Hey guys, I have a question. Been wanting to play around with some maps on my 99.5 so I got a William programmer. I put each chip in the programmer and read each chip seperately. Once I had the two files, I used VAG EDC suite to merge the files. I did the LLL file first and HHH file but it wouldn't find the maps so then I did the HHH file first and it worked perfect.I was able to find the bad hot start map and fix it. I also did EGR delete, and massaged the torque map a bit as well. Then I did checksum with a free MSA15 checksum program I found on the net. So then I split the file into two files and wrote each file to a new AM029F010 chips I got off ebay. I didn't know which was the HHH and LLL file so I tried it both ways and neither would allow the ECU to boot.
Any thoughts what I screwed up? How do I know which is the HHH and LLL chips? VAG edcsuit just lists it as file 1 and file2.
