QUESTIONS AND ANSWERS  ·  COMMON QUESTIONS

I already have modifications. Does that affect the remap?

It often helps, but we need to know exactly what is fitted so the file is written around your car rather than a standard one.

Diagnostics and ECU

Tell us what is on the car when you enquire. It changes what we write.

Some modifications work in your favour. An induction kit or a less restrictive exhaust reduces the limits imposed by the standard parts, which gives the calibration more room. Others change the picture completely, such as an uprated turbo, larger injectors or a different intercooler, and those need the file developed around them rather than a standard map loaded on top.

What we need from you

  • Every engine, intake, exhaust and boost related part that is not factory.
  • The make and model of each part, not just the type.
  • Anything that has already been done to the ECU by someone else.

Guessing at what is fitted is how engines get hurt. If you are not sure, bring the car in and we will look.

We also supply and fit parts ourselves, so if you want hardware to go alongside the map we can fit it on the same visit and write the file around the finished specification in one go.
