Our PCB reads resistance from the fuel sending unit and converts that to needle movement. If your sender – or the wiring going to our PCB – is faulty, the needle is reacting to their mixed signals.

Can I take my tachometer signal directly from the coil?
Yes. We can use a signal from your coil or from your ECU – we just need to know how many pulses per revolution, so it can be programmed properly.

If my tach signal is only 4 volts, will it work with your tachometer?
If your tach signal is less than 5 volts it will require a pull up resistor to read properly.

What kind of sending unit do I need for my speedometer?
We can work with any brand of sending unit if it does not generate more than 32,000 pulses per mile.

How accurate are your speedometers and can it be adjusted if I change tire sizes?
Our PCB counts up to 32,000 pulses per mile – or approximately one pulse for every 6” you travel which provides highly accurate readings. Adjusting the speed takes only a few minutes using the thumb drive and a PC.

How does the PCB connect to my car?
It takes power from your vehicle electrical system and input signals from the sender for each of the gauge functions. Connections are made with color coded wires coming from harnesses that plug into the PCB.

What is the PCB?
It is the electronic brain in our system. It takes input as electronic signals from the function senders, interprets them and then sends signals to the stepper motors driving the needles to make them move appropriately.

How do I set the time on my clock?
If you touch the silver button at the six o’clock position on the clock the hands will start moving. The longer you hold the button the faster the hands move. When you remove your finger the clock hands stop moving.

I just installed my new CON2R gauges. Why is my tach needle movement erratic?
If the needle movement on your tachometer isn’t smooth, you likely need to install a tach filter. Tach filter installation instructions can be found here.
