SAFC froze now running rich...??
<-- New SC owner
The other night I was getting onto the interstate and hit a little boost, but I didnt realize it was on low boost (tuned on 22.5 psi, the low boost setting is ~16 psi.) I pushed in the clutch and it died, I looked down at the safc and it was frozen. So i turn the car off and started it back up and it now idles at 400rpm, idle surges, and dies sometimes. Runs really rich (wideband is reading under 9.6) and shakes because its so rich. From 2000+rpm it feels fine as long as your on the throttle. Safc is working perfect with my fuel map still on it.
Next day I started it and it idled fine but still rich, until it warmed up then the idle problem came back. Not sure if that has to do with open/closed loop or whatever.
Quick mod list:
550cc injectors w/walbro
Safc-II
hks vpc
hks evc5
No codes are showing.
What are some things I should look at? o2 sensor? ecu? iacv? wtf?
I realized went through a quarter tank of gas driving it 20 miles home
Thanks in advance, any help is GREATLY appreciated

First thing that pops to my mind is running at 22.5 psi, thats pretty deep. Idling at 400?...could be ignition wires, ignition system, etc. You battery may just need a little time to recover.

check that you have not burn't a spark plug.
why are you running a HKS VPC, APEXI SAFC II together???
The SAFC II modifying the signal aswell as the HKS VPC changing the signal again, while in the mean time the ecu is just blown up going WTF!!! like to women deciding each others going out clothes.
you are asking for trouble.
As you just found out.
remove the HKS VPC and go from there.
Eliminate one thing at the time.
