- In this video we repair a fake Tactrix Openport 2.0 OBD dongle that doesn't power up off of the OBD port.
There isn't a schematic as such, but I have pasted a link to how it was wired up below, as well as a link to the Buck Converter on Aliexpress.

Its much easier to get it working... just replace R1 to 47k ... so its working fine on OBD Power. No need for extra step down converters.
We replaced r2 as its part of the potential divider with a 56k resistor and the DC-DC still didn't work - the output remained the same. Really appreciate the input but its done now and works, but I'll pin your comment so people can try that first and then if that doesn't work they can go all out on it and do what we did. Thanks for the info!
Is the device working? Have you tried reading or writing firmware from ECU?
It doesn't work
I tested R1 with 47k and it worked, thanks! But I found the voltage a bit low. From calculation ideal is 52.5k. I installed a 51.1k and voltage is very close.
good morning which smd reference
Just got one of these from Tork motorsports for my Veloster flash.. and no Lights show. Based off this video I have t he same exact counterfeit too. Great.
If you don't have the skills to de-solder the component as mentioned. You can try to use a little powerbank together with the USB cable connected to the Openport.
Hello! Thank you for this video, it’s fantastic. I need your help, when I’m welding the orange cable to the pcb I lost the tinned pcb… 😭 where can I weld now? Because I can’t weld in the same site. Thank you so much 😊
Does your edit solve a specific problem?
Full function? Thanks
do this one work for most of the ECU
I have 2002 Isuzu trooper 3.5 v6 DOHC I want to tune it. I really want to know this will work on it or not before ordering it
looking forward to here you soon
best regards
Was I lucky? Mine works flawless on my 2001 wrx? have flashed partial changed maps and completely 100% different maps, Always works perfect and logs perfect, But I will be buying a genuine just to support the company as this genuine is extremely cheap compared to other tools in the tuning world.
RCJ Tuning My boss has never had an issue with his and he’s flashed maps fine with it multiple times. He didn’t deliberately buy a knockoff, but that’s what the Seller sent him...
@@the_equalizor I just checked and although mine functions perfect it does not light up off obd alone, only lights up once connected to the pc.
Hi, Thnks for the video, mine doesn't turn on after flashing an ecu with ecuflash, it was fine for about a year, it doesn't turn on with usb but has voltage on board (4.8v). I tried an other one with ecu flash and it flashed the ecu once and now it's same as mine. Do you have any idea?
Hi will it be able to read and write SIM2k 341 ECU?
Will this clone Flash Toyota ecu's through "calibration Update wizard"??
i want consult3 software do you help me?
whats on this sd card? i bought mine couple of months ago and already lost the sd card now i dont know what was on it
hallo is possible deactivate the connection at internet only for the Tactrix ? need have support by teamviewer...... thanks
Can I use same DC to DC convertor without removing any components
please FIX the sound on this video, i can barely hear you speaking with my volume sky high, otherwise great video, please post more 🙂
Hello! Do you have a "chinese" firmware for LPC2387 MCU?
Replacing R1, R2, R3 resistors makes sense only when LM2734 is functional. You spent time replacing resistor for nothing, it will not do anything, because SFEB chip was dead. The video is great anyway, Thanks.
How testing SFEB
Thanx for it. Say me please, what is a scheme you use for upgrade? Where i find this scheme? Thx)

WooW! Thank you very much!
I already killed 2 chinese copy units. Good thing it was after writing the data to the ecu. Already bought the original tactrix. I'll try reviving the 2 old defecrive ones after lockdown.
Actually they are killed (destroyed) remotely on purpose by the makers of Tactrix in the USA.
@@bn880 for real?
@@darkcashyz yes
@@darkcashyz There are modifications that can be done (not easy) to pull up the write pin on the MCU to prevent it. Otherwise don't allow internet connection when connecting the Tactrix to PC.
@@bn880 so its something on the latest ecuflash or internet also .. I think its more of the latest ecuflash has some hidden kill codes > ? has there be any fix after its been killed or some repair ? cheers
Try differents USB ports because, I get 4.84v without any modification, ONLY changing the usb port on my laptop (usb 3.0 controller in expansion port). I try in another USB 3.0 and I got only 4.54v. If I use a charger with only 1A the volts drops to 4.33v...with 3A charger up to 4.54v, but only got 4.84v in this USB 3.0 controller (RENESAS).
what happens if your getting lower voltage on other usb ports ? it wont read properly?
