Hi, I am beginner in this ecu world. I would like to tune my car but i don't know if it is possible over OBD port. found some stuff online that it is possible with mpps V16 clone but I am not sure. I need to buy tool for flashing so this is the reason why I ask, I would like to buy some kind of clone, obvious reason $$$ :)

easy all car with edc17cp14 before 9/2009 you can write over obd no problem . same with softwareupdated ecu the tuning protection is everytime the same.

If I understand from this vcds scan is visible that ecu is flashed 17.09.2014. does that mean tuning protection is on now?? which tool do you recommend to buy ??

look at the car build. is it before 9/09 you can write . the flash date is only last update
car before 9/09 you can write over obd
car before 9/09 with update to 2017 you can write over obd no tp active
car after 09/09 you can read but write is luck :-) only boot is safe or ori tool
best buy kess 5.017 with 2.22 you can do many cars
and a k-tag for tricore

My car is 2008 so it is perfectly safe to read and write...i would like to buy mpps v16 clone because it is cheap and don"t neeed it for other cars just for mine. To sum up things I can buy clone of mpps v16 read and write perfectly safe with it over the obd port ??

Than buy kess v2 with old Firmware its better ;)

Can I mess up something just with reading ?

You'll only mess something up if your laptop or car battery dies.

To be safe have laptop plugged into mains and if have one to hand, your car battery hooked up to a charger pack.

I advise you not to write this ECU obd safe method is to write in the boot with fgtech

thank you, than it will be fgtech or kess...but I am not happy, for every flash you need to open ecu :(

Use search button or google, you will find how to open ecu without damage :) It's not a hard work, only need some time and patience

galletto v54 is good for beginning, you will find it for about 50$, not a big deal

i never use obd r/w for edc17

You dont Need Open this Ecu :) you can Write with kess No problem. Galletto is Not so good it kills sometimes the eeprom.
I'm 100 % sure that work if Not i repair your Ecu for free :)

With the NOx update an such car TP is also not changed.
So i can write cars before 9/09 with NOx update also over OBD

Yes u can i have test many cars :) all Cars that have No tp get no tp with update

that is useful info ;) can I get full backup over obd if something goes wrong or do I need to have backup from bootmode ?

You need bootmode backup

Mpps 18 good eu clone can safley write obd edc17 with tprot. Ive done many. Only cheksum calculation takes about 30 mins. So dont panic just have patience. Writting another 15 min.

But indeed the safest way is to bootmode. ☺

The safest way is to buy geniue tool (I use KESS V2) and programing that ECU over OBD...

All edc 17cp04/cp14 and much EDC17c46 and 17cp20 will go now by Virtual Read

I have clone tools to, like Gv54 EU but I never tried EDC17 on OBD, In boot mode 99% works perfect, but one time kill on boot edc17cp14!!!

so you would happly write to 2012 car with mpps ? edc17cp14

so you would happly write to 2012 car with mpps ? edc17cp14Don't try to whrite ecu edc17 cp14 over OBD after nox update, I tuned my car with kess v2 ( golf 6 tdi 140 hp 09.2009 ) first time no problem all over OBD work perfectly, after few years I have update this car on vw service after nox problem , after update tuning lost, back home I have tried to read with kess , no problem but now kess says , after id ecu that I have to apply patch with the tool k-tag in order to whrite file back over OBD, after update don't work OBD without patch, ecu opened, patch with k tag and now no problem over OBD!

thats wrong ! Kess say ecu is protected because he check Softwarenumber and this is over 50000. than say kess ecu is protected but it isn’t . All ecu with tp <7 have this also after update . And u can write over obd

I normally with tprot,read backup with new trasdata,I can apply a patch into internal flash tc1797 to un protect it, and when I reflash patch, ecu is written vía boot.
I can test that car starts and then work everytime with MPPS.Once patch is applied and unprotected,you can always work by obd

With OBD reading project,you don't need calculate RSA protection checksum.

yeah he say only to clone, orginal say change protocol to XXX and download vr or read ecu.....

