Flasher Logger and Code Scanner

Unlock the full potential of your Porsche with a single, powerful tool. Designed for enthusiasts, professional tuners, and anyone who wants deeper control and insight into their engine, Rennflasher delivers seamless flashing, advanced datalogging, and complete diagnostic capabilities — all in one interface. Flashing: Our intelligent flashing protocol performs a virtual read of the factory calibration, generating a correct and verified stock file without requiring ECU bench access. Paired with our extremely stable and high-speed OBD write process, Rennflasher ensures safe, consistent, and hassle-free ECU updates every time. Datalogging: Rennflasher goes beyond traditional dataloggers. In addition to the standard OBD parameters, our system exposes exclusive custom RAM variables that we consider essential for high-level engine calibration. This gives you and your tuner deeper visibility, more precise tuning decisions, and better performance outcomes. Diagnostics: A complete tool needs complete diagnostics. Our DTC module reads not only generic “P-codes”, but also Porsche-specific manufacturer fault codes — along with detailed descriptions — to help you, your tuner, or your mechanic diagnose issues quickly and accurately.
