K, got my ECU from jason (Emance)
Im running a Redtop SR in an s14. Stock SR with T28, 550 topfeed RC injectors, stock MAFS, z32 fuel filter, walboro 255.
At full boost it seems to hit the 12.5 area but then wanders to 15.5 and sometimes even 16.5 (fluttering).
I'm using an innovate wideband (very accurate) that was previously used on my old setup which was super duper rich.
Thoughts and opinions? Why is it so lean?
is the problem fuel delivery?
