Question:
Which i can use for diagnostics xentry and inpa/ista at least and for
programming vediamo, monaco and ncs expert? VXDIAG
VCX SE or the new SM3 (Scanmatik 3)
Scanmatik SM3 Pass-Thru adapter is a successor of SM2Pro adapter with CAN-FD
and DoIP protocols.
The new scanmatik 3 (looks pretty much the same as scanmatik 2 pro), but main
difference being the introduction of CANFD, DOIP, wifi instead of BlueTooth,
faster USB data transfer speed (from 12 mbps to 480 mbps, they changed the usb
chip/drivers it seems), and the auxiliary cable now comes with the basic
package.

-
Compatibility:
- Both units work as J2534 passthru devices for software
like Benz Xentry, BMW ISTA, and
others.
- Both support tools
like PCMFlash and BitBox for
ECU reading and writing.
-
Features:
- VXDIAG VCX
SE supports DoIP but
not CAN FD. For CAN FD, the VXDIAG
VCX FD model is recommended, which is cheaper than the
SM3.
- VXDIAG VCX SE supports
both Vediamo and DTS
Monaco engineering software, while the SM3 only
supports DTS Monaco.
-
Pricing:
- The VXDIAG VCX SE/VCX FD is much cheaper
than the Scanmatik 3, with the SM3 costing about twice
more. On aliexpress sm2 pro costs like 50$ and sm3 450$.
-
Issues:
- The SM3 has issues with K-line
communication (e.g., problems connecting to PSA
Diagbox and flashing ECUs
like Med9 and EDC16),
whereas the VXDIAG VCX SE works fine
with Diagbox after license activation.
- SM3 has slower connection times and issues in Vediamo
coding and DAS operation.
-
Recommendation:
- If you already own an SM2, upgrading to SM3 might not be worth it,
as SM2 Pro still receives updates and new
features.
- For users needing to work across multiple brands, the VXDIAG
VCX SE is a better choice due to its lower price and broader
compatibility.
In summary, VXDIAG VCX SE is cheaper, more
versatile, and better suited for users who need support for multiple brands,
while SM3 has some technical issues, especially
with K-line communication.
