use your phone and get a gps app

How can we make this work without:

1) Having to remove/reinstall the phone each time i drive.  i can get a 2nd phone, provided it's not as expensive as getting a new gauge.

2) Having to turn the phone on and off each time i drive.  Is there a way to wire it in so that it will recharge?  Or can i use a car charger?  Will this draw on the battery when parked?

The cheapest GPS speedo i've seen is at least $300.  i'm not saying i won't go that way, but i don't WANT to.    Really i just need an accurate odometer.  i can go back to the stock odometer, but it's not as accurate as the digital speedo i've been using all this time.

what what what? download the app on your phone. turn the app on while youre driving then close the app when youre stopped driving. if you want to reset the data you can at anytime.

i know that a lot of times i'll ask for something, then turn it down.  But maybe we can all use this as a learning experience?

So what happened was i thought i would at least try to fix what was wrong with the gauge, if i possibly could, rather then to try/buy something new.

So in checking all the wires, the temp gauge wires, both ground and positive going to the gauge were loose.  The temp gauge was acting up too, but i didn't think it was a big deal since it would only be for a second or so when i applied the brakes ( i assumed it was because i was low on coolant and the coolant would surge forward and the gauge would momentarily go to zero since the sender would then not be touching the coolant.  But it turns out that was not the case).

i have all my gauges on the same ground circuit and power circuit.   So i tightened up all the wires and knock on wood, the tach/speedo gauge as well as the temp gauge have not acted funny since.


NOTE: Not accurate ( i think the gauge was missing around 90 miles this time)

Even though I never calculate fuel mileage, it is good to know that you are attempting to track yours and display the results. I am sure this info will help people in the future looking for data as well

I find it informative to keep track of fuel usage, I always use the trip meter between fill ups, and mark the cost of fuel. Had a fuel issue with my jeep once-temp switch went, so it remained on cold fuel circuit, seemed to run fine, but mileage went down, only like 2-3 miles too, and if I hadn't been writing it down I might not have noticed.

I like this thread, I find it cool to the steps run out and the results posted.

Sure beats mine.  I have a 1974 Chevy K10.  3.73 gears.  35" tires.  4" lift.  350 engine.  NP203 t-case.  TH350 transmission.

Filled the gas tank to full.
Went 53 miles before having to fill up again.  Put in around 13 gallons.  Thats 4.38 MPG.

I need to try it again because this was going through mountain passes here in Colorado.

MPG, Part 2

In the meantime, here is an interesting read concerning MPG, specifically regarding RPM:

http://www.oldsmobility.com/old/carlife_apr67.htm


2) i've noticed that the newer trucks, silverado tundra etc. have much larger cabs and are much taller than the squares.  So if a square was to get an LS it should produce wonderful mpg?
Swapping an LS into mine did not help the mpg

Felt like it Doubled the power of an old worn out engine though
An LS with a NV-3500 5 speed manual Trans is a real blast to drive
Even with 35" tires and 3.73 gears


We could never determine what engine we took out
305/327/350 ?
No casting numbers on it at all
Either a crate motor or more likely since the truck has a state issued VIN and no factory numbers on the frame or dash. It was a stolen recovery that had every number ground off at the chop  shop

My LS swapped twin turbo truck gets 17mpg on the highway (with me not driving conservative, think PowerTour)  It gets about 13-14 city, again, I drive it aggressively some times.

I don't worry about mpg on any of my vehicles

You lose way way more money on depreciation than the fuel cost
 And since I almost allways get my vehicles for half price I figure I saved enough on the purchase price to pay for the fuel , even if it's 10 mpg

And square bodies are old enough that there is no depreciation , so worries there
I haven't noticed it with the pickups.  But the K-5 Blazers are rapidly gaining in value
