Prosport Gauges Have Arrived!!
 
4 Attachment(s)
Well I figured "Hey i am relatively new to the boards so what better way to give back then doing a review!"

So basics, I have a 1993 FD3S RHD, some minor mods. After doing some research on our awesome board I would add some gauges. I decided to go with Prosport for a couple reasons

First - Quality - All the reviews I have read have said good things about these guys (I even called and asked some questions) Hell they make the parts for other manufactures (from what info I can find)

2nd - Customer Service! - Customer Service is extremely hard to find these days it seems. I called Prosport and had a few questions regarding needle control (I went with the Performance line I wanted white with green lighting)

3rd - Looks - The gauges look very clean colours are crisp nice contrast between the needle and face and well what can I say I like something that when it is off it goes stealth (only contradiction to that statement is I own a 3rd Gen RX7, this car NEVER goes stealth lol)



So guess what came in today!! Yup you guessed it a nice big box full of gauges.
SO like any responsible adult I ripped into it to oogle my new toys. First thing I noticed was how well the items were packaged (I am way up in Canada so they had to go a long way)

So I got the package at lunch then had to wait the rest of the day before I could play with them. Well I have been home for a little bit now and got them mounted in a din plate, nothing to really note, very easy to install (which 52MM gauge isn't)
One thing I did not have a problem with is the instructions I have read that some people have a hard time with them, i took my time and did not have an issue. Just label signal wires and your set.


I will post more info once I have them installed and what not.

The gauges I went with are
Mech Boost Gauge (I had read that on some Elec Boost gauges the needle would not Zero)
Oil Pressure
Oil Temp
Water Temp
EGT / Pyro (I only went with one, then did some more research and found that I should run two, so the EGT will most likely wait until the winter when I can pull everything apart)

One other thing I noticed is that there is some bleed off from the red LED for the needle,( I can only see it when the green or white light is off) I am thinking I might use this to my advantage (long night drives, kind of nice to be able to turn the lights down)

nice job, looks good

NoPis10 03-09-10 10:34 PM

congrats....

I have had them on my 3rd gen for about a year and NO issues.. I just added a fuel pressure gauge last week and everything is great. I have the electrical boost gauge and it's worked flawlessly and zero's out fine... I have the following..
Boost
Oil Pressure
Water temp
A/F ratio
Fuel Pressure
Along with their 3 gauge pod for the dash...

MSilk 03-09-10 11:23 PM

That is my next add on, their pod for the center speaker.

Finster 03-10-10 01:01 AM

Looks good, I just recieved my boost, fuel pressure, water temp and triple pod from them.... Looks damn good, I must say.

There are gauges with superior quality out there, but, to each, their own.

pito13b 03-10-10 07:37 AM

My mechanical boost gauge is fine. I have an oil temp that has started acting up but I think it might be the sensor. Had them since December. Great customer service though, I emailed in about the issues I was having and had a trouble shooting reply back within 2 hrs.

I actually read the link David Hayes posted, I guess I should re word the statement " For the price these gauges are great" There were some others, I believe one was on the Subaru forum (I love google lol)
But one thing I kept thinking while reading the - reviews is that they all seem to be about needles off center (elec boost gauge, I went with mech) and senders messing up. I can see a sender going squirrly is they are only grounding through the block and not through the wire, also if you are grounding through the wire you ground point has to be clean(installer experience talking there, clean as in bare metal not just using the screw)

TwinCharged RX7 03-10-10 11:25 AM

Nice install, but PLX FTW!!! I'm going to love having only 2 gauges but being able to see 8 sets of data at once.

The PLX's are super nice way on the $$$ side though.

DaleClark 03-10-10 11:49 AM

I've installed Prosports on a project car I had. Basically, you get what you pay for. Cheap plastic gauges, cheap wiring harness, cheap sensors.

