Anyone using GPS speedometer?
After yet another cluster failure, I'm looking at the Speedhut GPS speedometers.
Read a great thread about redoing the cluster with their gauges, but the GPS speedo was really what caught my eye.
1. Anyone have experience with these?
2. Will the stock tach still work with the OEM speedo out of the cluster?
3. Any issue with no ECU connection from the GPS Speedo?
I've tried the capacitor repair route, sent a cluster to DNA, tried another cluster only to have it start to fail. Thought about buying the new speedo from Ray, but the GPS is less expensive.
thanks for any insight

You may want to consider buying a JDM cluster, read my writeup(s) on that. You can convert it to show MPH, move your odometer reading into it, and calibrate it.
I don't get a real warm and fuzzy on that gauge, seems like in a year or so it'll be messing up and you'll just have a hacked up instrument cluster to show for it.
That said, the speedo and tach are totally independent in the cluster. If you take out the speedo the other gauges will be just fine.
BTW, if you buy a JDM cluster, get a '94+ cluster, you can tell them by the fewer hash marks on the gauge faces. The later clusters are much more reliable than the original '93s. And you will typically have less mileage on them as well.
Not to mention, if you just need the speedo out of the cluster, you have a good tach you can then sell to someone with a dead tach to recoup part of your investment.

Dale,
Does "black" rings instead of chrome mean anything on the JDM clusters?
Looks like there were several versions of the hash-marks especially on the tachs.
Any other clues to the age besides the # of marks?
I did read your thread and it was helpful.
thanks

The black rings are later clusters, 96+ for sure.
So, few hash marks = newer, black trim rings = newer still, boost gauge instead of oil pressure = newest.

Also my buddy had an MR2 and his speedo broke, he was too cheap to spend $200 for the sensor that broke so he used his Garmin nav unit that calculated mph. It was pretty accurate and only had problems on quick acceleration and deceleration. I would imagine this was due to the fact by the time the satellite tracked the movement it was already behind the actual speed but driving around town was fine.

If the inputs for the speedo and tach are different, Why do they often act up at the same time?
Does the Speed Sensor feed any info to the tach?
Just watched them go crazy together today.
Thanks

The lag seen on navigation GPS units is due to the GPS signal sampling frequency of the unit. Most navigation units have a fairly low sampling rate. Hence the lag. One would assume that the speedo has a higher sampling rate to make it more accurate. Racing data loggers typically have a higher sampling rate unit installed as well in order to give more accurate resolution of what the car is doing. You can ask Speedhut what the sampling rate of the GPS is.

jmirage04,
Did your tach work normal after the swap?
Did you put the gps antenna out in the open or hidden under the dash?
Any issues from having the speedometer Unplugged?
was it the 4" Speedhut unit?
Thanks
