most will try and just get you for a pod coz most think they are all illegal, just to help all of us know that we can have them
as for ecu's only if it is noticable that it has been played with ie: extra wires that obviously shouldnt be there.
engineering wouldnt check it out either, it would just be a roadworthy tester and if they think it is not roadworthy coz of anything, the defect wont be removed until all is fixed to the standard that they want, all roadworthy testers have different ideas bout things for some reason.
engineers and roadworthy testers are usually not the same people aswell
