No Wideband input into ecu

Post by astute80 »

Hi, I connected my PLX o2 wideband into B29 of the ecu and selected EGRL in the wideband lambda input. However, there is no reading in hondata sensor or datalog.

Was there a wire in that spot of the harness?

No, it was unused so I connected the wire there

The Japanese ECU may not have the circuitry needed for this to work on that input since there was no wire there.

This information was from Hondata that B29 is supposed to be unused

I do not think that ECU has the internal circuitry to support an input on B29.
