Bertrange, Luxembourg — engine remapping, done properly
Your engine deserves a proper tune, not a generic setting.
OPTI-MAP has remapped Subaru and Ford Focus ST/RS ECUs since 2012. One person handles your case from the first message to the final tune — no workshop, no subcontracting.

The ECU, as it’s actually tuned — boost, fuelling and ignition maps, table by table.
Three ways to do this
No public-facing workshop: every intervention is arranged case by case.
At your home
OPTI-MAP travels to you, within a 350 km radius of Bertrange. Travel costs are calculated per kilometre and confirmed before the intervention.
By post
You remove and ship your ECU; it comes back remapped. A good fit if you’re outside the travel area.
In Bertrange
Prefer to travel yourself? That’s possible directly in Bertrange, by appointment.
Two brands, done properly
OPTI-MAP refocused on two vehicle families, to keep the time to do each job well.
Subaru
Impreza GT Turbo, WRX and STI from 2001 to 2018, Forester Turbo. Single, dual or triple map depending on the model.
Ford Focus ST / RS
Focus ST and RS MK2. SP98/E85 dual-map solution developed by OPTI-MAP on its own test car.
Behind the scenes
Tuning the ECU, then a close look at the resulting maps.


What we tell you before, not after
Any engine remap carries a risk of failure, and is not authorised for use on open roads. OPTI-MAP publishes its reliability statistics per model and answers the awkward questions in the FAQ — not just the good news.
See the work rather than hear about it
OPTI-MAP posts its interventions, dyno sheets and client exchanges on its Facebook page rather than curating testimonials.
