on his website- ive got a copy myself. so do several other people. but its uselss unless you know what you are doing. plus they had a checksum issue that was fixed by a seperate company that you would need to know details about.

its a bit of software that gives you a graphical representation of the hexidecimal and an easy way to modify it. this can be saved etc. its all in italian (easily translatable) and the company that made it no longer supports it and will not give any furthur info about it. i dont know how Astra uses it exactly. i know they remove a chip from the board and move a jumper. this must allow them to program or modify the programmimg of the chip. whether they have to "downoad" the map change it and then "upload" it or if they just change it thru a direct connection i dont know. you could use it to change any hex code actually- i used a couple of bits of flash code i have laying around to play around with it a little to understand the interface.

That's the piece of software Alex showed to me in Spa. Without downloading/uploading capability, it's useless.
I confirm they do as you said : they have to "download" the map, change it, and then "upload" it. That's what he told me anyway. He also mentionned to me the slight hardware mod they have to perform before being able to communicate with it.
Ok next step now is to find a way to download/upload stuff.
Thanks for the info,

Alright, this thread kinda died out and I'd hate to think you guys were stuck for lack of support.
I don't spell well, but I am a degreed Computer Engineer and a practicing EE (designing circuit boards for embedded applications for 10 years). I currently work for a small design services company and my lab has o-scopes, logic analyzers, high quality solder stations and other useful things. Plus, my technician coworkers would back me up if I needed to build something complicated from scratch (like a special download cable).
It sounds like the S/W you're talking about is some sort of disassembler. Any embedded software engineer would have about three such disassemblers and if the chips are COTS we could get datasheets.
Do you guys need some help with the boards/chips? If we get some spare modules out of wrecked cars we could experiment with little risk.

If you search, someone has posted pics of their ECU taken apart. So you can at least know what all the chips onboard are.
In terms of cables and such... I'm seeing two possible options here...
1. Use the OBDII/CAN interface port to connect a simple menu-driven handheld interface device. Option for device <--> PC connection for full detailed reprogamming.
2. Mod the ECU so that either the stock maps and settings (such as throttle body) can be downloaded/uploaded -or- bypass the stock maps to external EPROM where you upload/download your maps/settings. In this setting (#2) you could use an AUX port (only) for this function so that when the dealer techs reflash the ECU it wouldn't erase your uploaded maps/settings.
Personally I favor #1, but beggars can't be choosers.
This is what those who want ECU reflashers are thinking of...

... then you would just need to work your way through the program and pay off a service guy to upload it in your car -shrug-

The downloading and uploading of the software content of the PCM is not a real problem any more. Alex, who started this thread can do both and even modify the calibration (the maps). There are a few remaining issues though :
- he needs to modify the hardware in order to be able to retrieve the maps from the PCM
- nobody has an index (memory addresses) of the different parameters (scalars, functions and maps) in the calibration. Alex can only modify spark advance and O/L fuel. He hasn't got any other info to modify other parameters.
