While it is clear that a responsible tuner has a duty of care not to carry out procedures on a vehicle that is
obviously in an unfit state for tuning, it is reasonable to expect that the owner of the vehicle has a reciprocal
responsibility to not knowingly submit a vehicle for remapping with latent defects that could be exacerbated
or cause further damage. As such, it is normal practice to sign a damage waiver before a vehicle’s output is
measured on a rolling road dynamometer. If the owner is uncertain of their vehicle’s state of repair, they
should ensure that the tuner is qualified to carry out an inspection or assessment and, if necessary
systematic fault-finding, diagnosis and remedial work. This is made much easier by the ready availability of
on-board diagnostic interfaces, a diagnostic scan plus check on the vehicle’s maintenance history should be the starting points
for any pre-tuning assessment.
