Locking Ignition Timing with Connector

In my understanding that is normal.
Grounding the TEN connector blocks the effect some engine sensors have on timing so you are left with the uncorrected timing map.
(Narrow band corrections, temperature sensors, knock sensors etc are ignored.)
This map will still change with rpm so usually idle is set with screw on TB to 850 when checking timing.
