What Is Tuning & Coding?
The DME is your BMW's engine computer. Tuning reflashes it with revised maps for fuel, ignition timing, and boost — either an off-the-shelf stage tune matched to your mods or a setup dialed in for your specific hardware. Coding is the other half: activating and adjusting features the car already supports, like folding mirrors on lock, digital speed display, or removing start-up delays. Both are done in-house, not mailed off.
