Any third party device can not tell the ecu to be in closed loop or open loop! Impossible with the Honda ECU. The Honda ecu will self learn unless its programmed physically out of the ecu or fully replaced, don’t believe everything you read ! I know how all OBD1 and 2 and OBD3 ecu’s work like the back of my hand.

OBD2 is no pain in the arse you just by the obd2 conversion ECU plug it straight in simple plug and play, just cots 800$ extra. Plug and play is no pain in the arse!, if it is hmmm I guess sex is also a pain in the arse also !! LOL all you do is push and its done.
