Hello
l have just swapped a used ecu from donor Mercedes ml to another but when I try to start the car it will just start for 2sec then die but when I put key on ign and switch on for 15min the car starts and drive well, but when I switch off and immediately start it starts OK but when I remove keys on ign the car don't start until I wait another 15 min.
the things I changed are 1. pick up coil, 2.AAM, 3. ecu and 4.key
Am I missing something?

it sounds like a security IMMO problem
10-15 minute wait, makes car go in emergency mode....
