I heard that if the a kit does not have the map bypass valve too much air will flow to the cenor causing a cel. Any place that sells the map bypass? Any installation help tip too.

u can use check valves or a missing link

but just get a proper tune the stock map can read up to 10PSI

i plan on getting crome chipped in or hondata so would i need a missing link or would it be fine with a ems in?

Boostdc4

if ur getting it chiped no u dont need it

Chee_dog

so when i go tune, they'll fix the cel code when it pops up? Right now if there is no missing link so cel pops on when in it transit into boost.

there won't be a cel when you tune.

The valves your wanting are called check valves. Any auto store or pet store with fish tanks and supplies sells them but I've found that taking the check valves from geo storm gsi brake booster vacuum lines and replacing the plastic housing with a metal one from the local pet store. The geo storms check valve is located inside the line, so just carefully cut it open till you find it. Have to run 3-4 for 15 lbs of boost but I'm sure it varies with turbo cfm output. Easiest way it to just go to local auto shop and buy em'

so basically all we're doing is just slowing down vaccum to the map so it doesn't pop cel. Anyone have a write up on how to do this i'm new to this. What i don't get is that i'm only running 5 lbs of boost and it stills the map cel pops up. Any less ghetto way instead of running 3-4 check valves?

You do NOT need check valves if you are having the car tuned with Hondata/Neptune/Crome, etc. The stock Honda map sensor can read boost.

i say u get that CEL fixed cause at 5psi you shouldn't need a missing link/hack.
