    Default GDScan question

    Can GDScan be used to log wide band data? If so how is the WB O2 wired in? Through the AC Pressure wiring?

    You mean garydoug's scan 9495? if there is a way, i do not know it. I didnt think you were able to with scan9495.

    with datamaster you can thru the ac pressure sensor wiring, but not with any of the other programs to my knowledge.

    You can log into the ac pressure pin (D12 red/black wire) on the PCM however the data will show it as pressure and you would have to convert to the wideband reading somehow. I may be able to help with that conversion

    Another long term option is to use the "D27" feature in the app Settings that logs the unused pin D27 voltage to the table as 0-5 vdc. Wire your wideband to pin D27 and select that option. It replaces the Baro pressure cell in the table (a static value that is not used for much anyway). The displayed reading is in the range of 0-5 vdc. You will have to interpret that somehow to your sensor.
    The downside to this is that you would have to install another wire and terminal to pin D27 since it is likely unused for anything and has no wire.

    the output on my aem is 0-5vdc. thank you for this. resolves alot of issues with tuners no longer having datamaster (tts stopped supporting it) and i love your program.
