Hondata

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 ...
