I'm having a problem with s300 / smanager on my built gsr hatch sc34. I set hot and cold boost cut at 20psi and it's hitting at 12psi. I have a neetronics 3bar and datalog shows exactly the same as my boost gauge.
I have my LC1 going into the ELD input and datalogging AFR, it goes right up to 12psi with good AF and just cuts out. If I partial throttle / boost it, it goes right up. I disabled launch and full throttle shift.
I'll post up my cal later on, thanks.
