Mini vci fw 2.0.4 vs COPY mini vci fw 1.4.1,which one is better

Any difference between original and clone Toyota TIS Techstream cable?

MINI VCI fw v2.0.4 and fw v1.4.1 differs in PCB design, protocol, and some functions.
if you would want to reset immo, or make customization to cars, need at least 2.0.4 FW
with 2.0.4 FW there is change in PCB, as it support VPW, and has extra security chip
on the other hand, all these simple clones with 1.4.1 FW support only CAN and K line
VPW protocol is unsupported in 1.4.1 FW, and there is no parts for it on PCB


In short, Xhorse-made Toyota mini vci v2.0.4 supports VPW protocol and IMMO RESET, customization, but copy mini vci cannot perform the functions.

Rework Ktag Kess V2 pcb hardware-work no issue

Share free solutions of reworking clone Ktag and Kess V2 ECU tuning tools to work completely like the genuine.

Original PCB in the photo ... use if you have any other issues.

Replace by quality components.
Thx button would be nice.

Free for everybody!!! No more payment for this!


Part 1 - KTAG hardware rework

Ktag before rework:



KTAG hardware rework solution:



k6b = BC817-25 SOT-23 (in some originals)

All capacitors should be replaced with the exact same one but new

Part 2 - Kess v2 hardware rework

Kess v2 pcb before rework:



KESS V2 rework solution:


Transistors to use :

Murata filters:
NFE61PT472C1H9L (connect ground for all of them)

1uF - 35V
220uF - 10V
10uF - 16V tantalum

Fill up all holes from side to side
Use photo as reference if others components are different

From sally:

KESS V2 is a ECU programming tool that is perfect for OBD use, while KTag is perfect for Jtag, BDM and all the Boot application (tricore and ST10).

With KESS V2 you programming directly through the OBD port of the vehicle, while with Ktag (Ktag 2.13) you need to take apart the ECU and open it, after you can make the read/write operation.

Many ECU has the advantage that can be read and write from OBD port (so KESS V2 is perfect), but there are lot ECU that need to disassemble from the car and open and this is the case for all the ECU that need to be programmed with Jtag, BDM and Boot protocols, so KTAG is needed.



Foxwell NT510 multi-system scanner reviews

Have used Foxwell NT510 for BMW repair job for more than a year. Here is what i did with it, some successful and some not...

Foxwell NT500

1999 540iT

2003 E39 M5

2003 X5 E53 4.6is

well beyond a peak code reader for specific BMW codes on 3 BMWs E39 M5(2003), X5 E53 4.6is (2003), and 540iT (1999) ---ok


2000 E39 M5:

communicates via the obd2 plug in the cabin, read TPMS codes ---ok


2003 e46 325xi:

read codes from TCU ---ok


2004 X3:

read and reset airbag service light ---ok

have an intermittent airbag service light on 2004 X3 that BMW service cannot track down as it clears from memory before I can get it in for service


2006 BMW X3:
find 2 misfires because of bad plugs ---ok


2008 BMW E93:

register a new battery ---ok


2009 BMW E82 135:

scan for ghost codes, and any other stored codes ---ok


2009 535i N54 engine:

allow to alignment and calibrate fuel injectors ---ok


2009 BMW z4:
diagnose and find bad HAL sensors stopping the roof from retracting ---ok


2009 bmw 335i (American):

do battery registration ---ok


2010 335i:

code new injectors ---ok


2010 BMW e88:

reprogram of injector values and Engine idol speeds and it can be used on it ---ok


2011 E90 328i LCI model:

re-program the Speed Governor ---ok


2011 335d:

clear the error code for halos with proper resistance; reset "Right/Left Cornering light" warnings caused by after-market halo installation ---ok


E92 M3:
perform a throttle actuator adaptation ---ok


2012 BMW F10:

reset SAS and the Airbag/seatbelt light also can modulate the e-parking brake on F10 to enable a rear brake job with rotor replacement ---ok


BMW F82 M4

provides sensor data from the oil level system ---ok



OBD1 cars will require adapter ES2992111 to perform function, available features will be dependent upon the cars abilities. But not all features are compatible with all models... Sorry for i forgot the make notes of this


Also, i got some failures on this scanner Foxwell  NT510:

2007 BMW z4m roadster:

cannot remove the top rpm limiter on a BMW z4m roadster 2007, performance tuning software is required to remove top speed limiters


2005 BMW x5 4.4i e53:

can't retract the calipers on a 2005 BMW x5 4.4i e53. The E53 does not have electronically controlled calipers.


O2 sensor reading and clearing:

Can read and reset O2 sensor readiness codes but will not code them off.


In short, i have to say, this NT510 scanner definitely gonna happen to repairing work. Easy to use, only to follow the screen instruction; even if green hands use without issues. Helps me a lotttttttttt
