Help with ME7.8.1 needed

[GUEST911]

Hi!

ME7.8.1 does not want to communicate with MPPS. I tried via OBD like the previous similar car I did a while ago (with success), does not read the ECU info completely and does not read nor write the tune. In boot mode (Generic Bosch ME7.8.x / 1Mb ) does no want to communicate at all. Neither with ST10F275 K-line etc selected, but just throws a window with text "Put Micro pin P0.4 to ground and P0.5 to +5v or +3.3v using a 300 ohm resistor then power ON"

Any info available of those pins (or complete ST10F275 datasheet available)?

Could it be possible that the ECU is locked by previous tuner? No idea when or where it's tuned, but it has a tune with some problems and there's signs of soldering on ST10F275's adjacent chip's pins. In this pic https://wiki.obdtuning.de/images/thumb/a/a5/ME78_Platine.jpg/573px-ME78_Platine.jpg ( https://wiki.obdtuning.de/index.php?title=Datei:ME78_Platine.jpg ) is the chip that soldering is done, actually if the boot pin is #2, soldering is done to pin #4, but 3 & 5 are also touched.

I do not understand you, you write that you have ST10F275
in the pictures you show ecu from am29f800

Well, the processor is different, but flash chip is the same, that pic is more or less for illustration purposes only (To describe which pins were messed on that flash chip), not from actual ECU.