Logging to SD card was not working, the power supply from the OBD did not work. Successfully repaired by changing R1 from 10K to 51K - I had to ask someone with equipment.
Yes, a couple of people have mentioned this fix and thats useful to know, but doesn't apply in our case as we changed that already. The DC-DC circuit was faulty on ours.
I confirm this works. (there are other fixes that can be made, like adding a 100uF cap on the regulator input, and a few other resistor values can be corrected as well like R3, R31, R19 , google it a bit)
Hi, I bought mine and I think it broken, when I'm connecting via my laptop USB no more light show up, first time I think I'd see light shown. Is this solution going to help me ?
Hatsanat Srianant Does it light up when plugged into the OBD port?
@@the_equalizor No, but first time I did not see any light shown when connect to my obd too (only show light when connect via USB side). Thanks for your help 😃
Hatsanat Srianant okay so are you saying that it doesn’t show any lights on usb and obd? That could be the voltage regulator has gone bad then. Iirc the 12v and usb 5 volts end up going to a 3.3v linear regulator. I’d be checking the voltage going into that (5v I think) and then it should have 3.3v coming out. If you google the part number of that regulator you’ll see which the input and the output pins are. I think it’s the 3 pin device behind the sdcard socket.
I've had 2 fail, Rev. E. fail after 1 read 1 write or less. Are they repairable?
I've got two of them and ended up buying a real one. Every time after unplugging the adaptor from the car they fail.
This thing is good for logging and reading ecu but not good for flashing maps. It can flash but Is not consistent. So if you don't want to mess up your ecu flashing maps into your ecu don't use this for it. Only good for reading and logging
Hi.! Does xentry C4 C5 also work with openport 2.0
Only PassThru one, not an OpenShell
Work just fine with DAS and Xentry
nice video.. but i need your help please, Can you help me install my Tactrix openport through Any desk or team Viewer ?
Ots easy just install driver
can someone fix my openport too?
R1 56kOm, r2 10kOm, r3 100kOm
4.95v.
it's safe for upgrade maps?
But original to support the company But my clone is flawless on my 01 wrx, have wrote maps at east 50 times.
Dont connect to internet during flashing, then its safe.
Wanna fix mine?😂 I’ll pay.
Have you EU version to sell?
I don't sell these. I just repaired it. From the comments from other users who know more about these things than I do , I wouldn't buy this fake one.
You can also run a jumper from pin 11 to 7 i believe. Email me for pictures. Mine was also dead.
Have you figured out a way to prevent these from getting zapped when openport driver connects to the internet and receives the kill command?
Andrew Lee I haven’t done anything further with this as it wasn’t mine and my boss has done all the tuning he needed to do. Didn’t know about the kill command. Clever stuff!
Any success in unbricking?
I would think it's something in the later versions of ecuflash that would brick these fakes, just to play it safe I'll start with earlier versions of ecuflash.
@@crazyDIYguy Thanks mate have you tried other versions / if yes which ones so far works ?
Hey @andrewlee88 you mind sending those pictures over?! Tyia.
I fixed mine by buying a U.S. made original. Why buy a Chinese knockoff when the U.S. original is so inexpensive?
I didn't buy this, I was repairing it for someone else, but when he bought it from Amazon he believed that it was genuine and it had the price to match....
Because chinese clone is readily available including shipment. Unfortunately, to order original tactrix from US is cumbersome complicated process, with long waiting time.
Theyre only a 2 person company support them and buy a real one
Why are you even supporting the Counterfeit market. You sure spend alot of time fixing a problem from a Fake product that is popularly used on consumer products Rranging from 5 -50k USD. I hope you understand by supporting these counterfeiters you are supporting stealing money from families of Small american business owners. I do appreciate your knowledge of repair though.
the original tatrix had same problem to so its just a design problem china ones just got cold solder joints vs the original with good solder joints also usb port is weaker then the original to lol
