Here is the programmer.

Can you see anything obvious ?

Maybe you could try putting the chip back in the dash to check it still works and hasnt been corrupted.

all i can think of then is it's the serial to usb convertor your using or are you using straight serial? i used min on a convertor..

[88GreenVN]

I have been using a straght serial cable off com1

Have just installed a usb to serial on com3. Looks better but still not pulling in the correct data.

Also will not write, even tried a blank chip and changed only one bit, still would not write.

So have tried 3 computers 2 different connections types 4 differnt computer chips including blank.

The1@ what are your settings com3 SI Prog API ?

[The1]

yep that's it, should also have nothing ticked for the polarity of the control lines, im on win7 x64, im on 2.07c

[88GreenVN]

Okay, that is the same as the current system.

Dumb question maybe, device is x2444 eeprom / x2444

do you have some other program you can recommed that I can try?

[The1]

no it's only program that i know of that will work with x24c44 chip.

[88GreenVN]

what about the com port setting.

bits per second : 9600
data bits : 8
parity : none
stp bits : 1
flow control : None

yeh same here, dunno what's going on, working fine here So in the program youve got X2444 eeprom and x2444 in the two drop downs?

See images, a second question is do you need to change all 3 sections with the new hex numbers?

Also a question about the main check digit, what if the numbers add up to more the 15, you can not have a negative ? ie 999999 when you add 9+9+9 = 27 ^15 = -11 ?
