DME Tuning, Repair & Performance Collision Repair in Carrollton, TX
A DME — Digital Motor Electronics — is the engine control module at the heart of BMW, Porsche, Mercedes-AMG and other performance brands. Westway Collision Center handles both sides of that world: emissions-compliant performance tuning and expert DME repair, alongside factory-standard collision restoration for high-end, luxury, and exotic vehicles — based in Carrollton and serving Dallas and the DFW Metroplex.
What is DME tuning and what does it do?
DME tuning recalibrates your engine control module — fueling, boost, ignition timing, and throttle maps — to unlock the performance the factory left on the table.
The results you feel immediately: sharper throttle response, stronger mid-range torque, and smoother, more eager drivability — not just a peak horsepower number. Every tune we deliver is street-legal and emissions-compliant. Typical gains vary by platform, and we walk you through expected results for your exact vehicle before any work begins.
Do you repair or replace a failed DME/ECU?
Yes — we diagnose, repair, and clone DME/ECU units, which is often far cheaper than a new module from the dealer.
Common symptoms of a failing DME include no-start conditions, limp mode, persistent check engine lights, misfire codes that ignore new coils and plugs, and modules that stop communicating with scan tools entirely. Our process starts with proper electrical diagnostics — not parts darts. When a module is genuinely failed, we repair at board level or clone your data onto a replacement unit and code it to your vehicle, preserving immobilizer and adaptation data.
Which cars do you tune and repair?
We specialize in BMW / BMW M, Porsche, Mercedes-AMG, Audi RS, McLaren, Lamborghini, Ferrari, Bentley, and Aston Martin.
These platforms share one trait: sophisticated engine management that rewards expertise and punishes guesswork. Our technicians work with factory-level diagnostic equipment and brand-specific procedures, whether we are tuning an S58, repairing a Bosch DME from a 911, or calibrating an AMG after collision repair. If your performance marque is not listed, call (214) 888-2886 — if we cannot serve it properly, we will tell you who can.
Will tuning void my warranty or affect inspection?
Honest answer: tuning can affect powertrain warranty coverage, and we explain the implications for your specific vehicle before any work — and yes, we only deliver emissions-compliant, street-legal tunes that pass Texas inspection.
Magnuson-Moss protects you from blanket warranty denial, but a manufacturer can decline a powertrain claim linked to a modification. We lay out exactly what that means for your car, your coverage, and your risk tolerance first. Every tune we sell keeps all factory emissions systems fully functional — we do not offer, and will not discuss, anything else. Vehicles leave our shop able to pass Texas state inspection as delivered.
Can you repair collision damage on high-end and exotic cars?
Yes — collision repair for luxury and exotic vehicles is our foundation: OEM repair procedures, a computerized frame machine, and ADAS recalibration under one roof.
Exotic structures — bonded aluminum, surface fiber tubs, mixed-material chassis — demand the manufacturer's own repair method, not a generalist's habit. We follow OEM procedures, verify structure with printed laser measurements, match finishes with Sherwin-Williams spectrophotometer readings, and recalibrate every driver-assistance system before delivery. Documented, factory-standard repairs are also what preserve your vehicle's resale and collector value.
Why choose Westway for performance and luxury vehicles?
Because one facility handles both sides of your car: certified collision restoration to factory standard, and performance DME work by specialists who understand these platforms.
An I-CAR Gold Class collision team, a computerized frame machine, a time-efficient paint booth, and DME diagnostics under one roof means no handoffs between strangers. Every repair carries a written lifetime warranty; every tune is documented with before/after verification. Your vehicle is stored indoors, insured, and treated like it is ours.
