Boost but No CEL, No missing link, stock ecu?
 

hi,
today i drove my civic d16Z2 to testrun it, it was supposed to go till the Ceck Engine Light @ 0 psi ?

i have an FMU, but no missing link. (on purpose to hit the CEL) i m going to chip the ecu next wednesday. but i thought with an fmu, and no missinglink, there wont be boost.
but at first i got 3 psi, and then 4,5
so i stopped!
my a/f gauge was in rich, but ofcourse i couldnt see how rich...

how can i have boost?

Re: Boost but No CEL, No missing link, stock ecu?
 

b/c your turbo is spooling that creates boost but why your ecu dosent read it and ---- itself is another story

Re: Boost but No CEL, No missing link, stock ecu?
 

i know the turbo is spooling, and that was what i was testing tillt 0 psi, but i assumed there would be a CEL,
i also assume that i have a stock ecu.

but why doesnt the ecu show a CEL?

Re: Boost but No CEL, No missing link, stock ecu?
 

Hit 11psi. It'll come on.

Re: Boost but No CEL, No missing link, stock ecu?
 

no i will destroy my engine...

there must be an explanation for the cel nog lighting up !?

Re: Boost but No CEL, No missing link, stock ecu?
 

it has to see the boost for like 5 seconds or more, and usualy dosent through till second








p.s. i'm running 11psi on a fmu :y

Re: Boost but No CEL, No missing link, stock ecu?
 

really? 11psi stock internals?

what kind of fuel lines you have? from your fmu to the fuel rail? im affraid mine wil explode like an egg in a 1200 watts microwave

but the ecu needs to see it for a few sec? hmm ok. that will explain all.
do you have an 12:1 FMU? and whats your a/f ratio ? at differnt boost pressures
i only have a narrowband lambdasensor hooked to an a/f gauge, so its not accurate

Re: Boost but No CEL, No missing link, stock ecu?
 

10psi is an HMT minimum. Anything less than that is like buying an air/fuel gauge for a narrow band.

i got a z6 with eagle rods and spr pistons. but i was running the same boost on my mini me with 10.5 compression for 1.5 years with no problems

just stock fuel hoses. they wont blow i've never had that happen ever.

Re: Boost but No CEL, No missing link, stock ecu?
 

man 11 psi with an FMU is crazy man.. stop messing around


im going for 10 psi. have it chipped and dyno run it.
but dayly drive it on 5 psi
but i stil have a stock clutch, so i dont know if it wil hold ahhaha. i guess ill replace it for anotherone till its wasted (6puck or whatever)
