so presumably it should be connected to 12v+ all the time, or after power on and some time after?

many leave it powered all the time along with 62 & 21, I had to install a switch on pin 3 to get mine (me7.1) into bootmode.

Thanks for your replies, and i got another question. I unsoldered 5040 and put bin with immo off, do i still need to power pin 21 with 12v+?

After so many unsuccessful tries i finally got it into boot mode:

Put 2k ohm resistor for pin 21
power on,
ground pin 24 on chip,
ignition on,
after 10 seconds release ground from chip,
try to communicate, fail,
ignition off,
10-20 seconds wait,
ground pin 24 on chip,
ignition on,
after 10 seconds release ground from chip,
try to communicate, success,
power off.

I have Infinion cpu and only that dance saved my day.
Boot mode flashing took about half minute using eobd2Flash cable
with FT232R chip and fresh drivers from http://www.fgtechnology.eu/
