Baseline for HV Battery SoH Performance

[ciaranob]

So let me ask a question (even if a bit off topic): I have an OBDLink CX (110 €). It works both with CarScanner and ABRP but when I insert it in the port while in Park I get a red message on the dashboard ("high voltage system active", or something like that). I read in another forum that this is normal. What do you think?

Mine and others do the same - just a PCM reaction to 3rd party tool but. Nothing to worry about - clears immediately on removal of the OBD2 and does not effect the tool operation on any way.

no worry at all!
it's the gateways reaction to any CAN message sent at that OBD port so it's popping up as well at the Porsche dealer with official PIWIS tester!
(BTW: it's the dashboard, not PCM )

I assumed the PCM sent the msg to the dashboard - ?

PCM is not involved when you query the CAN bus...PCM is only one of dozens of ECUs on Taycan's many CAN and other busses.

I use this the ($60) Vgate vLinker MC+ Bluetooth OBD2 (iOS and Android) which is rock solid and plays well with the free (or min paid) CarScanner App:

Shoulda bought that.

Got a Bluedriver because of the rave reviews. Turns out it is not compatible with the Taycan.

Yes - blue driver excellent and had it for my M4 I sold earlier this year but indeed not yet compatible with Taycan.

Even cheaper direct from the manufacturer ($47):

why the MC+?
I'd not spend more than 30 bucks for a China BLE dongle.
If you like to invest more, buy the fast OBDLink CX and support your country's stuff.

I don't generally critique peoples preferences/choices but for me the MC+ has greater vehicle coverage (including an broader range of older models) than the CX, is faster and with a few other differences but yes either one is entirely sufficient depending on your needs. The CX is usually ca $80 here in the US.

PS: can compare both here: https://www.obdlink.com/products/obdlink-cx/

the MC+ you linked is a chinese clone! Are you aware of that?

Has anyone looked at Open Energy Monitor? The project has something called the Open Vehicle Monitoring System. Wonder if this is an alternative to the vlinker? https://shop.openenergymonitor.com/ovms/

no it isn't. way more expensive and you need one of the few supported cars to get some benefit.

please keep in mind:

ELM327 is the common standard, most dongles are based on.
The original is from Canada, they built and specified a serial to OBD/K-Line/CAN adapter on top of a PIC controller and that protocol is now standard.
Usually there is a USB or Bluetooth interface plugged at the OBD to serial chip to useit via cable at a PC or BT with mobiles.

ELM327 was heavily copied by chinese "vendors" after a leak of the PIC firmware etc. , which would be enough stories for a Netflix Miniseries.

Today you cannot but an original dongle, only chips to build your own, but even this is probably not possible anymore:

there are only a few vendors that really engineered new ELM compatible devices and extended their capabilities and speed.
One of them is https://www.obdlink.com/ and if you check their devices you will notice that the dongles from vlinker look very similar, but guess what?! They are chinese clones!

What app are you using with the vLinker? I downloaded Car Scanner but it's not working.

Works just fine for me - did you chose the Taycan profile built-in when setting up?
