MPGuino FS, Meelis unit, lower price
 

For sale is an MPGuino with a blue screen that I bought from Meelis11. My ebay listing is here: Mpguino Fuel Economy Guage OBD1 MPG Instrumentation Ecomodder | eBay

Your auction states that you cannot use this unit any more. Is it because you cannot find a VSS signal on your Camaro?

No, the VSS was usable, I simply got an OBD2 car and sold my OBD1 car. I dont need it anymore.

Why dont you use it with your OBD2 car?
I have OBD2 car with factory computer and I am still using mpguino :) It gives much more info and mpguino is accurate for measuring fuel economy. Factory computer is too optimistic.

edit: seems that you use ScanGauge now. Anyway - if you want to fool some sensors then mpguino is better for testing - it measures fuel use, not try to calculate it using sensor reading. ScanGauge can give you false readings if you manipulate/fool sensors (or sensor is just defective and gives false info) that it uses for mpg calcualtions.
