I am looking to find the best tool for med17 ecu, I was looking at the kess v2 is there any other tools to flash therw obd2 port?

What's the name of your tuning company?

You forget about MED17 to read it by OBD.


Even original devices can not read all of the MED17 after OBD.


The safest way is to program these drivers in boot mode.
If something goes wrong with MED17 during OBD programming, IMMO flies into the air.
MED17 is programmed on the table without any problem.

Okay what should I order to bench read/flash med17?

Order from China? :P

Which MED17? VAG MED17.5?

Most tools will do VR and flash OBD for VAG MED17.1/5/5.5/etc..

Best OBD tool for VAG? Probably CMD

Believe it or not, there are hobbyists who want to flash their own car.

1. There is no need to read anything ever - you can use virtual read. You can never damage anything via OBD that is not contained in the frf (uds) / sgo (TP2.0/KWP) container, because this container contains all OBD flashable data.
2. Boot mode reprogramming of VAG MED17 is like 2010 year stuff. I don't see why you would ever do that when you have access to correct tools.
3. Absolutely nothing happens with immo. Immo needs to be only authenticated for starting programming, and it does not need to be re-authenticated until programming is complete. If any programmable section checksum is invalid, the ECU will go into bootloader each and every time. So absolutely NOTHING happens if you program MED17 with a valid file and pull the plug in the process, you can always restart the write.
The only thing that can ever happen is if you program a file with code modification or badly changed map axes where the checksum is correct, but the changes aren't.

But I guess, china tool copyshops still go like "ZOMG YOU MUST DO IT IN BOOT ONLY !!!111".

As for decent tools, there are no clones that will do everything correctly, especially you are going to have a problem getting original files.
Some original tools that work:
* CMDFlash
* Original Kess
* Original New Genius
* X17
X17 and CMD have the best VAG coverage, because they do most gearboxes too, but X17 programming is super slow because their hardware is very bad. CMD is fast.

Some tools that are cheaper and allow to write vag MEDC17 OBD:
* Ecuflasher with VAG module, though I am not sure exactly how getting original files works with that
* Original MPPS.

phil has raised the price of mpps + tpsg significantly over the last 6 months or so.
it really is not any amount cheaper than buying a cmd or equivalent.

oleg (pcm guy) has some of the best all around cost vs support vs it actually works.

mpps bricked med17.1.21 (bl obd unlock patch code) so not even able to reflash sgo. pcm flashed it perfect.

Then he has 5-6 different cars, all different ecu/ engine types.

Whoa,  PCMFlash for VAG MED17 for $207, Simos 8 for $247?  What's the catch?

I don't think there is one.
You can just buy per protocol, but there is nothing new or revolutionary in there. Just copied protocol from some mainstream tool and sold for less, simple as that.

I believe I'm gonna pull the trigger on the Simos module so I can start working on my B8.5 S4.   $324 shipped.  That's a dang good price if support comes with it.

Yes, PCMFlash is very nice to use. Haven't tried their VAG stuff yet, because already have X17 and Kess.

The only "catch" is its just software. You'll need your own J2534 cable. Also, pretty sure it doesn't do TP2.0, just UDS (for MED17).

I already have a J2534, so it's nice not having to pay for extra hardware.  It looks like there are two separate MED17 modules, one USD, the other TP2.0.  I pulled the trigger on the SIMO module.  If that works well, I plan on getting MED17 module as well.

This Vag med17 is here in Canada,  and I'll see if I'm able to source some of them tools mentioned

The ecu I am trying to read/write is a med17.5.2

PCMFlash worked to flash the Simos 8.5 ecu in my B8.5 S4.  Virtual reads only. 

I can tell you that it will at least identify MED17 using TP20 on CAN.

I used the genuine Tactrix OpenPort 2.0 J2534 interface with the PCMFlash software.

Does the virtual read contain anything but the cal area?
Is the data outside the cal area encrypted or not?

pcm uses full flash for simos8. or at least, more than calc area.

I am looking for good tool for vag med17 and will get into the Simon's ecu fir golf r  soon as well

Take one for the team like I did, and buy the TP20 module and try it out!  Report back!

your team is playing catch up.  :)

lol, my team is "team hobbyist" aka "team doesn't do this for a living"

But yes, you are correct.  Maybe someday I'll be a big shot too.
