No speedo with new kpro 4

[Streetcoup]

I have an jdm eg6 with a k24a with bolt on
Running krpo v3 for last 2 year then my friend let me use is v4 for Bluetooth data
I décide to sell my v3 and bought à pnf with kprov4

Now i read my vss on kpro but it doesnt work on my speedo
Switch back to my friend v4 and all work perfect

Anyones had the same issue or can point me in à good direction

Thank

What transmission are you running and what speed signal is selected in the settings on KPro?
