Honda FN2 K20Z4 cam trigger issue

Do you mean you have a trigger issue or VVT cam position issue?

In the log the trigger looks ok, but the VVT hasn't been calibrated.  To calibrate the tooth offsets you need to hold the engine at fast idle above the RPM lockout and set the cam angle test to calibrate, it will turn itself back to off after a few seconds if successful. 

It looks like possibly the VTEC or VVT is bouncing on and off so unplug those solenoids for now, your GP output 1 & 3 setups dont look right so that will be the easiest way to eliminate those interfering.  

Change your injection mode to sequential and change the E-throttle frequency to 1000Hz.  

If you have a trigger error rather than a VVT error then please do a trigger scope and attach here.
