Most people are surprised how quick it is. For the majority of cars a remap is a same-visit job measured in hours, not days — but the exact time depends on how your ECU is read and what checks are done first. Here's what to expect.
For a typical road car, allow around 1 to 2 hours from arrival to driving away. That covers the diagnostic check, reading and backing up your original file, writing the new calibration, and a quick verification afterwards.
We never rush the parts that matter — the health check and the backup come first every time, because they're what keep the job safe.
Most modern cars can be flashed through the OBD port, which is the quick route. Some ECUs are locked or need to be read on the bench, which means removing the unit — that adds time. Your vehicle's make and ECU type decide which applies.
If the initial diagnostic turns up a fault, we'd resolve or flag that before tuning rather than mapping over a problem, which can extend the appointment.
A mobile appointment at your home or work takes about the same hands-on time; you just don't have to travel. We bring everything needed to read, back up and write the file on site.
Yes, many customers do. For a straightforward OBD flash you can usually wait with the car.
No. The vast majority of remaps are completed in a single visit.
