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.

    • You are selling this? I have never bought something from marketplace...i dont know if i trust that enough. And the price is little bit "too" good...

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again?
