Almost got to take it home today! Still figuring out a secondary O2 sensor issue.
I know on old cars that are far less complex . You could just get Dummy O2’s and use your upstream sensors for tuning ect…
Car won’t pass smog if I just delete the rear O2 through the tune. It was working before so we just need to get it working again.
That O2 sensor turned out to just be something unplugged, hahaha. Ordered a cheap Windows laptop so I can pull some logs and adjust the tune until the dyno shows up.
Sending over strategy codes over for a different tune tomorrow. Hopefully it doesn’t break this year. lol
