Is the lamba reading in the datalogger pretty accurate?? Reason i ask is that i remember a discussion about the ignition advance reading being way off. So i wonder if the same is true for the Lambda reading.

TIA

Its going to match the lambda value in Rom editor. If you have checked that the voltage coming from the wideband into the honda ecu is correct and matches the voltage in Romeditor, then the corresponding lambda value is correct.
