First, thank you for offering help.
I had my car tuned professionally 3 years ago, and had no issues until lately. I'm not sure about the nissan 360 opto mode but I haven't changed anything except my fan temperature, RPM limit and MAP limit.
I also haven't changed any sensors etc.
The trigger counter does increment when the rev limit comes in
I did notice my voltage is very low, around 9-10v I'll have to address that.
I also have seen in my log that I've hit 14000 RPM so maybe my CAS has had it.
I'll have to check out the trigger scope and make a log of it.
It just seems to be consistent around 6700 at the moment.
