What is the fuel cut psi on a EJ20G (93-96 WRX) ECU?
I thought I saw 17PSI somewhere, but can't find the details now.

hmmm i know theres a site that has all the PSI cut offs for those. I think the EJ20G wagon PSI cut off is at 13....

I have target boost for the '95 EJ20G (GC8 or GF8) @ around 12.7psi.
I'm looking for the boost level @ which fuel cut will happen, & I actually sort of remember reading 17psi somewhere but I'm getting old so everything is fuzzy.
13psi for fuel cut sounds a little low if the boost target is 12.7psi of boost.
Target boost for the LSS is 8.7psi & fuel cut is 12psi (except my retard car) - 130% of the target boost.
1.3 x 12.7psi = a 16.51psi estimate for fuel cut, but I'm sure someone knows this fun fact.

I've seen 17-18 psi on my stock 22T ECU with a 20G Engine Swap. It has a homemade FCD by Nick!

I have a Split Second VC2 on my car handling the fuel cut & it works well.
I have seen 19-20psi for a second before I let off with a very restrictive "t" on the pos manuel boost controller I have on the car now.
The current restrictor does not let let boost pass 14.5 psi, but it is going out & a HKS EVC is going in.
If the TDO4 can hold 15psi it will stay in & get a wild port on both housings, if not the 16G will go in after porting.
I'm still on the Ej22t ecu & it runs very-well, I just wanted to know what the factory thought was the max allowable boost (fuel cut happening after this) before I crank the boost!
