Dakota Digital Speedo Recalibration Module For Harley

The SIM-1 electric speed correction module plugs into the speed sensor harness to correct the speedometer and odometer after a change in tire size, pulley size or transmission gearing. The unit plugs in directly between the stock Harley transmission sensor and the original speedometer and is easily tucked away into the bike's wiring harness after adjustment is complete.


  • With factory Harley connectors, no cutting or splicing is required
  • Two push button switches allow the original speedometer reading to be increased or decreased easily
  • Ability to correct the speed to within 1 MPH or KPH from 50% to 284% o the original reading
  • Sealed completely from water, dust, and dirt


Fitment Notes & Exceptions

  • Only works on Touring models with electronic speedometer
  • Will also fit 2007-up Harley models BUT requires hardwiring into stock harness
    • Speed correction can be made up to Harley's factory margin of error, typically 3-5% from actual speed reading
    • If correction is made beyond this, it may result in the loss of the 6th gear indicator light and cruise control

I own a 97 883 Hugger just installed an OME Speedo and tach need to recalibrate the odometer to correct mileage on my Sporty will this work to do just that?
Jesse L on Dec 14, 2016
BEST ANSWER: NOpen it only resets the speedometer to the correct speed from tire to guage.I believe I.n most states it is illegal to adjust mileage on odometer period .zyou usu a lly start at zero Nd keep the purchase documentation.
