I have seen a few posts about some users of the Spartan 3 v2 Lite utilizing it for Subaru datalogging. My main questions are, what software are you using to datalog? If you’re using RomRaider, does the old 14Point7 NAW_7S plugin work? For the interface (green wire) what exactly is the interface in my scenario if I use my laptop to datalog? Thank you in advance and sorry if any of this seems elementary to most, the whole green wire and interface thing is the main part throwing me off.
Datalogging of WB-signal needs logging capabilities of analog input of Sofware of ECU or on ECU itself. So 0V to 5V has to be mapped to 10 to 20 AFR values. So you need to create a conversion formula as well. I don’t know RomRaider but if it can show logging of eg. fuel trims, map and so on you should be able to add and log WB-channel (the green wire) as well.
Do you have any idea of how serial logging would be possible, or what the green wire needs to be connected to specifically in my case?
