im throwing a 1 and 3 cel i think its from the vac to boost change over ive heard of using check valves how does that work?

 

One is your o2 sensor, is it tuned?

 

the o2 was from oil now its just map how can i fix that

 

you should ask this in the FI section but if you are running over 11psi I believe then you will throw the code for the map...ideally you should convert to a 2.5 or 3 bar map sensor but you can use a check valve system to bleed off the boost or use one of the missing link things...just do a search on here and you should be able to find info about it...

 

If you are not using any boost code on the ecu then yes the ecu will throw a map cel once its sees like 1.3psi,I bileve.... Yes you can put check valves between the map and vac source, but i recomend going with some real ecu tuning ie hondata, uberdata etc or if you are still obd0 then turbo edit