Hi guys sorry to hijack this post , did somebody from you have to sell one used infineon tricore module for kess v2 , only module , no need for cables or something else , preferably from Germany but Also Europe it's ok , I need one original not China clone , or eu clone , if somebody has one to reasonable price let me know on pm https://uploads.tapatalk-cdn.com/20180127/d1fa7d36d827153aadb09073ee6ab584.jpg

No. But can write frf file with original mpps, not sure about clone

Is there any news in this regard? My car is from 2008 (CEGA EDC17CP14).

Can anyone confirm that it works via OBD?

Can I restore the ECU in an emergency with KTAG without having a BDM backup?

hi, I confirm you can do over odb with kess V2 , in case of problem i did a full backup before use odb, but I write and read more than 10 times and no problem.
Just use power supplier battery to have always a good voltage !
I had just to remove mechanical protection which was on the ECU to avoid chiptuning.
Thanks to ICEZRO2010 , who assited me for the test, you can trust him !

Thanks for the fast answer! Did your car have the emission update? You used Kess v2 clone, right?

Hi guys!

Im digging it out from the hell this thread!
Its 2021, I think its good time to make some summaries in this thread - speaking about KESS 5.017 EU RED PCB China clone [2017 pcb version and up]

What we know for this moment?
Cars before 09/2009 also with NOx Update, can be write by OBD.
Cars After 09/2009 cannot, because of high level TPORT or you can try on your own risk.

My question is other... where/when to you use protocol 198 and 501.
What determines the choice of this protocol? SW wersion? After 5xxxxx 501 and 3xxxxx 198? And where we can use VR read to write - on 198 protocol and 501 or only on 501 or it depends on SW version 3xxxxx or 5xxxxx? What version of kess the most reliable is to work with it 2.23 2.47 or newest 2.70 with repaired something to CP14?

As we all know 198 gives you can read and write, 501 only write.

We know also that with 501 protocol having VR we can also write CP04/14/20, C46 and even [at least I heard] C64/74.

Next info we know we cannot mixed read file from 198 and write with protocol 501. And also even if protocol 198 let you read the car if you have TPROT >7, trying to write this file with 198 or 501 protocol will ends up with bricked ecu [not death at all, but it stays in programming mode].

Someone wants to answer me about the above question and may be add some from yourself?


EDIT Ad. "my questions":
OK.. I figured it out myself, so in short:
- protocol 198 - you can read/write with him, but he's faulty and not reliable on some ecus after 2009 - and this is why Alientech made protocol 501. With older ecu before second half of 2009 this is 06/2009 or maybe as was said above 09/2009, but not newer. Of course you can try to read by this protocol newer, but YOU CANNOT WRITE and this is only "data only" read so useless to WRITE, because you need to have VR read on newer ECU. Older before 06/2009 you can try read and write with this protocol 198 and thats it, but Alientech in informations of this protocol left a statement which is the that protocol is not reliable. Known problem is that on this protocol write CAN stop on 99% and lock your ecu in programming mode [its rather on newer ecu, if the SW is other than 10733xxxxx and if the SW is 10735xxxxx it can be still without TPROT, because of NOx update, but... be aware, because he can (but he mustn't) has got a TPROT now and YOU CANNOT use protocol 198 in this moment].

- protocol 501 - repaired protocol, but... for this moment you can ONLY WRITE, no read possibility. If you have VR you can use this protocol for older and newer ecus and moreover if you have 2.70Kess - in car selection - you will no longer see and can choose protocol 198 [deprecated and not recommanded, but still you can use it if you want - in Protocols section, he's still available to use in older ecus or any other fantasy].

I think this is all from my investigation and may be it helps for someone.
Soo... still to be honest the most reliable is bootmode, but... if you have certain/good/right/... VR to your car; with protocol 501 and good battery charger - you can WRITE your car (even if your ecu have higher level of TPROT) with success [you should know its always risky and even if you have genuine tool].
