Another gauge corrector--cheaper than MeterMatch, 33.00

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.

The problem with all of these when used with the OEM fuel gauge is that the gauge reacts so slowly due to it's design that you have to be really patient and wait for the needle to settle before moving on to the next fuel level. And mine was backwards so full didn't read anything and empty wanted to peg the needle on the wrong end. Which meant each fuel level step typically took a fair amount of pushes to get it going the right direction and sometimes required "catching" the needle before it pegged.

The next trick is to be able to feed the module the correct resistance. But if you have a setup like above, you can pretty much flip the switch, move the gauge around using the plus and minus and let it sit for a minute or two and it should be close. My method of moving a sending unit to match a line I had drawn on it was tedious and potentially less than accurate.

The Fuel Bridge module I bought seems to work pretty good best I can tell once I got it set (took 2 times). It has a test when you start the car where the gauge is supposed to go to full and then back down to the fuel reading, but my gauge is so slow that the test phase is over long before it get's anywhere close to the full mark. And there are times where it seems off, so I don't think it is perfect. But it is better than it was, that's for sure.
