Let me know the price please.....depending i could be interested 
Hi mate, I've had quite a few PM's from other users wanting to know more so I have asked Mike about group rates
Some more pleasing info!!
Covers almost all Opel cars, even new cars
With CAN- BUS based diagnostic, such as Vectra-C, Astra-H, Zafira-B.
The unit will report the fault state and feedback of the activated output. This will helps you to find the failed components more easily.
With "My Naff Code Reader", you can map keys to the immobiliser, and remote keys to the central door locking, you can also reset, and program the following immobiliser related items: ECM, BCM, IPC (you will need the vehicle security code, which can be found on the CAR-PASS)
You can also reset, and program the Service interval reminder on Astra-G, Zafira, Corsa-C, Meriva
You can code SAB6, and SAB8 airbags with the software.
The diagnostic interface is USB port based, so there will be NO COMPATIBILITY ISSUES, with serial to USB converters.
The program lets you to read out and clear fault codes, shows you live data, lets you to perform output test, and supports remote, and key programming.
Since Opel uses many pin in the OBD connector, the diagnostic interface works as a multiplexer, and selects the appropriate pin for communication.
PIN3, PIN7, PIN8, PIN12 = Serial Link (ISO9141, KW81, KW82, KWP2000)
Fault codes will be shown with all available information:
Full fault code text description
Full status information (Present, Not present, Intermittent)
You can print out, save, or copy the fault codes to any other application.
From the fault codes window, you can go directly to the measuring blocks window.
The program shows you measuring block information on many control module, you can choose anything from the list on your own. The program is capable of showing 8 measuring block parameter simultaneously. The sample rate is depends mostly on the communication protocol. For example, older system, like Omega-B X 25 DT Engine (ISO-9141-2) can be very slow, during communication, while newer Multec, or Bosch units are faster (using KWP-2000) , and the newest CAN based control units are very fast!
You can also run output tests on many controllers.
PIN6-PIN14
PIN3-PIN11
PIN1
HSCAN-Dual-wire, High Speed CAN- BUS, 500 kbps
MSCAN-Dual-wire, Medium Speed CAN- BUS, 95 kbps
SWCAN-Single-wire, Low Speed CAN- BUS, 33. 3 kbps
Current price is £200, will see if I can get it down....
