Hello,
I tested one FG TECH as BDM prgrammer. When I read data from ecu, and write. EDC is dead.
Problem is: Programmer write data about few address line down then is starting ori file. After write is edc in diag dead.
When I use backup for BDM 100 ori from evc, unit again live.
Have anyboy thos same problem, but solved? :-)
I changed 4 74H smd parts. BDM before this repair was damaged.
Many thanks for kick right way for solved this problem.
OBD programming work good.

And I have one next idea. Pinout BDM from EVC is the same as for FG tech, but I don?t if is the same probe to bdm connect. I use originally probe from EVC No.143.
2 Daniel: When I read via evc and V54, unit live in diag. When I write via evc, unit work. When I write via V54 via ori EVC probe 143 unit no response on diag.
When I put in ori bdmtogo file to dead unit. After this step unit live again. But ori probe have in bdm pads different pinout maby.
Chinas market sold bdm probe with used first five pads in two rows. But ori have power supply and have different pinout.
But when was bad pinout I must kill MPC, or no?
Many thanks for idea.

You kill MPC if the 12v pin out is incorrect, have you tried to connect the flat cable directly to the bdm pads, like it's showed on instructions manual from Galletto! An advice, Always power the ECU 12V directly on the ECU plug to avoid killing the ecu.

To be honest i don't know if there's any difference between probes, china and original EVC, the only way is to compare.
