R270 vs Vito EZS

[levisdj]

I just got this r270+... some days ago I managed to break some ezs...anyway I'm trying to read R1 from this Vito EZS... and not getting any data....looking over the forum I saw that it was best to solder directly to the MCU, did that too... no result... I'm attaching a picture of the connections maybe someone can point me in the right direction....

r270 have other connection,see manual

This pinout came from r270 software...can you please detail?

Same thing mate...look closer...same pinout but soldered to the mcu

[mercis]

make chip hot,have you r270 big black box?
upa can 1l02m with sec bit good read

[levisdj]

I have this one ....!

You have the better quality R270 works 100% for me :hmmmm2:

[levisdj]

Ok, so what is the problem then ??? :2in1:

[twincam]

Mine DID a couple of them in the past but now It cant read that mask either ,any other processor is reading ok so I did this with UPA .

[levisdj]

So maybe it could be just a bad tool.... but I managed to read the eeprom on the R2...Immo MCU...
