The level setting is a % of maximum, not the actual boost. Start a low setting and work up from there.

You can find my settings here, I'm running 1.4bar on an SS2: https://www.sau.com.au/forums/topic/23649-help-required-on-using-my-blitz-dual-sbc/?do=findComment&comment=7801321

Are you replacing an existing boost controller or starting from scratch? If latter, make sure your tune is providing enough fuel for the boost level you want to run.

EDIT: Mine's the older model, your settings may vary but I'm guessing the logic might be the same

Hi did anyone sort this out as I have the dual sbc type r and my display does not flash and I cannot set desired boost pressure as per the instructions. Only duty, gain and p gain. Or warning boost pressure and limiter. Is it just full boost and you only set duty, gain and p gain and then warning boost pressure and limiter?

Duty sets the boost level.

The duty number != boost, it is just a number between 0% doing something and 100% doing something. More number = more boost.

Gain and p gain are used to help account for boost creep or drop off. The details vary from controller type to controller type (ie, the Profecs use similar terms but achieve their results slightly differently.) The manual should explain all that.

These controllers are dumb in that they do not control to a boost target. They are open loop. You need to adjust settings until it is doing what you want. If the performance of the motor, boost control system, elevation, weather, etc change, then the boost can and will come out to a different result on the same controller settings.

      Has anyone put in brand new full carpet? (not floor mats)

      By Yeetus · Posted

      Only needed to pull out the seats, center console and gear shifter surround, took a weekend and a fair few beers. You get to look forward to finding all sorts of weird shit under the seats and carpet, I pulled out a Chinese dudes passport from 2003, 220 yen and a condom wrapper 😆

      Well, turns out not a lot happened from back then to now, between life again, and working on 3 separate other cars (only one of which was mine, and will now be departing the household soon).   So I decided with the whole "don't go outside, it's a cyclone!" Turning in to being not a whole lot, I ventured down to the garage, found a couple of water leaks in the shed (the main one I've already fixed), and then ended up "stuck" as it started pouring rain, and I didn't want to walk back inside in the pouring rain. This meant I ended up taking a look at the Skyline, and trying to work out what past Matt had been upto. I retraced a few things out from scratch, added the rest of the power feeds in that I needed for the indicators, and headlights. Double checked I'd wired a few things up correctly (and worked out how I wired a few things to begin with), updated my sparse notes. Added one of the ground points. Oh, and got really really dusty, as the car is quite dirty. Wrote up quickly what should be left for me to do with the wiring too. Adding the below photos more for my records than anything else. I need to make myself a proper book for the car that details everything, and how I've done it, but for now, this is my records... The third image is my most important one for me, and I need to draw it out into a proper schematic eventually. The last photo is my re-written list, I'd have put it on the white board, except I had to take the white board down to fix one of the water leaks.
