R34 Speedo not working after manual swap

[DanMac34]

Hey all  im wondering if you can help me please I have put a rb20 box in my r34 gtt as my auto packed up and a friend had a spare box I know it’s not ideal but it will get me up and running for now.

we have done the conversation and everything is working great but my Speedo we got a s13 speed sensor but my Speedo reads double now and I bought a speed converter but still not having any luck. 
so I thought I’ll reach out and pick your brains  any help would be appreciated please as I wanna drive my car again

Ive converted a few clusters for the R33 with 320km/h dials. On the back there are some pads which can be bridged or unbridged (using solder or wick braid) to calibrate it. There is one bridge which is for MPH <> KPH; and there are combinations of bridges to offset it. There is probably a diagram 

For example; this is my conversion for a 180km/h dial to a 320km/h dial (I put custom GT-R dials on it with the GTS25t layout)

If you have J2 soldered (assuming the S clusters have a similar config to the R clusters); you may need to remove that solder
