Get whatever they tell you to use. If you f it up you will be sorry and wishing you used the right one. Why take chances when you can get the right one from eBaY for $1.00 or any electronics store?

If you do it with XprogM the diagram is in the software or help.

[m3m5]

Yes! i saw it but diagram isn't square it's large. Pin out it's the same?

[roth18]

Look at the number of pins in diagram and you will understand. Some pins are missing from it to save space.

[m3m5]

m8 my diagram for xprog 3k91d it's that. I told that isn't square !! Pin out it's the same????

please

[drz]

But if you count pins you will see it is square.

[m3m5]

ooohh yes !! my friend!! problem was language!! hahaha i understand your are telling me.

I have read with xprog, always when veriphy appear errors, it's normal??? i have changed bytes like tachosoft and it's ready.

dash isn't good, sometimes i connect in car and it's died! before reprogramm fails too.

you need to change resistors bocks around MCU its like 102, 201 numbers on resistors blocks. If it not help clean pins MCU desolder clean pins and solder back.
