MED17... ECU they archieved the Virtual Reading, so you have to make ID of ECU and get the ORI File from Alientech (not for clones!) or from your Tuner. Then the Ori file can be modified and you can flash it over OBD Port. You only have to sit in the car and flash a file For old Diesel and Fuel Cars till 2008 (EDC15/16) you can also read the file and modify it.

It is easy to do, but if something goes wrong on the newer cars like EDC17/MED17, checksum error or wrong calculation you have some problems to fix it. Like Car not starting or error in ECU (e.g. flash original Soft with original Tool) Not every car can be made with kess!

KTag is the safest and also the most dangerous possibility With this Tool you work direct at the ECU Board.

The dangerous thing is to get the ECU from the Car and open it. It is glued with some black silicone, so you must make it hot, lever open the case and also cut the glue. When you harm the board inside, with the knife or with a screw driver you are in big trouble. I first got 3 cheap broken EDC17 ECU's on eBay to learn how I can open those ecus. Now i can open them so clean, that no one can tell if it was opened. The first one was a big fail, so you better try first with some cheap broken ecu from the net.

With KTag you can read direct over tricore boot from the board and have a good backup. If something wrong happens, you can put back the backup and no one can tell directly that there was a modification or you can fix a not starting car. More cars can be done with KTag so you see, you need Kess and KTag

I attached some pictures for you to see how dangerous open the ECU for KTag can be.

1. 1 of 3 Broken ECU from eBay - First ever opened ECU in my life without patience
   
2. 4th ECU from Friends car.
   
3. Now normal opening conditions - ECU already opened and closed after tuning.

Thank you for the detailed info. I have here as a test vehicle a Peugeot 307, 2.0hdi that I would like to remove the DPF, what tool would be used on this and would this be a OBD or direct read ?

Thank you

HI,
With year of this Peugeot?
This car do it safe with Kess over OBD.

Does Kess/KTag also remove/transfer IMMO data as well. Need to flash ECU for Jetta 2013 EDC17C46, but cannot complete as stuck on "Immoblizer is not enabled" error when trying to flash via ODIS E. Thanks.

You cannot do immo via KESS, but yes with ktag, or with some other prorammers...
Kess reads and writes only map-s not immo, and ktag reads and writes both, if immo is on EEPROM that is on ECU, but for some cars immo can be in flash, or in eeprom on BSI, or IC or even on board near to key...

Hello Guys,

For cloning an ecu... Is it possible with kess if obd read is possible? Or only with ktag?
