Wideband Closed Loop

Watched the webinar for closed loop and wanted to ask the following which might apply as a general also question .

When we are tuning vehicles that do not have from stock a wideband O2 sensor and we use the LM-2 or something similar , once we finish the tune and install for example a afr gauge with a wideband should we connect the wires to the loom (engine loom) and also use the analog harness and send the input to the ecu ?

If you're going to have a wideband controller in the car, I'd always advise wiring it to the ECU. Even if you're not using closed loop lambda control, this will allow you to use logging in the ECU or auto tuning where applicable.

Thanks for the input .

Also in the webinar you used the Haltech CAN wideband , can we use that on also non can vehicles but connect it via can to the standalone such as Haltech or Link etcto take advantage of the benefits of such connection as explained through the webinar ?

The CAN template for the Haltech wideband isn't published, but to be honest it wasn't very difficult to decode anyway. Provided your ECU has a configurable CAN bus system, you could use any CAN wideband on any ECU. That's the great thing about CAN - It's not a proprietary system that only works with one product.
