First Post Tuning Help
 

I tried to make a post in the ECU section but didn't go through, so guess I gotta make a post here first?

​​​​​​1990 miata someone else's project
94 1.8 built
90 tranny
Gt28rs
550cc rc injectors
Innovate o2, idk which one though

It was definitely "tuned" before and runs on the current map. Base map for a 94 doesn't run at all though. Ms1 shows afr table in volts. Changing to any innovate wideband makes the car not run in tunerstudio. For some reason narrowband it runs fine. That was the gist of it. I'm not sure, is this a real obvious and dumb question? It's why I made an account. Everyone I know uses ms2 and isn't familiar with the issue.
