Thanks Howard, but I called for Steve (that number was correct), and he no longer works for DEK. Don't know if he left, or was laid-off. I know DEK laid-off a bunch of their feild service guys not too long ago...bummer. Also used an inspection mirror and looked for a second set-screw down inside the hole where there was the bolt that I thought was holding the cage to the shaft, and didn't see anything. This has really got me baffled... BTW, the ECU does make a difference here in "Okra-homie"...been up to 90-degrees here so far this year, and we hold about 60% humidity. The real test will be later on this summer when we start hitting 105... -Steve Gregory- > Steve, > > I don't personally know anything about the ECU, but when we had our annual > maintenance done on our Infinity, I asked the DEK FSE, Steve Cox, about > the performance and benefits of the ECU and he said if I get one don't call > him to install it - they are a real pain in the a__!
