Anyone install a Boost Gauge yet?

I was wondering if anyone have plans to install a Boost Gauge and if so, what brand and what location in your Spider will you be installing it?

Iv'e been wondering the same thing. Every time I need to do development, I have to string a boost line in through the window and tape the gauge to the dash. I really need to come up with something more permanent. It's a crime that Fiat didn't give us a boost gauge.

I read boost off of my Ultra Gauge. It is a digital display. Boost really moves all over the place when at part throttle.

Do you use the Ultra Gauge for your 0-60 times? Also, do you leave it plugged in all the time, so it can record things like fuel economy while you are looking at your smart phone?

Yes it works extremely well on 0-60 times and 1/4 mile times. I leave my plugged in all the time and use it as a separate meter to read certain parameters...one being boost pressure. Do not use it for fuel economy even though it has a more elaborate fuel economy setup than the 124 system does. I am quite happy with it as I have used several of these OBDII gauges in the past...this one seems to be the best so far.
Just keep in mind that anything reading boost through the OBD 2 port will not be accurate with a piggy-back device like Euro+Drive Lite. Also, many devices that read through the OBD2 port will not read above 22.6psi. So for certain applications, and actual boost gauge is the only way :(

Thanks, Greg. That is pretty much what I thought, since the EDL is measuring the actual boost, then modifying that signal before it gets to the engine control module.
Too bad some form of oil pressure gauge either.

It really is a crime. I've thought about doing a three gauge pillar on the side like most people do, but at the same time I feel like it can be pretty tacky and wanted something more OEM that would blend in with the interior gauges. I have seen some Abarth oil pressure and boost pressure gauges, but they only read in bar and have an orange backlight to them.
Yup... was aware of that. Would actually rather have an oil pressure gauge than boost. But that is not available through the OBDII port.:(
I think a boost gauge is more important. Oil pressure is never going to be a problem in this car. However mods make changes to boost, so it's nice to see that, plus sometimes the cars develop boost leaks or other issues you can see on the boost gauge.

Please post a link to that, I would love to see it.

It would be so easy for Fiat/Mazda to provide an "Instruments" App for the 7" display...

Not trying to hi-jack this thread... but why do you believe that oil pressure will never be a problem in this car? It's good to hear. I am not familiar with the internal workings of this engine and I am just curious of what about their system makes you think that. If you would rather pm me that is fine. Thanks for the info.;)

Greg,

Where are you connecting the boost line at for your gauge?...

I somehow missed this post earlier. This engine's oiling system is pretty near bulletproof. Plus is has an excellent oil cooler so the pressure stays pretty stable even when you do things that would heat up the oil a lot in other cars. I just haven't seen or even heard of any oil pressure related problems with this engine. Now I have heard of problems with the multiair passages getting clogged, but that's from not changing the oil.

Best place to put one is downstream of the turbo (duh) in an easily accessible area. You'll have to drill/tap a bung into the intake/Y-pipe and then find a creative way to fish that tube into the cabin area.

As for gauges, I'd recommend one of these:

http://www.ebay.com/itm/Prosport-Un...ash=item41b6f5f1bb:g:Ih4AAOSwcUBYGmm7&vxp=mtr

One of those colors should work well with the interior lighting scheme.

Unfortunately you will have to get creative with the gauge pod... No one makes a direct swap for the ND Miata yet.

I use a "T" to spice into some of the plumbing on the intake manifold. I don't have a picture, but I'll try and find one.

I am going to go with the Autometer Cobalt Mechanical gauge...https://www.amazon.com/Auto-Meter-6103-Cobalt-Mechanical/dp/B000CIH9KE/ref=sr_1_10?s=automotive&ie=UTF8&qid=1485448546&sr=1-10&keywords=autometer+boost+gauge...I like mechanical gauges when it comes to boost...most likely get a single universal pod and heat it up to mold it to the existing pillar shape...I have done this before and it usually works pretty good...thanks for your input:)

That will be great...a simple T is what I am looking for...thanks;)
