Daytona Twin Tech 17811 M8FI Gen 9 EFI Controller

Daytona Twin Tec M8FI Gen 9 Auto Tune fuel injection controller is fully programmable plug in replacement featuring a billet aluminum housing with a black anodized finish.

The Daytona Twin Tech 17811 M8FI Gen 9 EFI Controller quickly auto-tunes fuel curves for front and rear cylinders on a dyno or on the road. Its alpha-N fuel control is designed to address tuning challenges associated with long-duration, high-overlap camshafts.

Windows software provides custom programming and data analysis, while extended data logging and diagnostics support tuning evaluation. The controller’s 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, nitrous activation and electric shifter control. This kit does not work on models with variable valve timing. Some aftermarket exhaust systems may require modification or relocation of their O2 sensor port bungs to avoid clearance issues.

The Daytona Twin Tech 17811 is listed for select 2018–2020 Harley-Davidson models, including the FXBRS, FLHCS, FLDE, FLSL, FLSB, FXLR, FXFB, FLFBS and FLFB.
