Hi guys, so my battery died today and once I jumped the car found the boost controller settings was reset. All I remember was that it was set on Hi setting with dyno sheet showin 19psi that was set by the tuner. Now I've searched the forums and google but couldn't find anything close to my setup. I have stock motor with cam gears, exhaust, haltech platinum pro ecu, -5 turbos. Was making about 290kw at the wheels.

Can any one with a similar setup help me with the settings? I've taken a wild guess below, are they close?

Set: 30%

gain: 10%

set gain: 100kpa(14.5psi)

warning: 150kpa (22psi)

limiter: 10%

last highest boost reading was 158kpa(23psi)

Any help would be much appreciated, as I don't want loose performance or blow up the motor, please help!

You won't need to tune the engine, just need to get the boost controller set up again.

FWIW, the settings you listed above will probably get you most of the way there. Just make the Set value give you the max boost you want and adjust the gain value up or down to deal with boost rise or drop off in the top end. Adjust Set Gain to give you how aggressively it comes on.

Just make small adjustments and drive it around until you're happy with it.

Thanks guys, gonna drive around with the basic settings then and ring the tuner on monday. Hopefully they have the settings stored on their computer. Just surprised the boost controller doesn't store settings with battery disconnected.

It does store the settings with power/no power, etc. I've had the same boost controller.

The control unit only has 2x wires for power, GND and IGN - there's no constant power.

You could easily figure out how to set it yourself, the lower the GAIN the "lazier" it comes onto boost, the higher the GAIN the "harder" it comes onto boost but will have the tendency to spike.

SET just determines how much boost you want to run, please note SET the scaling does not equate to any boost figure.

Hi guys, so I spoke to the tuner and they were happy to help, we went for a quick drive and he adjusted the value within 5 mins and no charge as well. Seems my initial guess was close, set was bumped up to 37%, gain 20%, and limiter 5% so boost don't drop too much when it hits peak. I've recorded the values for future references.

Thanks to you guys for all the help!!

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