The gauges I had the boost sensor (it was the electronic peak/hold/warning gauge) went out with virtually no use on it. Had to replace the sensor. The water temp gauge wasn't accurate long-term either.

Nice Greddy gauges are VERY reasonably priced. I have a Greddy peak/hold/warning boost gauge and water temp gauge in my car. Nice metal cases for the gauges, quality senders, nice wiring harnesses, etc. Dead reliable, dead accurate, and have been so for 5 years now.

Again, you get what you pay for. Don't expect Defi quality in a $60 gauge - there's a reason Defi gauges cost so much, they're top of the line, all quality parts, thoroughly tested and verified to be accurate.

Think of it this way - a few pounds of boost one way or the other can mean the difference between a fun car and a blown motor. It's not worth cheaping out on gauges.

Dale

Turbo8 03-10-10 12:05 PM

I had ProSport gauges on my old project car, and like others have mentioned, you get what you pay for. They are a decent cheap gauges, but just that- cheap.

My water temp gauge was pretty inaccurate, and the electric boost gauges are notoriously inaccurate and super slow to respond.

For my FD this time around I went with AEM's new Analog series of gauges, super high quality and very accurate. They aren't much more than ProSport's, either.

MSilk 03-10-10 12:10 PM

To each their own, I like the look, I am going to be testing the sending units today at work to see how accurate they are, I will post my results. I agree that a full compliment or DEFI would be awesome, but for me and what this car will see for use I feel the Prosport will be more then what I need. I will post my test results later today.


Mike

MSilk 03-10-10 12:44 PM

Well it was bugging me so I did a test on the boost gauge right away lol. so here is what I found after doing 3 tests of just pressure and 3 of vac. I then alternated between vac and pressure.

under pressure (boost) the mity vac and prosport were dead accurate, what I did find is that the needle would hesitate just a bit, but would stop on the same mark are the mityvac.

Now under vacuum... the prosport was off by 1 consistently Mityvac would say 10hg gauge would say 11hg. The needle would not rest on 0 after a Vacuum cycle (cycle would consist of 0 - 20hg - 0) Needle would be accurate with boost even if it did not zero under vac (I am thinking that the zero zone is larger then the face allows for so the needle looks to be off of zero)

I will try to get to temps asap, I will post my results

Had you opened the thread, you would have seen that the thread has very recent updates in it with negative reviews about product quality, longevity, and accuracy. That would have required effort though (he says sarcastically):)

Finster 03-10-10 12:56 PM

Having a pfc+commander helped my gauge decision. By all accounts the commander tracks the basic gauge stuff well. So my Prosports are a secondary visual aid of the basics.

If I decide to get gauges like EGTs, wideband o2, etc I would likely shell out for top quality, as those gauges would be used more for tuning.

prosport Gauges 03-18-10 11:07 AM

Hey guys, Its Ryan from prosport.

I just want to point out the thread david hayes posted up shows a thread from 2007. I mention this because we have updated many items and sensors since.

-Premium boost gauges are now adjustable up to 1-2 PSI depending on Elevation. (starting 1 year ago)

-boost Sensors were revised as of 1 year ago. Much more accurate and durable (Although they are not water proof).They may look the same but the ICB is much different.

-Water temp sensors have been replaced with a new sensors (Now on shelf shipping). WAY faster responding and accurate to about 1-2 degrees.

As we grow we have made changes and take feedback from you guys and many other forums. We have been makeing gauges for over 30+ years and quality/control is top priority.
We do use the latest Swiss stepper motor movements and air core components. We will stand behind out product and help anyone out

Thank you for all the feedback.

Ryan

I only saw 1 person with a recent post about Prosport gauges not working. Seems that they only lasted 10days and stopped working all together, my guess would be a fuse or wiring issue. There is also a few links to other boards that are from 2007 as well, seems to be a ruff year. The rest of it is talk about PLX and for the money you spend on them they better work right. Hey buy what you want but any review should be taken with a grain of salt.

