Hi folks,

a while ago i stumbled on a website for someone that was produced kits that corrected that early model legacy (mine is 1990) flat spot on aceleration. Evidently the knock sensor "hears" a knock when it isnt so it retards the ignition too far. The kit "filters" the noise allowing the knock sensor to funciton properly.

 

Does anyone know of the link to the site? My HardDisk died a while ago and i lost my bookmarks.

 

Does anyone have experience with the particular kit? or any other solutions for this problem?

 

cheers

I've used it.....wasn't really impressed with it. It's just a set of resistors to attenuate the signal.....or at least that's what I remember....

Thanks for that. That was the one i had in mind..... so now i dont know whether to give it a try on mine. Sounds like its not really worth it. Probably better to do things like replace old MAF sensors to improve engine response i guess.

clean maf with brake cleaner....but do be careful. Also, you can get an updated knock sensor. The old ones cracked and gave some false knock readings. They're not too much if I remember.

Also see http://www.ravensblade-impreza.com/modifications/drivetrain/paperclip/paperclip.htmlwhich explains what it is. I tried it; worked ok, but let the engine knock a little more than I liked. A new knock sensor ($62 from 1stsubaruparts.com) fixed it. -- George

hmm....that's definitely a different approach then how the kit I got installed....that or I misunderstood how it was supposed to go together.....
