Hiya guys,

Can anyone here help me out... looking for a picture of how your blitz boost controller (mine's a dsbc) is hooked up (on the solenoid side of things). I think i've got it sussed, but just want to have a look at someone else's to confirm what goes where.

Thanks heaps in advance.

hey mate i cant get a very good pic of it too cramped.. but ill post up what i got and i drew a diagram too....

the manual does show a good diagram too... i'd say you should have it set up right its pretty easy.... now just to tune in the boost settings thats the hard part....not really!

Thanks buddy! :( Can't really tell from here what's what, but i think i'll be able to guess it.

Btw, what have you got your gain/ratios/limiters set at?

Gain should be as high as possible to maximise response, but not so high that it spikes :P

Depending on the version of the dsbc you have you will either have 1 or 4 gain settings.

If you have 1 (original dsbc) then set the gain on your lowest boost setting. Start by setting both gain and duty to 5. Drive it (floor it in 3rd from 2k rpm) and see what boost spikes to. What you are aiming for at this stage is to get the spike up to just below where you want your boost set so adjust gain only. What you should see is boost spike up to say .8 bar and then drop back to .6 (assuming standard actuator). Once you are there adjust the duty up slowly. As you adjust duty the spike may creep a bit higher so you may have to drop the gain fractionally as you increase the duty. What you are doing now is bringing up the set level of boost up from .6 to .8 so you should get boost response that jumps up to .8 and then stays there. Definitely no spike at this stage.

If you have 4 settings then follow the above for each setting. It's easier than it sounds, and once you get the first one set the rest are a walk in the park.

I'm assuming stock turbo so you're aiming around .8-.85 bar? If so then initially set your boost cut at about 1 bar with a reduction of about 5 as you don't really want it intruding on setup unless you get a really nasty spike. Then drop it back to about .9-.95 once you have set everything.

No point having a boost controller if you aren't making it work :)

Hopefully that made some sense to you?

Thanks heaps dave ... that made perfect sense to me. It's an amazing piece of technology isn't it, i read through the manual three or four times now and was surprised at the things this controller can do for you.

I'll have it set up and tuned properly once i've securely installed the solenoid, just waiting on a blitz pod filter so i can make a box up and mount it off the side of that. Will let you guys know how i get on with it.

Cheers

Okay newbie question... could one of you guys please tell me if this is correct?

I've got a picture showing the stock setup on the 34. Do i need the in and out from the blitz solenoid to go where i've got the green arrows pointing too?

I think you have it right from what i can see. Someone more familiar with r34 plumbing may be of more help.

The pressure signal goes to in (I'm assuming you have pointed to the pressure signal but can see where it connects to the intake piping), and out goes to the actuator (which you definately have right).

You can then remove all the factory boost control hoses and solenoid.

Thank you BHDave.

I've taken a closer image of the first line...

Does this help confirm that the first line is correct? And do i just block up what isn't used after that?

Much appreciated.

Marked up your picture.

In and out to the dsbc, blank off the other one.

It's a bit of an educated guess but i figure the larger pipe coming off the side of the tee is the boost signal, the other large one definitely goes to the actuator and the small one marked blank is the bleed return line from the factory boost controller. The other small line off the tee should go to the factory solenoid as well and will be redundant once you remove the factory solenoid.

hope that helps.

      J50 clock date suddenly reset to January 1

      Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).

      Yuh, if it's 45°C outside, my car is driving in it.

      I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating.

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.
