I've never used the smc so i cant verify that....maybe you have it wired wrong?

 

nah my wiring should be good cause i was boosting before but only last night it start to not let me boost..

hmmmmmmmmmmm

 

no cel. no boost. engine in good shape?

 

yupp engine still runs strong..

 

check all intercooler piping, vaccuum lines...do you hear the turbo spooling up just no boost?

ahhhh beat me to it! Def check your cuplers on all your piping all of them. From the I/C to the I/M. Thats a must! Good Luck!

check this

 

all the pipes are good...its when it starts boosting it starts to sputters...like misfiring..

 

it could be wayyy rich.

 

spark plug gap?

 

plugs are gap .32 and are nkg 2range colder plugs...

i think i might of hooked up my SMC wrong whats the pinout for the MAP on the ecu...b18 obdo?

 

I had a simular problem a while back. it turned out the fuel pump was going out and it would lean out and the sputtering instead of boosting was detonation.
could be a problem with your fuel system as well..

 

what the base fuel psi? sounds like the same prob with my old honda. check the pcv valve(they tend to build up with carbon!)

Is the turbo working alright? I had a problem like this, what happened was the nut holding the compressor wheel on the shaft had backed off and the wheel was jamned. The motor ran fine, but when right as I should have been building boost it would sputter, not build boost, and blow smoke out the tail pipe.

Also I have had IC pipes come off enough so that I wasn't getting any pressure in the intake manifold, while the turbo was building boost.

What the sentence mean? What is base psi? He said he wasn't building any boost, so why does "base psi" have anything to do with it?

Make sure youre accounting for the extra "bleep" on the SMC. I was dialing %25 out instead of 35%, which was causing exactly the same condition you are describing.
Also, double-check your wiring...Ive had problems with the provided diagrams being WRONG, which will really screw things up.

yea i think i wired the MAP wrong...the diagram they gave is kinda hard to understand...anyone know the MAP pin out on the ecu?
