Help with PowerFC boost control on GTR

Ok - I got a PowerFC & the add-on boost control on my GTR.

I have blocked off & removed the factory boost solenoid & connected the pfc solenoid between the pipe that comes off the bottom of the plenum (at the back) & the pipe that feeds the actuators. This is in line with what the manual suggests & with what I was told to do by a local workshop that has some experience with these items.

The issue is that I cannot get it to hold boost - boost is inconsistent, it spikes, is different in different gears & is slow to come on (compared to the basic bleed valve setup that I was using).

I have tried all sorts of setups with target boost & duty cycle without success...

Can anyone tell me what I may be doing wrong?

Do you know how long it takes to get the unit to learn boost as maybe I haven't let it do this for long enough?

Any help appreciated.

Brendan is getting his R tuned by Lumpy/Ken anyday now (if not already). He has the PFC with boost kit as well.

Before I bolted on the big terbs (and did a big end) I had stable boost at just under 1 bar. Couldn't get stable boost on the bigger terbs at higher boost, however. I suspect it has a fair bit to do with setting up the actuators well in the first place as Sydneykid explains in another post.

You've got HKS actuators - right?

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Yes I can see how that would put you off HFM, especially with the price of good quality brake fluid. From what I understand it as you say the BM50 is the standard BMC for a R32 GTR, I must admit I would like to go far a Genuine Nissan BM57, but lack of cash prevents that at present. With the price being so close between the genuine BM50 and BM57 a BM57 New it seems a better choice as you gain that 1/16 bore size with the BM57, I would be interested in how much difference you feel with the BM57 fitted. I am going to take SteveL's advice in the short term and see how much actually comes out of that proportioning valve vent and save up for the Genuine Nissan part. Thanks for clarifying the HFM failure

      Thanks mate. I just got the post inspection 1/2 done from state roads when the starter motor packed up, either that or the car alarm system is having trouble.  OEM part number 23300-AA112.

      Hi, I though I was coming to an end in finding a replacement starter motor for a rb25de neo. I came across a starter motor from Taarks and a message below stating: Direct fit. 11 Tooth count. All below part numbers have been superseded to 11 teeth. Can some body shed some light on going from 8 teeth to 11 teeth apart from 36-month / 25,000 km warranty for passenger vehicles to 12 Month Warranty. Compatible with the following Nissan part numbers: 23300-20P00 23300-20P01 23300-20P05 23300-20P10 23300-20P11 23300-AA111 23300-AA112 23300-AA300 23300-08U10 23300-08U11 23300-08U15

      J50 clock date suddenly reset to January 1

      Low battery? Maybe check capacity? I know first-hand, on BMWs if your battery drops below 80% capacity, it starts causing strange issues.

      8.5 +37 = should fit rear, but I think it'll hit on front. What you want is low 30s/high 20's front, mid 30's rear. That 17" screenshot you posted looks good, I'd run it on my R32 (but that's long dead now). For tyre sizes, my rule of thumb is: 8': 235, 9": 255. But that's just my opinion. Nismo sizes: 18x8.5+35/18x9.5+38 is a good starting point.
