Evening guys. I am new to this but have been doing quite a bit of reading. I have a stage 1 map file i am trying to flash to my ecu m3.83 06A906018CG with a stage 1 file software version 352127. I have mpps 13.02 and the 3.83 to 5.92 adapter cable but from my understanding i need to bridge pins 13 and 16 on the obd male connector to get a 12v to pin 43 on the ecu so i can write to it. I thought it would do it automatically with the adapter cable to flash via OBD but i get message saying ECU Programming Voltage Missing. Ive searched everywhere for a way to do this and am looking for some guidance. Back in the day when i had MR2s i used to bridge pins using a paperclip is this possible in this case? Whats the method to get them bridged? Car is a mk2 golf with AGU conversion btw

Kind regards Will

Pins on male obd: 16--+12V, 4 or 5 -- ground(-12V), 7--K-line(Write data). Pins on ecu please read documentation. You have to connect +12V, ground, k-line on ecu and mpps, only three wires and apply voltage 13V from an external power source to +12V and ground. OBD pin 16 must be connected to pin 13, in mpps choose 1.8T Bosch M5.92 K-Line, this ecu is write only, you must search ori file.

I think it is not possible to remap this ECU via OBDII. It is very simple to open the ECU and take the eprom to save the modified file.
