Bil'Solution is a mobile car-tuning garage based in Maubeuge, France, working at your home or workplace throughout Northern France, Wallonia and Brussels. Stage 1/2 remapping, E85 ethanol conversion by ECU remap (not an aftermarket box), and AdBlue/DPF/EGR optimisation — same professional equipment as a fixed workshop, fast response.
Custom ECU map for your exact engine — real, honest power and torque gains, never generic figures.
We remap the original ECU so it natively handles E85 — no aftermarket flex-fuel box, no Lambda-sensor issues.
Diagnosis first: we only optimise what genuinely needs it, to clear faults and immobilisations linked to the SCR/DPF/EGR system.

Yes. Wallonia (Mons, Charleroi, Tournai, La Louvière) and Brussels are part of our regular coverage from our base in Maubeuge, France, alongside Lille, Valenciennes, Cambrai and Douai.
No, on purpose. We remap the car's original ECU file directly instead of adding a generic aftermarket box — it's more precise, more reliable long-term, and avoids the legal-approval issues a non-certified box can cause.
Yes, our maps are built to stay within manufacturer safety limits and remain discreet.
Yes, no obligation, and we usually reply within an hour on WhatsApp or by phone.
Yes, for 6 months: if a genuine issue is proven to come from the map itself, we restore your original factory file free of charge. Pre-existing faults and normal mechanical wear are not covered — full terms on our (French) CGV page.
