Hey I Would like to keep my stock primary O2 sensor and as I understand the secondary sensor is narrowband anyways, so I would like to replace that with a wideband and have an additional pinout in the ecu that could read those readings for tuning reasons. But I am completely lost as to how to do this, tuning with flashpro btw

Pulled right from the Hondata Flashpro help file for the TSX. This only works if you have the 07-08 ECU conversion (or an 07-08 TSX) and Hondata Flashpro.

TSX 2007-2008 ECU
