How to set up ActiSafety ASH-1 Head-Up Display

If you just like me have bought a ActiSafety ASH-1 Head-Up Display from China, and you don't read Chinese, then you might have a problem just like I did. When I got my HUD and installed it in my Porsche Boxster, I soon found out that the HUD read the speed wrong and had to be calibrated. But how? The instruction manual was in friggin Chinese!

My solution was to find the manufacturers Chinese webpage. I ran it through Google translator to see if there was a manual in English, but there was none to be found. But I found the Chinese manual, and by copying the text in the manual, running it through Google translator and finally doing a little tidying up, the instructions to set up the HUD became understandable. Here is what the instructions say:

To enter setup mode:

(1) Switch off HUD power, when it is turned off, press and hold -> key while turning on power to enter the setup state.
(2) The screen display value corresponds to the list:

Screen display value - The corresponding vehicle parameters
1 - Speed sensor signal (options 1 - 16)
2 - Speed correction factor (options 100 - 80)
3 - Tire width
4 - Tires profile
5 - Tire wheel rim size
(Note: tire specifications for the 195/50 R15: tire width / profile and R rim size)

(3) Selection keys <- ->, select the corresponding model parameters.
(4) Use M Button to confirm the storage parameters, and exit.
(5) After setting all the parameters, the HUD can be restarted HUD normally.

Set up instructions:
A. Set the tire specifications (can be found on the tire), and store and exit.
B. Drive the car for some distance, observe the HUD values and the speedometer readings. Set the sensor signal, possible settings 2, 4, 6, 8, ....
The HUD theoretical value should be faster than the speedometer reading by 5-10KMH.
C. Fine-tune the speed reading of the HUD. Factory preset to 91, can be adjusted according to the error size.
