What do you think the Porsche Piwis Tester II from China?

It’s a grey market Porsche Piwis 2 It’s likely real but not with online capabilities. This means it’s a probably a copy hacked to work offline only. Typically a real PIWIS’s hard drive is cloned, installed into a similar laptop, and mated with the Bosch OBDII hardware or a Chinese copy of it. To do remote coding or enabling things like sport chrono you will need to log onto Porsche’s network with a valid user id/password. You will not have this capability. The modules listed require online access. I’ve also seen these grey market sellers offer their online logon via remote access for 24 hours for a fee of course ($250?).

A buddy loaned me one to play with when I retrofitted TPMS into the car. There are definitely more features than Durametric Pro, but not a huge number more. I accidentally disabled sport mode with it, and needed to see the dealer to get it reenabled because I did not have the online access, and wasn’t about to pay more than a dealer visit for remote access from Asia into my computer. But I did get the TPMS system programmed properly, even enabling summer/winter/special (track) tire settings.

I’d say Durametric Pro covers about 80% of the same things without the online access. There are some small items that PIWIS on OBD2TOOL can do better, and in some case beyond what Durametric Pro can do – mostly on the coding options side. Putting the grey market piece aside for the moment, I concluded Durametric Pro was enough for me since I already owned it. But if I didn’t and want to spend double I would consider it. Again, putting the grey market piece of it aside…

Can I use VAG-COM to roll back my electronic odometer

1.Is there anything else I need to make full use of VAG-COM?

Yes. A good Factory Repair Manual containing the the VAG Scan-Tool procedures for your car. VAG-COM is a tool, not an on-line service manual. We could not possibly document everything you can do with it in every year and model of VW/Audi that VAG-COM can be used with.
For US and Canadian VW and Audi models, the best source are the Official Factory Repair Manuals by Robert Bentley Publishers. Please note that Bentley also has some publications called “Service Manuals”. These tend to be less complete than the Official Factory Repair manuals and are not recommended for use with VAGCOM 18.2.
Since the above Bentley Factory information only applies to US/Canadian vehicles, if your car is European-spec or from the rest of the World, they may be of little use to you.
For Rest-of-World VW, Audi, and SEAT manuals, check erwin-portal.com
For Rest-of-World Skoda manuals, check skoda-haendlershop.de (currently German-only)

2.Can I use VAG-COM to roll back my electronic odometer?

No. A brand new instrument cluster (with less than 100 km on it) can be rolled forward, one time only. Of course, this assumes that the instrument cluster is “diagnostics capable”. Not all instrument clusters with electronic odometers are.

3.Can I use VAG-COM to “Flash” the chip in my ECU?

No, we have investigated flashing, but found that there are several different methods of encryption for various VW/Audi vehicles, as well as delicate licensing issues to overcome. Therefore, we do not intend to pursue flashing any further at this time. You cannot alter boost, timing, fueling, rev limiter, or speed limiter with VAG-COM. You should contact a chiptuner if you wish to have those parameters altered.
