accent x3 turbo problem
im having a problem with my turboed accent.
i know what those engine can handle don't worry about it lol
my car & setup
1.5L sohc stock
302 500 km ( yes , original but anyway... )
CXRacing t28 10 psi
GlowShift boost gauge
GlowShift oil pressure
custom made vaccum manifold
OBX fmu 8:1
tiburon 2.0L injector
NGK sparkplug ( dont remember model but 1 step colder , gapped to .30 )
all the rest is stock
i checked about 20 time , no boost/vac leak at all.
the problem is when the boost come around 4-5 psi ( it always depend ) the AFR go really lean ( show 20:1 ). the engine rpm stop going up.
if i hold it , SOMETIME the afr show 20 then 16 then back to 20 ( a 5 second WOT run )
for info , my fuel pressure hit 70+ so the fmu is doing its job ( without fmu = 45 )
also my stock fuel pump is in really good shap and hold up the pressure.
i tried unplugging the following but nothing change
even 4 tuning shop have no idea what is wrong.
i dont think its fuel cut because fuel cut is agressive and its not the case.
im lost... anyone have an idea ??? thanks
seem to be MAF related ( bein maxed out so the ecu cut fuel ).
what you think ?
if you think tis the problem , how i fix it ?
i know i could get a bigger maf but i stay with hyundai parts and used hyundai part are hard to find here.
maf clamp sound to be a better solution if its the problem... is it hard to make ?
