When you click on the on-line calculator, a dialog box should come up with three options:
Estimated - where you input chnages based on mods
Precise - where you are making a comparision of indicated and true speeds
None - where you already know your correction factor
- Choose Precise then enter your values in the data fields on the left. Once you have entered those, hit calculate and it will generate the calibration factor and instructions. As a demonstartion, I used 100 MPH as indicated and 88 MPH as true, it gave me a total error of +13.6% and a SH calibration value of -12.0 it also generated the following instructions:
SH Calibration Value to be stored: -12.0%
SH Conversion mode Value to be stored: 0
- the ignition must be OFF
- set ALL SH switches ON
- turn ON the ignition
- press the button => memory cleared
- set ALL switches OFF EXCEPT #4
- press the button 1 time(s)
- set #5 switch ON
- set #4 switch OFF
- press the button 2 time(s)
- set #5 switch OFF => all data stored in Flash.
Notes:
1. Please make sure to follow ALL STEPS EXACTLY, otherwise the unit won't be programmed properly.
2. It is recommended to check the new value of the selected parameter on the LED before selecting and setting another parameter.
3. Should you need to abort the steps and return to the previously stored settings, turn off the ignition and then set all switches off.
4. Whenever the ignition is switched on with all sh switches down, the led should blink 2 times, meaning that there is a valid calibration value stored in memory. If you see rapid flashes for 3 secs at ignition on, the calibration memory is empty and the unit will start in Transparent mode.
5. If you wish to modify a previous set-up and change only one parameter (e.g. -8.4% => -8.5%), you don't need to issue a reset. To speed up the process, just change that one parameter only.
