Hi all
Hopefully someone can advise
Ok so my car runs fine no lights or errors
I swapped ecu for a remapped one with removed immobiliser etc
It came up with engine management light and epc light and only would idle no throttle
I swapped back and all issues went away.
The person I bought from said that my car has an issue and the remapped ecu is picking up on issue and my original one probably can’t detect.
Is this possible ?

Cheers any help would be great
