i reply to you cos no-one has one or any experience with it.

i didn't want to fork over money just for a simple plug and play procedure.

my daily driving is @0.7bar ~10.2psi otb @ratio of 30% or 13.3psi as the profec a has a tendency to spike whilst the B version is a better unit but I'm not complaining. Much better torque in midrange and overall response than my bleed valve @12psi.

offset is if you want to align the profec a boost reading with a boost gauge as per manual. Not much use for me.

have you connected all your hoses up?

cheers

I only just got back from my first run after fitting the profec A. Like yourself I cant get it to go to P1 mode on its own. It goes straight to normal operation. However i did the alternate mode as per info from Greddy site. After power is on hold down power button for 5sec and you get P1 do what you have to and push button twice for P2. After only a quick tune the boost seems a little unstable. In lower gears at 1bar it reaches 10psi (4psi short) and reaches the required 14psi in 3rd and 4th.

I have two questions for you.

1 - Did you leave the back nipple with no hose to atmosphere?

2 - What pwr supply did you use? I connected to accessories which is anoying as the solenoid operates when accessories are on. I need a ignition supply. I thought of the pwr window supply. Also how did you earth it? To chasy, batt, or a nearby earth to something else.

Let me know how stable you get your boost any any tricks you discover. I am off for a good drive tomorrow. I will see how I go.

Hope this helps!!

Greg.

I will try the manual way to set it up but I thought it best to do it the normal way(whatever that is no-one knows apprently!!!!). I left the back hose free(once again the manual say's nothing about it). Pull the cigarette lighter out and use the PWR and Earth from that, its ignition pwr and would probably work better in the long run, in case you sit in the car using acc for the stereo etc.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
