    HELP with Boost Gauge Model# W/ Max Boost recall function

    Hi,
    I have something a little unqiue Im trying to get and that is a Boost Gauge w/Peak hold/Max Boost recall function.

    I have read that Autometer does make such a device and therefore it should be plug and play to the Autometer Ultralight I currently have installed.
    http://www.autometer.com/

    I like the UltraLight II setup with its more visable color scheme but would really enjoy seeing how much boost Im putting out on a give run... even on a given strech of the track...(corner to corner)

    So for I have found this guage which can definetly do it but it will not match the other gauges in the center console... (I have the cigerrette lighter delete...)
    http://xxtuning.com/xxstore/product_...roducts_id=226

    A quote on another forum spoke about The Blitz boost gauge:
    "It will hold max boost for certain intervals, so you don't have to constantly watch your gauge for the peak. It also has a recall for max boost for any given time. It will also record 90 seconds of measurement if I'm not mistaken. It's quite a nifty littly setup "
    ...but it also mention:"the Blitz gauges do need the control unit, but only once. After that you just plug the gauges into the unit."
    Im not sure what that means....
    http://www.blitz-uk.co.uk/gauges.html

    MIRROR DRIVE METER

    The most distinctive gauge to have been produced by Blitz, the Mirror Drive meters are brightly backlit and have a mirror face when the vehicle ignition is switched off. A full range is available (boost, temperature, pressure, and exhaust gas temperature) and the gauges are 60mm diameter and come with either a carbon or white face.



    I'd prefer to go with Autometer.... cost being one reason....but really need help with which model # etc... offers this feature....

    I'm not sure on the details here, but I believe the ScanGuage II has a memory feature.

    It monitors boost as reported by native sensors to the EEC under the lable MAP..."Manifold absolute pressure". I have the ScanGuage I, and it consistently reported my boost with more accuracy than my analogue Autometer gauge, but did not have any recording features. The II is supposed to collect and hold as much as 90 seconds of detail, and be able to download to a lap top. Member Mike has a II on order, I have to check that out.

    I jave a II Mac... how do you figure the boost? do you take the reading at 0 and find the difference? cuz at 0 on my gauge I'm seeing 16 or something via the scan gauge... so how do you find the boost amount from the absolute number?

    I know you're looking for reasonably priced gauges, but you might want to save up for the AutoMeter Nexus line. These have a controller that has an SD Memory card slot and can record whole laps, heck, even hours of data. I've got them and I can record the entire trip to Wal Mart and back, and then replay it either on my laptop or right on the gauges in the car.

    You can press a button and see the peaks of every gauge until you reset it, and they can be programmed individually to change color in a danger situation; Low fuel pressure, low oil, too much boost, too high of water temp... That too is recorded and can be played back. Tie that into their tack and speedo and you can really see how your car reacts if you're going for the logging type of thing.

    Just be sitting down when you order them. A good set of 5 gauges and the controller will run you about $1500.

    I'm saving up for the new controller so I can add the Speedo, Tach, Fuel level and Wide Band gauges to my set.

    ouch.... I would really just like to get my max boost without having to look down at the gauge while Im nearing max boost... Its just not the safest thing to do...

    Even if the setup was as simple as pushing a button and the highest seen boost shows up on the gauge......

    MAP registers in PSI, what do you see at idle? I see 4-5 PSI at idle and I just subtract that from the top number. Maybe I'm looking at it wrong, but the numbers did corelate when I had it plugged in to the #1x.

    Yeah I see I think Maybe 5 or 6 at idle, it seems like I was seeing like 16 at no vac no boost, and the analog gauge however I have to admit that I didn't look at it in wide open, and I keep forgetting to check what it said was my peak, I think it reading pressure at idle kind confused me, since I didn't know how to derive common figures from absolute ones. When I get my car back from VT I'll check again :-D

    Usually boost/vacuum gauges indicate above atmospheric pressure in psi (pounds per square inch - gauge) and below atmospheric pressure in in. Hg (inches of mercury).

    The conversion from psia to in. Hg vacuum isn't an easy one to do in your head, but here's a cheat sheet:

    0.00 psia = 29.92 in. Hg (100% vacuum)
    0.49 psia = 29 in. Hg
    0.98 psia = 28 in. Hg
    1.47 psia = 27 in. Hg
    1.96 psia = 26 in. Hg
    2.45 psia = 25 in. Hg
    2.95 psia = 24 in. Hg
    3.44 psia = 23 in. Hg
    3.93 psia = 22 in. Hg
    4.42 psia = 21 in. Hg
    4.91 psia = 20 in. Hg
    5.40 psia = 19 in. Hg
    5.89 psia = 18 in. Hg
    6.38 psia = 17 in. Hg
    6.87 psia = 16 in. Hg
    7.36 psia = 15 in. Hg
    7.86 psia = 14 in. Hg
    8.35 psia = 13 in. Hg
    8.84 psia = 12 in. Hg
    9.33 psia = 11 in. Hg
    9.82 psia = 10 in. Hg
    10.31 psia = 9 in. Hg
    10.80 psia = 8 in. Hg
    11.29 psia = 7 in. Hg
    11.78 psia = 6 in. Hg
    12.27 psia = 5 in. Hg
    12.76 psia = 4 in. Hg
    13.26 psia = 3 in. Hg
    13.75 psia = 2 in. Hg
    14.24 psia = 1 in. Hg
    14.70 psia = 0 in. Hg and 0 psi (0% vacuum)
    15.70 psia = 1 psi
    16.70 psia = 2 psi
    17.70 psia = 3 psi and so on...

    5 psia at idle would be about 19.5 in. Hg, which sounds about right. Boost in psi would be your max psia reading minus 14.7

    While we're on this tangent, does anybody know where the MAP sensor is mounted? I've never looked for it. It might come in handy as an aux input for my WBC a/f gauge project.

    There are two versions, the 15 psi and 30 psi. Which do you need? I have a 15 but am planning to upgrade shortly.

    Google is a wonderful tool.

    To roughly calculate vacuum on the fly, take your MAP reading below 15 psia, double it, then subtract it from 30. That will give you in. Hg vacuum +/- a smidge.
