A year ago or so, I installed DR's UD pulleys. I like the results, but of course, the idle speed of the engine was lowered a little bit. That's not a problem, except when idling in hot weather with the AC running. The compressor needs a couple of hundred more RPM's to work properly and blow cold air at idle.
This has been discussed before, and it's a known phenomenon. I went through last summer with this situation, but I have decided to do something about it this summer. As you may know, summer lasts from early April to early November in Houston!
To me, the best way to increase the idle would be some sort of computer reflash, since everything is controlled electronically. In the old days, I would have just turned an idle screw on a carbuerator, but I am very hesitant to do that on such an electronically sensitive modern engine.
OK, here's the problem:
I have spoken to several local wrenches, including a Ford speed shop. The speed shop said to just adjust the idle mechanically by turning the screw. I'm still afraid to do it that way.
A couple of others said that the idle can't be adjusted through the computer.
What's the story? How have others who have UD pulleys handled this?
Also, if I can get a computer reflash, will that mess up the aftermarket chip that I have?
