I know my buddy Kevin was stating that his fan speed seemed low lately due to the weather and it took him a hot to defrost. He believe it was the ihk unit or the fsr that was going bad. He then plug it to the computer, bump the fan speed and change the key memory. Hopefully that solved his problem. I do have a few more scanners if interested as well. Pm me if interested. There is a for sale thread if you want to see what else you can do.
