Any DIY firmware update is invalid on our OP-COM cables. You need to purchase new Opcom 1.59 interface (Item No: SP205 only). 

But the Op-com 2010V software can be downloaded free here:

2010V op com software supports English only. If you need German version, then choose opcom 2009V


Operating system: Win XP only

How to install op-com 2010V Hardware V1.59 CAN OBD2 for Opel


Customer feedback/review:

1) Opcom V1.60 is known to be buggy for Vectra-C so better to use v1.59 anyway

2) Op-com V1.59, Vectra C tested and its working like a charm 

3) opcom v5 (1.59) hardware is the best cable. China clone V5 the one with real PIC18F458 works with 08/2010 china.

4) 150-200 Euros for an EU clone which is a disgrace (they neither made the original software, nor hardware, nor license hack, they just pick up the profit by selling for ridiculous amount somebody else's work). I would rather to spend 20 bucks worth v5 from China. It works.

Working solution for UPA ERRORS ON MOTOROLA CHIPS HC05

This post begins with UPA ERRORS ON MOTOROLA CHIPS HC05, then followed bad connection pictures, finally I find out working solution and would like to share with all of you.


UPA USA Programmer I got is from China: 


Problem details: 

Right I soldered all 9 wires for hc05b6 as shown in UPA USA manual 

and lifted vdd pin from plate. tried to read but will not read. 


so I ran voltage tests 2 pins came back as bad if I remove the 2 bad wires and rerun test they both come back as ok.


The first bad connection is pin 1 IRQ

The second bad connection is pin 6 PD3 


Is was gonna give up but I found some extra reference to these chips hidden away in upa folder 

The 2 bad connections seem to be the same that are described in the files I found. 


1 was a txt file just containing a few words: CUT PD3, IRQ, TCAP1

as 2 of these seem to be the same as my 2 bad connections. Check screens below.


it’s got me wondering maybe these chips will read ive seen someone else about with same errors on similar chip.

UPA USA Programmer-3.jpg

Here is working solution, works with clone UPA well

1. connect all wires as shown on chip pinout diagram.

2.lift PD3 and IRQ pins from board. voltage test in upa program.

it should show connected at the bottom. then read Smile


you may have to lift VDD but maybe not I had lifted it 1st time round and may not have reconnected properly Smile

I did not lift tcap1 or other pins that have been suggested.


it seems the trick is to lift any pins from chip that give bad voltage.

K-Tag KTM100 FWV7.003 Connection error E000079 (Fixed)

KTAG K-TAG KTM100 V2.13 firmware V7.003 ECU Programming Tool Master Version connection error (E000079) solution is provided below. 



After well installed the Ktag KTM100 V2.13 software on Win XP laptop and tried to select ECU to read and write. The software displays no ECU options under “Option” tab (all options are in gray). Meanwhile, the KTM100 software reported an error:


Interface connected…

Firmware Version: v7.3 build:0000

Error 【E000079】Customer Code Invalid”


Possible reason & Solution: engineer has worked out the solution and verified working by our customer. 


Possible causes:

1.Internet connection have not been disabled

2.Ktag driver is not well installed 

3.There is no power supply fed to the Ktag ecu programmer 

4.TF card and Shrapnel has poor connection 



1.Please disable internet/network connection before installing software. THIS IS VERY IMPORTANT!!!

2. Make sure Ktag KTM100 driver is well installed. 

Open My Computer>>Manager>>Device Manager>>Universal Serial Bus controllers>>DimSport-New Trasdata Device to check the good communication between K-tag and computer. 


Software driver installation video to refer:


3.Make sure there is a power supply fed to the Ktag ECU tuning kit. 

4.If all the previous conditions are no problem, then the problem lies on the TF card. Make the shrapnel firmly attached to the TF card. 


In our customer’s case, the TF card is loose connection. He higher the shrapnel to make it firmly attached to the TF card, then the problem was solved.
