i have a d16z6 head and a d16y8 bottom and p28ecu w/ conversion harness for my obd2 car

my problem is:
my car only boost at 4-5 psi and i get cel in 3rd gear when boostin for a couple of seconds. isnt the stock map sensor suppose to handle 11psi? i even have a missing link. this is really confusing so pls help me guys

oh boy...stock ecu? Plus, sounds like the missing link (which you should toss unless youre running an fmu) is in backwards

stock ecu but already ordered a chipped ecu. i have a fmu also. just wondering if ill still have this problem with the chipped ecu?
and why am i getting a cel when im boosting 5psi i thought stock map sensor can handle 11psi?

stock map sensor read can read up to 11 psi. Stock ECU WILL NOT READ BOOST. Your CEL is most likely happening because you have installed your missing link incorrectly. Just like ghettoturbo has already told you.

so you have an fmu or youre using and fmu? if youre on a stock ecu do not hit boost, especially with the missing link installed correctly. then youll be putting 5psi of boost into a motor who isnt correcting for positive pressure AT ALL

You like talking to walls, Jon.

yeah i know he just never mentioned it at first and then said that he "had" one. i was asking at first if he was using it now or was planning on using it soon till his chipped ecu got there. the way i read it i thought he just had a stock ecu and missing link , sorry

i have the fmu and missing link in the car now but wondering why the cel? ill check the missing link if i installed it correctly
