I am just copying and pasting a question from CarlC on PT.com. Thought some of the info may interest you guys.

Carl, This unit has two very small potentiometers on it and you set "full" and "empty" by adjusting them so your gauge reads correctly. Do to all the different sending units and the fact that different gauge manufactures seem to use a different voltages to determine full and empty this was the only way we could build a completely universal product. The nice thing about this product is you can calibrate any ohm range sending unit to work with any ohm range gauge. I guess I shouldn't say any. As long as low resistance equal empty and high resistance equals full on both the sending unit and the gauge, the module works perfectly. Vise verse, if high resistance equals empty and low resistance equal full on both the sending unit and the gauge, this module will again work properly. ie A 0 ohms empty 90 ohms full sending unit using a 10 ohms empty 30 ohms full gauge or a 240 ohms empty 33 ohms full sending unit using a 75 ohms empty 10 ohms full gauge.
I've got a new 69 Camaro project in the works that I already have a VaporWorx set up for. I will be testing these two products together with my SpeedHut gauges once my project is a little further away. We do plan to do some bench testing with the two products together before my car is driveable. If you would like info on the results just let me know.
I should also note that we haven't set final retail pricing yet, but we are hoping to be about to sell this Module for $35-45. Wholesale pricing will be available also.
Thanks
