upa read in circuit?

[Nicolas9]

HI guys.

i want to read a micro eeprom 93c66 from a bike with UPA, in circuit. but it fails me, even when I select 3.3v. I can read succesfull with x-tool on 3.0v, but i dont have x-tool around every time. and i have many dashes, want to save time by reading in circuit (with upa).

- i dont see a crystal which I bridge. is there some other trick i can use to use my Upa to read this eeprom in circuit? (see photo)

- can I change the hardware of my upa, so it reads with 3volt all the time? (i dont need 5v or other options for this upa)

thnx a lot guys!

I have this latest UPA this more modern that it is not necessary to change jumper in hardware, change only in the program 3.3v for 93CXX and 2.7v for 24CXX. I make the readings without problems.
For the eeprons 93CXX pins 5 and 7 have to be welded together, 6 and 8 also have to be welded together.
I was reading a Toyota Etios with 93C56 in the circuit and it was not possible because pin 7 of eeprom is not next to 5.
I can do the reading in the circuit of Etios only with old Tacho Pro.
