The project wasn't to reverse engineer other peoples work bit to write our own implementation using the applicable ISO documentation for guidance, everything I need to know is in these pages, albeit at a hefty cost of 500USD but, IMHO money well spent for what I would hope would have been an exceptional product.

whats it called???

have you got a link?

can you explain this layer buisness, how do they implement it, data rate?

No, these are what can be described as 'layers' of abstraction to the physical hardware interface from the software. Some protocols have a single layer some 2 some 3 or more, with the lowest layer being closest to the physical hardware and the highest layer being closest to the software that controls it.

so they are re inventing the wheel!

dumbass!

facts are, as yet it cannot be done other than what is already released!

as for reverse engineering, if people can code it then there is someone who can de code it!!

its been done many times on software thats more complicated than stuff that will run on a '98 o/s.

in fact this computer is running an o/s thats only a couple of months old and is made by a company more profitable than whoever makes nanocom.

(john, i havnt forgot, still testing)

it took me seconds to circumvent any protection it may be using.

its been achieved by a group effort, as such it is of benefit to many!

stop bigging up a device that doesnt work and its costly. we are trying to achieve a solution that will benefit us all without having to shell out hundreds just to find out that the cars ferked and spend yet more hundreds.

as for dealers and specialists, who cares if they don't make money. i have the right to repair my own vehicle. they wont get my custom anyway and i have no interest in bieng a mechanic for a livin. it would spoil the fun.

i might aswell plug a cucumber into the dlc as plug a nanocom in!!

If you mean the normal OBD codes, your right. All there in the iso norms. But it is the extra code manufactures use for diagnoses and programming, that is not published. Companies like Blackbox or nanocom have to reverse engineer those codes sent and received from the different ecu's. Take for example the Body Control Unit from a Disco II, Landrover did not publish any code for it. For decoding it you will need a testbook and the ecu and register all the write and read sequences.

Cucumbers ar suposed to be in your salad:mooning:

Thanks for the tip Gav, you do realise that I will be in trouble with the missus now for spending so much time on the computer reaserching T4 and not painting the lounge.:behindsofa:
