What we calibrate

Among other things, we adjust the maps for injection, ignition, VANOS, boost control and torque monitoring. Torque monitoring is raised and adapted to your setup, not simply disabled. Power, torque and boost are tailored to your wishes; the achievable maximum depends heavily on the installed hardware. Ask us via the contact form for a rough estimate in advance.

Durability and consistent power delivery are our top priority, and we are happy to discuss your project beforehand.

How it works

1. We create a base map from your vehicle information and send it to you by e-mail, together with any notes for flashing.
2. Log each version twice in 3rd gear and twice in 4th gear, from 2,500 rpm to just before the rev limiter.
3. Send us the logs by e-mail – we then create a revised version.
4. This repeats until the tune is finalised and you are satisfied.

Frequently asked questions

Which fuel should I use?
