Here in vancouver BC no one carries teh missing link and has information on this perticular item.
From what ive heard it is a check valve replacement used to fool the cpu up to 12psi.

i went to nrg-racing.com to buy one but i saw two different types.
here is my question...is one better then another or are they jsut for two differnt models? They had them for sale but no other info on them.
I use a 94 b18b...could some tell me or post a pic of what the best type is or what i should get.

sorry to some this probabyl sounds stupid but no where here knows about this. everyone reprograms their cpu or i get,"i heard of it but i never used it before."
thanks

 

i went to nrg-racing.com and i didn't see anything about missing links??

anyways there are generally two models:
1) 92-00 Civic, 94-00 Integra, 94-00 Accord, 97-00 Prelude
2) 88-91 Civic/CRX, 88-93 Integra/Accord, 88-96 Prelude

Hope this answers your question
