A few vehicle remapping misconceptions

Remapping is only for boy racers, there's a generic remap, you have to do every stage: the myths about remapping haven't changed in years.

We're still surprised by how often we hear the same myths about vehicle remapping, and they haven't changed in years.

Remapping is just for boy racers and supercars

It's probably the biggest misconception of all. Plenty of our customers do come to us with custom-built and high-performance cars, but almost any modern vehicle with an ECU can benefit from a remap.

  • Work vans and 4x4s get more pulling power with a load on, from van remapping and SUV and 4x4 remapping.
  • Fleet vehicles use less fuel, which saves a business serious money.
  • Cars gain speed, torque, acceleration and pulling power.
  • Turbocharged engines gain the most, but every vehicle can benefit.

So no, remapping isn't only for fast cars.

Should you ask for a generic or a custom remap?

We'll just say it: there's no such thing as a generic remap at JTK. Every remap is written for that make and model and for your vehicle's own history. If a company offers you a choice between the 2, give us a call.

Each vehicle goes on our dyno first, to check how it performs now and where it can improve. We then remap the ECU with specialist software, retest the car on the dyno and take it for a drive to make sure everything works as it should. Every car is built differently, so every remap is custom to yours.

Will my dyno figures be the same everywhere?

Most customers want to see the power figures and how they've changed, and we're happy to show you. Bear in mind that dyno testing isn't an exact science. Air density, location, height above sea level and other variables all affect the reading, so the same car can show different figures on another dyno.

That doesn't change the remap. The dyno helps our technicians find their way around the complex maps in your car, and the performance gain is there even if a different dyno reads it differently.

Do I have to go through each remapping stage?

No. It's up to you how far you go, and you can go straight to the stage you want. Stage 1 is software only, Stage 2 adds an exhaust and an intercooler to the remap, and Stage 3 brings bigger hardware changes that alter the look and feel of your car far more.

A basic ECU remap suits everyday drivers who want more power and fleet vehicles that will benefit from an economy remap. The further stages are for performance drivers, and our performance remapping page explains each one.
