I like mine.

But, if you can handle the ricey screen (I would mount it invisibly under the dash or in the glovebox) I would have bought the AVC-R insted of the Boost kit.

Reason? I'd just like to be able to adjust the boost in first gear.

I know everyone, myself included, normally says "Adjust boost with right foot" but I can now see the merit of having adjustable boost according to speed.

Would be great, especially during drag racing testing, to be able to add 0.5 psi at a time to first gear to try to eliminate wheelspin.

my $0.22 cents

Hmm - let me be the first to set a cat amongst the pigeons

I don't like mine

I have a mildly modified R32 GTR (~300awkw) with PFC + EBC and in hind sight I wish I had spent the extra ca$h up front and gone for the TurboSmart eBoost

It ?may? be just my tune - but I find mine does NOT hold even boost once I hit the max boost setting. The boost line waves all over the place – IE it varies +/- 1psi across the rev range.

Again – I don't know if this is the EBC or not – but that's what I get :)

I've seen other dyno graphs that are as flat as a tack once they hit the max boost setting

I also find it VERY noisy, it rattles/chatters like the clappers. That ?may? also be due to the fact that mine is mounted high on the passenger side fire wall – which makes it very easy to hear from inside the cabin.

If nothing else – this will give you something to think about

that's my 2c worth :mellow:

To get stable boost you need to have reasonably short hoses to the actuator.

If your's is on the firewall its probably too far away.

If it is installed closer to the turbo(s) ie, the passenger side strut tower, it should control boost better.

(and be quieter)

Although I know nothing, I have spoken to a tuner who doesn't like th PFC add-on, he prefers the AVCR. His reasons were, (AVCR has ) stabler boost, easier to setup and tune, with option of ironing out spikes at specific rpm, more functions. Though it might have been worth a mention.

Great unit, its the same unit really, i was missing the PFC sensor kit so i bought the AVCR one as its the same. Basically its the same without the rice blue screen.

And mine keeps boost very well.

so - any other suggestions as to why my unit does not hold a steady boost ?

If you have a nice stable consistant wastegate then their good but if not use an EBC with its own MAP sensor.

The Boost Control Kit comes with a MAP sensor, the same MAP sensor as the AVCR.

The Boost Control Kit solenoid is the same solenoid as the AVCR.

That would be a lazy tuner. I would say the tune on the engine is substandard or it has other issues causing the boost to fluctuate. Instead of fixing the real problem, he prefers to stick a band aid on it. Use the boost controller to cover up for other issues that really should be fixed.

Technically speaking, boost is load dependant, not RPM dependant, so making boost corrections based on rpm points is not correct. It might smooth out the boost curve on the dyno, where the load and gearing is exactly the same every time. In the real world, that is simply not the case, where boost is very much gearing and load dependant. For example, you could be applying a boost correction at 6,000 rpm in fourth gear that is simple wrong at 6,000 rpm in second gear.

Next time someone tells you that rpm boost correction is a good thing to have, ask them to explain how they get around the effect on boost of differing loads at the same rpm.

:D cheers :D

I am also curious. Would it be better to spend the $$ on the kit or buy say a Blitz Dual SBC Spec R which I have not found onje bad review for.

The Spec R is dual solenoid and everyone says that its the best controller out there.

I have read mixed reports about the AVCR and its reliability. This would then flow on to the boost kit since they use the same components.

How much boost are you running?

What turbo?

What is the wastegate spring pressure?

Maybe you are trying to bleed off a bunch of air. Could be remedied by a bigger wastegate spring....

R32 GTR with freash forged motor and R34 N1s - running (only) 1.2bar (18 psi). Using the std N1 actuators (waste gate spring ?)

i always doubted the avcr "gear boost" functionality, thanks for clearing up

Get some street R series tyres and then you wont have to worry about hi boost in lower gears.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
