I bought this to help tune my R4 controlling software. To get my base line line setup like in Gadgets U-Tune pdf. I recently got a ultra gauge as a gift and do need this anymore. New these are $87 + shipping. I'm selling it for $70obo shipped in the USA. There's nothing wrong with the unit. Works great just need to sell it. Plugs into either your serial port or a USB to serial cable. PM me if your interested.
