Visit Preferences to set your user name Summary of change: ||MembersPage/Sascha/UrsfourANNpnp||MembersPage/Sascha|| After plugging in the ECU the first time (with INJ and coils unplugged), I uploaded using the Audi Tool under Tools > Firmware). I noticed that everything was working correctly except for the MAP sensor, which upon ECU startup (ignition) would start to count up (kpa) until approx 328. http://www.vems.hu/files/MembersPage/Sascha/Audi_ANN/vems-ann-map-counting-max.jpg After quickly speaking with Marcell, he suggested to check the MAP and see if the resistor is not set properly and that it could be removed and bridged (0 ohm) as it's not really needed. first pass with the soldering iron I went over every solder point on the back side and connection to main PCB, no change. http://www.vems.hu/files/MembersPage/Sascha/Audi_ANN/MAP-resoldered-all-points.jpg I then proceeded to remove the resistor and connected solder pads on MAP with solder instead, issue also still remained. http://www.vems.hu/files/MembersPage/Sascha/Audi_ANN/MAP-resistor-removed.jpg I then took measurements at PCB connectors with DVM while ECU was connected to the car. Between pins 3 (5v) and 2 (GND) = 4.93V Between pins 2 (GND) and 1 (V out) = it was also a falling voltage from when ECU is turned on around approx 1.x V settling to ~0.38 V.
