Ideal tuning aid for Screamin Eagle® Pro SuperTuner (SEST), Dynojet® Power Commander® (PC), and Daytona Twin Tec Twin Tuner. Twin Scan software analyzes logged data and displays front and rear cylinder air/fuel ratio (AFR) and the required volumetric efficiency (VE) correction (in percent) with the same RPM rows and throttle position sensor (TPS) columns used in fuel tables for the supported engine tuning systems.

Sold as a complete kit including the WEGO IIID dual channel wide-band exhaust gas oxygen sensor Interface for logging AFR data along with engine data.

When the WEGO IIID is connected, the Twin Scan 4 will log engine data along with the actual air/fuel ratio (AFR). Logged AFR data can be analyzed and displayed.

You can also display and print out the required volumetric efficiency (VE) correction (in percent) based on the AFR command. You can add data from an unlimited number of files that you previously saved. The data will be analyzed and incorporated into the table. Cells that vary more than ±0.5 AFR from the target value are shaded blue for rich or red for lean. You can then copy and paste the corrections into the software for the supported engine tuning systems. When used with the Twin Tuner, corrections are directly exported to the Twin Tuner file.
