So after logging with the GEMU unit I just bought, the VTEC point is not changing per the lower engagment point I have instructed it to do. After searching the issue, does the wire harness need to be rewired as per this thread? https://www.s2ki.com/s2000/topic/635...nage-ultimate/

I double checked the jumpers and they are correct.

Thanks

 

So after more searching I came across a post from karcepts that says that jumper 17 needs to be open instead of 1-2 that others say it should be... Is this the fix instead of modding the vtm and vtec wired on the harness? There is so much conflicting info on this topic on this board for this topic. If someone could give a definitive answer how to get the vtec changing to work that would be great.
