Would the settings be saved if the battery is disconnected? I did not see a battery on the circuit board that might be used for that purpose.

 

I wonder if it is any good?

 

It's good to know this is a product that exists, thanks for sharing. Hopefully we can get some reviews from members that try it.

 

Not true, that would require a pot for all the ranges. I would have to see the board up close to see how this one works.
You dont need a battery on board to save data anymore, thats old technology. Its all done with nvram, ferro ram etc. Data retention is supposed to be good for a ridiculous amount of time.

 

The 5 black things at the top are tactile switches, yes. The blue box at the bottom is the potentiometer which according to the instructions is used to adjust all ranges. Select the range, adjust the pot until gauge reads correct than save the setting. Repeat for all ranges. So its not manual but not a "computer program" either. Its just saving values for each range. It just adds or pulls resistance from whatever the sending unit is reading at a certain range.
Its impossible to know exactly how it works without seeing a schematic or at least knowing what chip is on board.

 

I think the meter match has only four set points & this one has five. That should make it more accurate. Very interesting! About a third the price of a meter match.

 

look great!, good find!

 

Electronic parts can be put together cheaply, but $33 is almost too cheap. This is one heck of a deal if the quality is good and it will hold up for years. We definitely need some reviews.

 

I think I'm going to do the same thing. At that price, you can't go wrong.

 

If it works as advertised, a whole lot of members will be forking over the $33 to get this.

 

If it "pulls resistance" from the sender.... I'd like to see that! MOPAR uses 73 empty 10 ohm full on a non linear scale due to tank shape. DOLPHIN is a known by tanks Inc.

Universal Fuel Sender Questions and Troubleshooting

As a manufacturer and uses

• Dolphin - 0-90 Ohms

Perhaps it doesn't pull resistance at all but allows you to adjust to meet what the mopar sender would show within the range of a GM 0-90 ohm sender. MOPAR tanks were always bottom biased when it came to capacity so the top 1/2 of the tank in height was only a few gallons.

 

I assume this one works like the Meter Match I used on my car. The sender resistance doesn’t matter within reason. When you fill the tank to empty, 1/4, 3/4, and full, you push a button on the meter match to adjust till the gauge reads right at each level. This creates a map of the sender resistance to the fuel gauge position. It looks like this one uses an adjustable resistor for the same function.

Instead of filling the gas tank to different levels, I made a test box that simulated the aftermarket sender resistance at different levels (lazy, don’t like to siphon gas).

This device has to have constant voltage (solid state IVR) supply to work. it won’t work with the stock “flasher” type IVR.

When I bought my Meter Match, they sold two types, one with the IVR supply built in, and one that used the IVR in the car to power the gauge. This one looks like it uses the car IVR.

Interestingly, one of these could be used to do the same thing on a temp or oil gauge.

The simulator box is available for loan if anyone wants it.

 

Ford and AMC used the same 73-10 range up to a certain year per that website
