Windows software supports custom programming and data analysis, while extended data logging and diagnostics help monitor engine operation.
Data flash memory stores up to 60 minutes of operating data at 10 samples per second. User input functions include a two-stage RPM limiter, nitrous retard and shift kill. User output functions include shift-light control, nitrous activation and electric-shifter control. This kit is identified by vendor Daytona Twin Tech and part number 17821.
