Daytona Twin Tec M8FI Gen 8 ECM For Harley Softail

The Daytona Twin Tec M8FI Gen 8 Fuel Tuner is the ultimate tuner for your Touring Harley. Piggy back tuners may be "good enough" for a mild or stock engine, but they simply can't keep up with motors producing north of 100hp. That's where the M8FI ECM comes in! The M8FI ECM utilizes Bosch wideband O2 sensors to keep your bike in an optimum state of tune!

The M8FI solves tuning problems with highly modified engines. Competitive “band-aid” products that interface to the Delphi controller still rely on speed-density fuel control. Long duration/high overlap camshafts wreak havoc with manifold pressure - especially at idle and cruise RPM. Speed-density based fuel control simply can’t cope.

Features:

  • Fully programmable plug-in replacement
  • Quickly auto-tune fuel curves for front and rear cylinders on a dyno or on-road with new WEGO IIID dual channel wide-band oxygen sensor interface
  • Robust alpha-N (throttle position and RPM based) fuel control eliminates problems with long duration/high overlap camshafts
  • Powerful Windows software for custom programming and data analysis
  • Extended data logging and diagnostics. DataFLASH memory stores full 60 minutes of operating data at 10 samples/second.
  • Powerful Windows software for custom programming and data analysis
  • Programmable user input for functions such as two stage RPM limiter, nitrous retard, and shift kill (not available in M8FI EX version)
  • Programmable user output for functions such as shift light, nitrous activation, and electric shifter (not available in M8FI EX version)
  • Billet aluminum housing with black anodized finish
  • Bosch LSU 4.2 wide-band sensors for both O2 ports
  • Easy plug-in installation

Note: All naturally aspirated motors should use the "Standard" module, 2.5 and 3.0 BAR options are for motors with forced induction only.

2.5 Bar ECM requires Manifold Pressure Sensor 17815, sold separately.