I bought a gauge from a company out of Taiwan that isn't even sold state side.

Thanks for the updated info..

As of today, ALL 5 of my Prosport gauges have worked without fail....
My water temp gauge is very accurate. I have a PFC and the temp on the PFC is within 1-2 degrees of the readings of my prosport gauge.
The boost gauge is also within 1-2 lbs of the PFC so I am very pleased as of now.
I will say that the only thing I feel Prosport could do better would be to make the wiring thicker. The thin wire is hard to work with when trying to extend it's length.

BTW.. I daily drove my FD for 6 months for work averaging 60-100 miles a day in city trafiic as well as getting in and out of the car on average 5 times a day..

Hey Guys I got three of them installed, Water temp, Boost and Oil Press, They look great everything seems to be working 100%. I will get some pics up asap (I am at work right now).

Hey Ryan thanks for all your help and dealing with me and all my questions/brainstoming LOL
Do you guys have any plans on adding a Oil press gauge that goes to 150? (the 7 pegs the gauge when cold) or do I have anything to worry about with the gauge being pegged, will anything fatigue sender ect?

Oh and I will be getting the center speaker mount soon, i will let you guys know how it goes.

Will do, as Ryan says the pod can be moved to face us RHD people! I should have one here soon and I will let you know from there. The three gauges I put in so far are in a DIN panel I think it was from Glow Shift (I wanted the 3 stepped version) All I did so it would face the right side was flip it over and it works great and looks great. I will add some pics tonight.

Yep.. That happens with the oil pressure gauge only reading to 100..
I thought there was something wrong till I found out that the FD's oil pressure is higher than 100 when under load. When at idle, the Prosport gauge is right where it's suppose to be...

prosport Gauges 03-18-10 04:06 PM

All of the premium series Oil Press. gauges read up to 150 psi

http://prosportgauges.com/

ifryrice 03-18-10 04:07 PM

I've got a pair that are a couple years old, they're the peak/hold/warning style. The water temp gauge has been working perfectly (and has been accurate as far as I've ever tested). My boost gauge on the other hand almost never sets to 0, it's always slightly below. And every once in a while for some reason it resets in the middle of driving and wherever the needle was at that time now becomes 0, for example, if i was under boost at about 4psi, the vehicle will start reading vacuum at that point, and when turned off it'll read 4psi, under boost it'll read 14psi (which is actually 10psi). It'll behave like that until I power it off completely and let it sit for a while and come back. I've tried rewiring the sensor, relocating it, all kinds of different things and it still does that. If I could figure out why it doesn't 'zero' properly or fix it from zeroing while driving at a random reading I'd be pretty happy with them. It doesn't even do the usual behavior like they do when powering on (sweeping/beeping), it just starts reading from that random position.

Enervation 03-18-10 04:31 PM

These appear to be rebranded all over the world. Here in NZ they are primarily sold as Autogauge, but we also have a few other brands that stick their logo onto it.

I have this one:
http://www.autogauge.com.tw/web/prod...tegorySubID=70

while the pic only shows the white backlight variation, there are about 5 other models that have various colours (one even allows you to choose from 7 different colours).

Compare that to:
http://prosportgauges.com/images/view.aspx?productId=87

so its pretty clear they are the same.

So my point is, the Autogauge brand has been around in NZ for a long time, and while its known as the cheap and nasty option, it does actually work, and is relatively accurate. They don't look half bad for their price too, but certainly aren't in the same league as DEFI.

You forgot about me! I'm +1 good, +1 bad (possibly boost sensor?, but it's done it ever since I've owned the vehicle, and the gauges were less than a month old at that time) I guess, though semi-old.

I can count atleast 3 bad oil pressure sensors, 1 bad boost sensor, and 2 bad EGT sensors that were bad coming out of the box....and thats off the top of my head

Spend the money and get something worth while

ifryrice 03-18-10 07:28 PM

What were the symptoms of the bad boost sensor? I've been trying to diagnose my issue for a while, was about to just replace the whole gauge, but I hate to replace the coolant one with it since it works fine... and non-matching gauges look bad usually.

