Timing curve mystery
Ahhh...so you told the box to not use the built in advance curve and it’s still advancing.
To me, that means either you didn’t actually get it turned off or the box has an issue that is still making the timing advance.
IDK but if I were you I’d seriously think about leaving the distributor locked out and I’d use that box to make the timing curve I wanted digitally. The instructions sound pretty simple too.
I’m not sure yet if you can do a 3D curve without boost or nitrous but if you can you could hook up and map sensor and build a really nice curve.
