Hi Guys,
I'll preface my question with letting every know I'm based in Dubai so using ultimate conversions or someone else in Australia to modify the eeprom on a headunit swap is an extremely expensive proposition as couriering a headunit back and forth from Dubai to oz would make the conversion a waste of time and money.
I have a GQ-4X eeprom programmer, and sourced a L3-L4 Headunit with Sat Nav locally. Have read all the posts I could find over the past months, and approached this as a learning process. Am using hex editor xvi32 which reads all the other bin/hex files fine so i can rule out its a hex editor issue.
The chip in the L3-L4 Head unit is a 24C16WP - but the GQ-4X only has 24C16, or other similar chips (ATC24C16, CSI24C16 etc) - all of them read the same as the files below. I'm using a 3M test clip on the board, and have continuity tested the clip to make sure pin 1 is aligned correctly for the reader.
I have successfully read the eeprom of the headunit but it looks nothing like the bin files ive seen from other users. Am wondering whether i have a lemon headunit (ie. dead/corrupted eeprom) or am doing something wrong with the reads.
I'm not after anyone to hold my hand on the file editing but would greatly appreciate a bit of advice on whether i am having a "dumbass" moment on the reads/programmer would be greatly appreciated.
I'm about to resort to plugging the unit into the car and seeing if it fires up (and gives me security mismatch error) but before i tear the car down thought i would run it past you guys.
Incidentally the car i have is a Lumina CR8 which is essentially a HSV E1 that was exported to the Middle East with SS headunit/clusters but with HSV seating/steering wheel etc. Am happy to provide the reads to the forum for both the original and new head unit once I've figured out what i'm doing wrong.
appreciate any help.
