Use OPCOM to read HW and SW Nr.Original dump can find on internet.

Thank´s a lot for the usefull info. Also can u tell me how can I know wich one is mine (29f200 or 2 * 29F010 PLCC), is it with the OPCOM or there is an other way?
Thank´s and sorry for so many questions, people in this Forum are very helpfull. :thumbup:

it is not important if you will flash through OBD

I ve received already the OPCOM tomorow I will try to read my ECU with it, thk´s a lot

with OP-com you will read identification of ECU only :) op-com can't read any map or something needed for flashing. If you need information about software in your ecu, you don't need any device at all. You can simply check this SW number by your car VIN , for example there - http://www.ecu-online.com/content/7-gm-cars-pn-by-vin

Thank you, I found all info.
The only way to get this map is downloading it on internet right?
I have 2 or 3 but i´m not shure if they are the same as mine.
