Hello, my colleagues. I am encountering a big problem here. I am trying to modify a vw passat 1.9 tdi 90 hp from 1998 with MSA 15. I've read the 2 eproms 27c1001 with the minipro tl866cs programmer. I have bought 29f010b eeproms. I followed the instructions (Tunning guide for msa 15), i did its checksum with winols 1.721, but the car won't start. if i write the original soft into the 29f1010b eeproms the car starts. if i modifiy it won't start. what would be the solution? please help me, i am in major need of help.

Here is files. Ori and Tun...

Do you use sockets or solder chips to board? I can't see your files, send them to spire44@o2.pl

Yes using sockets. I solved the problem. The car starts and goes very well. You can close this topic. Thank you very much for your help.

You can write the solution for other members. It is not nice to ask for help when in trouble but do not share the solution when you have it.

This solution is : You should pay attention when you save the files in your computer...It was amistake instead of HHH it was LLL..
