I got somewhat of a deal on eBay for a never used Candoopro. Seller bought and never used, never hooked it up to anything.
I ended up paying 390+ tax shipped, so I saved about $50-$60. It was the model that came with both diagnostic cables.
Used it today for the first time. I have a bad atmospheric pressure reading. It almost appears that one of my intake boots is coming apart. I ordered a used boot and pressure sensor. Hopefully that is a step closer.
