FLASH WITH CONFIDENCE
Browse and install calibrations from trusted tuners worldwide. Pick a ready-made OTS (off-the-shelf) stage tune for V8 and V6 engines, or load a custom calibration built for your exact setup. Every flash is encrypted end to end, checksum-corrected automatically, and runs offline once downloaded — so a dropped connection never puts your ECU at risk.

HIGH-SPEED DATA LOGGING — rebuilt in 1.8
• Ready-made logging presets per engine, plus build-your-own profiles (up to 20 channels)
• Boost, intake temps, knock, AFR/lambda, timing and 70+ parameters in real time
• Auto-records your pull and saves it as a CSV tagged by VIN, date and time
• Powerful new viewer — multi-channel overlay, drag-to-read cursor, time-axis zoom and stacked view
• One-tap cloud sharing so your tuner can refine the calibration
Supported on MED17.7.5, MED17.7 V6LA and MED40AMG.
