As i wont continue work with him,i have little troubles to edit maps,read out with my BDM,read,and write back,works well,but editing soft dont work?

I manage to connect bdm 100 with cracked winols 1500 but only last week. Until now I use a older version of bdmtogo software which allow me to import in cracked ols. Last week a friend told me that if I will install last version of bdmtogo software and install the bdm drivers the winols will work with bdm 100 directly. And that is what I do and work 100%

Well it was damaged and I am here to share with you the solution.
In the electronic board you will find 2 transistors, Q1 and Q2 at the front of the board.
Q1 was damaged, replaced it and the BDM started to work again without any problems.
The transistor has the reference J7Y.
Hope this can help someone who has the BDM stopped because of this.

you can use BC547 transistor

Already posted in another thread the Atmel and Motorola MCU entire read out for people who needs to program the device.
Also inserted the update software to flash the BDM.

I have this error. Is the solution in post one the right for me.

Interface comunication error
+12Vcc power error or Communication error

And ist this the right connection for Bosch ECU and BDM 100 clone

**chli1976** · 19th December, 2010, 12:34 AM

Now i have this errror

Mpc family error x00000000
+12Vcc power error or Communication er

hi do you sendme the pw please many tanks in advance

**milkatrek** · 2nd April, 2011, 01:27 PM

Now i have this errror

Mpc family error x00000000
+12Vcc power error or Communication er

I have that same problem. I change this resistor q1 and q2.
I read eeprom maybe someone check?

**chli1976** · 3rd April, 2011, 07:50 AM

Have you try it on an other ECU

My ECU was fault, this was the mistake by me

Thanks for the useful tip. I had the "12v or communication error". Just to be sure I replaced all 3 transistors (BC547C) and the china clone BDM100 came alive again! :-).
Got 4 of he transistors for 50 euro-cents from local electronic parts store.
Thanks.
