Kpro v4 connection issue (Off line)

Post by artyperEp3 »

My Honda EP3 previously had an older version of the KPro ECU installed. Due to problems with the ECU, I borrowed a newer version, the V4 KPro, from a friend. I'm talking about a KPro ECU that had been previously installed and programmed in another vehicle. When I installed it in my car, it started. My computer recognizes the ECU as shown in the attached image, but the KPro software doesn't read it. How can I overcome this problem?

The car currently has a K24 Accord engine.

K-Pro4 45237

I've tried to show it in detail in the attached video.
