Hi,thanks to coelhone i try your file when i did write to 93c86 the writing process stop to 37 percent strange,but when i try with original file not modified writing ok,i think than the digit is not at good place like on tachosoft 23.1 or tachosoft have error calculation,if someone had this problem let me know,thanks.

Hi,i have elprosys diagprogIII,it's the first time than i saw that,can be this cluster have writing protection for lower down writing mileage,i go try with carprog and after that i let you know if is ok but i check your work and i see than you have swap bits because on original bin file at this address bits is swap too if i check with tachosoft,what calculator do you use,thanks.