MSilk 03-18-10 08:31 PM

Hey Guys umm I would like to point out that this thread (yeah the one I started) was not about "i guess i should have bought DEFI gauges" or any other variation of different brand of gauges. IF I have any problems with them I will post and let all of you who have issues with Prosport say I told you so.
I have been in retail for 10-12 years be it selling Car audio or alarms or selling TV's to auto parts. I can honestly count on one hand how many company reps that are as helpful as the guys at Prosport and are also willing to STAND up and say "Yeah there was some issues with "xxx" product we listened to you the customer and implemented a fix.

Now do not get me wrong I appreciate all the input be it good or bad and I would like for everyone to chime in but please keep it constructive. (ie no "They suck" with no reason for your opinion ect) so far we have been on the right path :)

Now to get back to what this thread was supposed to be about.

Like I have said the gauges are in and look great! (maybe I have cheap taste or insert what ever funny ass line you want) but I honestly like the look of these gauges. Now I have only had them in the car for a few days and I have yet to put any miles on them so as I find out more I will post and inform.


Thank you everyone
Mike

Defi's are always a nice option.

Juan 03-21-10 12:39 AM

ProSport has great customer service but their gauges were pretty crappy when I bought them in 2007. I bought their top of the line ones and they were very cheap. I havent seen their revised gauges personally or know anyone with them so I can't say if theyre better or not but I don't think I'll buy any anytime soon.

Their customer service reps were helpful and replied to all their emails very fast. Too bad other companies arent always this helpful.

Ottoman 03-21-10 04:37 AM

Defi gauges FTW:

https://farm4.static.flickr.com/3315...582902d5_o.jpg

Finster 03-21-10 01:37 PM

^ Didnt the OP just point out that this is not a "I shoulda bought Defi" thread. Any EXPERIENCE with prosports good or bad should be posted.

EVERYONE knows Defi is the best. End of story. For those of us on budgets, basic gauges such as water temp, boost, and fuel pressure cover items that Mazda didnt without breaking the bank.
Everyone's recommendation on this forum is almost always to buy the top dollar item. That's easy to do in cyberspace where there's no financial responsibility. This forum serioously needs a "Best Bang for the Buck" thread
I'm curious to see if the OP's experience stays positive.

Juan 03-22-10 04:56 AM

I would get VDO gauges instead. VDO makes the gauges for Porsche, Lamborghini, BMW and more. Their gauges arent very flashy but theyre cheap and reliable. I don't think I've ever heard of anyone complaining about VDO gauges before. Theyve been around for ages as well. I'd buy these over ProSport if I were on a budget.

If you're set on ProSport, I'd say these gauges will work fine if you're not looking for 100% accuracy but need something more accurate than the stock gauges. ProSport wont break the bank and they dont look that bad.

prosport Gauges 03-22-10 08:51 AM

Everyone is entitled to their own opinion and that makes for healthy competition. Since 2007 we have made changes to our gauges and senders. The Stepper Motor movements in our premium series comes from Switzerland, our boost sender IC's come from motorolla (USA). and temp senders has also been ugraded. We worked side by side with Bosch to develope our wideband AFR gauges using their latest O2 sensor with the widest range on the planet. So, alot has changed over the years.
We are here on the boards to help with tech advise and support of our customers and vendors. Feedback (good or bad) is always important to us. Their is no better place to get honest opinions than on the forums.

I bought them back in 2007 and never had an issue from day 1. You can spend $400 on Prosports or $1200 on Defis....it was a no brainer for me this go round. I did have a full set of Defi back in 05 and loved them too as they matched the stock lights perfectly.

I just ordered another full set of ProSports 2 weeks ago for my current buils.
