Custom ECU Tuning for M112 3.2L V6
CLK320 · E320 · C320 · SLK320 · Chrysler Crossfire

Wake up your 3.2L M112 with a precision ECU calibration tailored for stronger torque, better response, and everyday reliability. Expect sharper throttle input, stronger mid-range pull, and a more connected drive—while maintaining OEM safety strategies.
🔥 Performance Gains
- Up to +18 HP / +18 TQ (premium fuel, healthy engine)
- Factory Output: 215 @ 5,700 rpm / 232 TQ @ 3,000–4,800 rpm
The E32 features fracture-split forged steel rods and a 10.0:1 compression ratio, making it highly responsive to optimized ignition, fueling, and throttle mapping.
✔️ Why Our Tune Stands Out
- Immediate Pedal Response: Removes the dull, laggy feel.
- Factory Safeguards Retained: OEM knock and thermal protections stay active.
- Built for Longevity: Smooth torque delivery and refined drivability.
- Dealer-Safe: Discreet calibration designed for service friendliness.
🔧 How It Works
- Bench Flash Service: Mail your ECU to us. We read, calibrate, and flash it, then ship it back ready to plug in.
- Optional Induction Upgrade: Pair with a high-flow intake for even stronger mid-range (contact us).
