Hi,
I have GQ-4X. I can read eproms from instrument clusters but not write with this device. Chips are on the list. Tried and failled with 93x66, L56 (93c56).
Does anyone have any tips? Could this be because some chips have different pinout or packaging, like reversed, rotated, PDIP, TSSOP?
I thought this unit is automatic?

I tried with 0 speed, no change
I put same SOIC8 clip in to digimaster II and it was reading and writing no problem.
It's not a contact or speed.

Are you doing in circuit read/write with GQ-4X? OR you have desoldered the chip off the board?
