Need a stereo microscope...I am going to try shorting where pin# 20 pad should be connected to, and see if I can boot it. If not I have ~30 of these and will sell them on eBay. I think the ME9.6 will be easier to work with.

Back from the dead!!! I can now read and write to the ME7.6 aka Cadillac Catera ecu's. The file size is 512kb. and reads as: 44/1/ME7.6/6/26_0//7606296e/02960501/020603/. It is a bastard child of a ecu/ecm pinout of an Alfa 7.3.1, the maps look like a ME3.1, and can only be read as an Opel / ME7 Huh


I tried to use the EEPROM tools:

ME7EEPROM.exe - No communication micro (OBD & Boot also tried all CSpins)
me7_95040.exe - No communication micro (OBD & Boot also tried all CSpins)
eepromtool_04.exe - It said not ME7

I would be happier if I could immo off these. I think OLS recognizes ~40 maps

I'm going to try more cables Wink
