GPS Gauge Issue

[Papa]

Just a heads up for those with GPS speedometers. If you transport your car, make sure the shipper removes the key. Unless Mr. Kliener was joy riding in my car, which I doubt since it was barely running :p, my car accumulated almost 500 miles in a trailer.

Well yeah, the way it was running and gulping gas most of the time it was here 500 miles would have taken a several hundred gallons of fuel!!!

It must have accumulated the miles on the way here because I remember noting that it had 5xx miles on the odometer and was a bit surprised because I had the impression that it had not been driven much. The ignition would have to be on for the GPS to log speed/miles, right?

I'm envisioning Farris Beuler's day off with the transporter. Maybe he should have tried driving his truck in reverse for a few hundred miles...

Funny thing is though it was much more than 500 miles between you and me. Maybe because it was inside the trailer it was acquiring and then losing the satellite signal along the way. I bet that was "what the heck????" moment when you saw the mileage!

That's what I'm thinking. There are some other strange things that could happen with GPS regarding almanac message processing, but I would have expected a glitch there to show the full mileage difference. Who knows how Speedhut's gauge software works. I suspect if someone is concerned about it, they could disconnect the antenna during transport, which should eliminate the possibility of getting even an intermittent signal.

The good news is that the car is actually running pretty good right now and that's one less thing to have to deal with before trying to get my VIN.

I'm happy to hear that and think we can be pretty certain that the lack of sidepipes was causing the O2 sensor to report a lean condition. As I said though I've had a bunch of Coyote engined cars through here with their sensors in the same location that seem to run exactly the same whether the pipes are on or off but of course the ECUs are entirely different. No matter what I'm just relieved that you aren't going to have to deal with a sick engine (probably not as relieved as you are though :)).

Now wait a minute, you told me you had to test drive all the paint before you returned the cars. :rolleyes:

[GTBradley]

Look at it this way, you’re 500 miles closer to your engine break-in period...too soon?

[GTBradley]

Sorry, but seriously, was the key on that whole time? How did that not run the battery down? I mean it’s a two day trip, right?

Well, the battery was down. After a couple of short starts, it was dead.

Oh, Yeah!

Papa, I'm guessing that you hooked up the always hot wire for "faster startup" on the GPS. If you did, I'm guessing that that means that it is always tracking where it is at and thus added the miles. And as Jeff said, in the trailer, it was most likely not getting full signal all the way. Having the battery disconnected or the main power turned of I would guess would have prevented the extra miles showing up.

No, that's not the case. I've used the Speedhut GPS speedos on two builds, and use the hot wire on the GPS. Through the HAAT circuits in the Coyote harness, which aren't switched off by the master disconnect. Trailered both cars to Wareham, and also an even longer trailer trip to Texas last Spring. All with the battery connected. No unintended odometer miles were registered. According to the instructions, the only purpose of the hot wire is to "remember" the last position so that it has to search less and start-up is quicker. Which I've found to be the case. Usually it's ready to go right after backing out of the garage. Based on my understanding, the GPS isn't actually running or tracking the location during that mode. The current draw is extremely low. Speedhut lists it as 25 micro-amps.

The only way this could have happened, in my experience, is if the gauge was receiving full power. It is interesting, nonetheless, and something I'd never thought of. The GPS speedo doesn't know the wheels aren't turning. Only that it's moving. So if left on, the miles would register whether being driven or not.

Yep, thats correct, the GPS isn't active when hooked up using 'always on' just remembering last location.
