What's up guys, installed a new Hondata Canflex this past week and uploaded a tune from my tuner and am getting a P2122 that I cannot get to go away.

Any help or ideas would be appreciated

Steps of fixes
-After initial install I realized i was on an older version on hondata that didn't have the beta update
-Updated and re-flashed
-Triple checked all pins/connections, unplugged and resat anything near where i worked.
-went over all pins etc on the actual pedal, no wires taught etc
-Re-flashed to my pre-canflex tune, still same code
-Back on canflex tune now, Im lost

The only thing i can think of i haven't tried yet is unhooking the canflex jumper to see if the impedance is in that wiring, but waiting on confirmation i can start the car on this tune with that unhooked with no issues.
