I was looking at these gauges for my imaginary build and I saw the GPS speedo. It has a lot of features, including peak speed, 0-60, and 1/4 mile time/speed. I was wondering how accurate you guys think the extra features are? I know that GPS speedos are usually more accurate than stock in dash speedos, but do you think the 1/4 mile timers and such would be accurate?

I don't see why the 0-60 and the 1/4 mile wouldn't be. A gps should be able to accurately measure those things as well as know when movement starts and stops.

$750?

dont you guys buy whole cars for less than that down there!!!

I wouldent trust it at all...

I have one (it wasn't $750, that's for all 7 posted), my thread is here:

I don't have time to get into detail but I did test out the speedo in my wife's car using a motorcycle battery, and it was very accurate compared to her speedometer and the portable in-car GPS unit. I'm waiting to get my Fiero back, I'll install then.

Had a gps speedo on a go fast boat I owned - very accurate - easy to do speed to distance runs - would put one in an auto without hesitation.

i wonder how hard it would be to put that speedo in a stock cluster

I would imagine it would be Much more trouble than it would be worth - wanna have to mess with the 25 year-old plastic printed circuit ?

I would like to imagine these aircraft-type guages in my car (maybe someone will post the pic from this link)

I am a proud owner of both the GPS speedo and Tach from Speedhut. They install in the dash with a bit of modification, and can be ordered with the Fiero logo printed on them. I do, however have to admit I have not yet seen my dash. I am currently deployed and my friends installed them. They said there were no issues with the install. They are not 700 bucks. Just my 2 cents.

That price is for a set of 6 gauges, but I agree that shopping the sales is the way to go.. My main question was whether anyone had any knowledge or experience regarding how well the extra features work.

Alltrbo.. have you tested the extra functions?

I have a cautionary warning, not from real experience, but from past GPS knowledge..And that is it will not work in tunnels and heavily forested areas. If the GPS signal is blocked, the gauge probably doesn't work well.

(usually this is fine and typically not a problem in a boat or airplane)

I live in cornfield USA...rural midwest. Besides, I generally gauge my speed by engine sound unless there is a cop following me. Definitely good points to bring up though, thanks

Yeah, a little bit. (Everyone keep in mind that I have lots of satellite access as well, here in the DC area. YMMV)

I set the 1/4 mile timer at a stoplight and it seemed to count the distance and trap speed accurately, though it wasn't at WOT.
I had my wife do a WOT 0-60 run (she was driving, I was playing with the gauge 'setup'). I forget what the time was but it wasn't fast, she has an '09 Civic. It seemed to be as accurate as it should given a slightly uneven elevation.
The top speed recall worked as described, I reset it several times just for the heck of it.
Elevation seemed accurate compared with other elevation readings I've seen or taken.
Direction heading worked fine, but as with all GPS, you have to be moving for it to work properly.
Not sure why, but the clock was an hour off, annoying. My guess is that something in the loop didn't account for DST at that time.
"Hot Start" seemed to work fine, but took more like 10 seconds rather than 2-3 as advertised, IIRC.
We didn't go under tunnels or beneath heavy shrubbery so I can't comment on that though I'm sure tunnels will kill the readings, but it didn't drop out anywhere we did go.

The one thing that annoys me the most is that they don't tell you that it doesn't work below 5mph. Once you get to 5, it just jumps from 0 to 5. That's not really a big deal on its own, but it has me concerned about the odometer. If you're stuck in 0-10mph stop and go for 15 miles (it happens all too often here), will it lose all of the distance covered below 5mph, or will it compensate based on the locational advance? I didn't get a chance to find out during the drive (we were actually going somewhere, heh). That can add up on the regular odometer over the course of all miles driven if it doesn't count. An alternative is to try to keep the factory odometer hooked up (the mileage will still read accurately then anyway, since it doesn't have to start from 0 like the new speedo, though I don't remember enough about how it works to find out if that's feasible considering that the factory speedo won't be there).
I've been meaning to call Speedhut to clarify...

Overall: From my short time with it so far, I think it is worth it for most people because of the speedometer accuracy vs. stock 25 year old junk that often has different size tires installed anyway, and because the extra features are either useful or cool, or both.
If I find that it doesn't suit my needs over the long term (if I have lots of issues on twisty mountain roads, etc.), I will install it on my motorcycle because it'll be perfect for that, then I'll get a 'regular' Speedhut speedo for the Fiero. I don't foresee that happening though.

I hope this answers some of your questions. Hopefully I can give it an installed full eval before too long, my Fiero is almost ready to come home from The Haus.

The GPS speedo is far more accurate than the one in the car. One of mine even reads out your speed in tenths of a mph. Ones in some of my cars have been off 5-10 mph even with oem tires. Just wearing down 1/2 of the tread alters the reading. My Coronet didnt have a working speedo and GPS was what I used.
