Does the PFC cut fuel to BOTH rotors, unlike the std ecu?

If so, it's not as dangerous as the std ecu to hit fuel CUT?

I hit it once and ***** myself, so I've turned my boost down 1 psi and thats sorted it!

Please help!

 

that may not sort it for some time. What you need to do is reduce the wastegate base duty cycle as well. Best is to reduce the wastegate duty cycle numbers and then leave the target boost numbers alone - or reduce both, but the duty cycle numbers more.

I've heard that PFC fuel cut is more safe than stock ecu, but specifics have not been authoritative. I've heard fuel cut to both rotors, and I've heard ignition cut, but neither definiteveley.

 

Also, boost control SEEMS to vary with the PFC. When it ws warm, 60 or higher, it does a great job. When the temp dropped into the low 40s and lower, I'd hit fuel cut do to the boost going over the .25 limit of the boost setting I was trying to hit. I do have an open exhaust, but creep in warm weather doesn't affect the PFC, nice stable boost, but when it gets cold, blame. Porting the wastegate might be our only option in cold weather to help it out.

Thanks guy's
But...

how much hp will i lose turning down the boost 1-1.5psi?
taking into account my mods!

First try reducing the base duty without reducing the target boost. It may be that will compensate for the colder, denser, air, and give you the same boost that you wanted.

If that's the case you will not lose any HP. Well, you were probably overboosting, and getting more HP than you bargained for, and you are going back to your target.

It the only way for you to be safe is to reduce your boost by 1.5 psi AND you are seeing a corresponding drop in resulting boost. Then you are probably loosing something in the range of 15-30 peek HP (my guess).
