Is a remap worthwhile on a working van?
Yes, mainly for low-end torque: it makes pulling away loaded easier and avoids working the engine hard at every junction.
What makes Toyota's electronics different?
They use Denso ECUs with their own reference system, quite unlike the Bosch or Siemens units standard in Europe.
Does it affect reliability?
A well-judged map respects the thermal and pressure margins of the engine. On working vehicles we apply more conservative criteria.
