Sr20 haltech timing question

I have a question if anyone knows. Do I need to unplug tps to set timing if you have haltech as standalone? The reason I ask is because it’s hardwired into harness

Setting timing is completely different from the factory ECU. The reason you have to unplug said TPS sensor is to put it into diagnostic mode.

No, there should be a locked timing mode/setting on the ecu.
