The directions say that it will take 5-7 days for the ECU to adjust to the lighter pulley. 1st impressions are both good and bad. First off, the car fly's through the rpm's much faster, thus giving a feeling of faster acceleration. Second and the bad, you couldn't tell my 2k2 Auto was running while stationary and after the UDP was installed there is a slight jiggle when stationary. Doesn't matter if it's in drive, park or neutral. It's a tad more jiggly when the heater and A/C are on. Is this normal? Will the ECU correct this? What could be the problem?

 

Are you sure the jiggle wasn't there before?? better make sure your harmonic balancer is installed on the pulley.

 

and double check that the flux capacitor is working properly lol

 

I believe it was SR20DEN who posted that he had the idle speed raised to 625RPM to handle the @ idle requirements of the AC/etc.

 

I gave the shop the directions and told them to follow them explicitely. I don't believe the directions said anything about the harmonic balancer on a 2k2. Just said to make absolutely sure to put anti-seize compound and make sure the sleeve is reinstalled. I've never noticed the jiggle before, but I am quite **** and notice everything if I don't do it myself.

 

haha the flux capacitor, youve been watching too muc of the DOC !!

 

Life sucks when you're like that! I suffer from the same "No one can do it right" syndrome!

 

Horrible disease!

"No I don't know how to do it, but you did it wrong"

 

Which underdrive pulley is it? Unorthodox's does NOT have a harmonic damper ~ which is why there is so much debate about them over on 3Si.

 

we don't have harmonic balancer's on our pullies anymore.

Its proabaly due to a lower idle.

 

After installation of the UDP on my Max, I detected no additional jiggle. I, however, have a 2K1 Manual and my flux capacitor is in perfect working order.
