are you by chance running an FMU?

would a stock map seeing 12psi do it?

Re: boost problem check engine light on
 

a stock map seeing any boost would do it if its not a modified rom with tables extending into positive manifold pressure.

but if its chipped and all that, no, it wouldnt.

try using a the Missing Link(check valve) it prevents the ecu from seeing boost in the manifold http://www.synapseengineering.com/pr...ssinglink.html

what is the cel# you are getting?

Re: boost problem check engine light on
 

I dont have a fmu I do have and upgrade ecu is the zdyne gold Im current running the B16A VTEC
Forced Induction
Spark: factory PW0, 1 deg retard / lb
Fuel: factory PW0, recurved for 450s, 166% @10lbs program with the stock map sensor, what Im worry about is the if Im running 12 psi or little big more that will broke my motor .
also I just buy the check valve and i dont know where that goes , can anybody help me by post a pics or diagrama showing where the check valve goes I will apreciate thanks ???

Re: boost problem check engine light on
 

you dont need checkvalves if you're running a zdyne gold

Re: boost problem check engine light on
 

i thought the stock map cant read above 11psi w/o throwing a code

Re: boost problem check engine light on
 

well the check engine light is on so Im not pretty sure to run 13 psi of boost with manual boost control can anyone help me decide what it will be the best think I can do ???
