i have a d16y7 turbo, it is running very rich, black smoke coming from the exhaust, i changed the 02 sensor but no luck.
can someone help?

is it dyno tuned?

What is your setup? What kinda of fuel mangment are you running? we need more info to help you.

the car is not dyno tuned. The ecu is running on crome.

You need to get a wide band on it. Its really the best way to tune IMO. Do you have a FPR? What injectors are you running? Are you running an open BOV (venting to atmosphere) did you change out your fuel pump?

yeah i have a fpr, 430cc injectors and a walbro fuel pump. the bov is an open one. how much can i buy a wideband?

depends on what u want and how much u willing to spend? Those are questions u should be asking for a wideband.

i want one that will do the job, but not too pricey. where can i get one from?

Your running on a basemap that is why you are so rich. Get it dyno tuned by someone who knows what they are doing. Then do some research on turbocharged hondas.

Ugh, why do people buy before research...Any half retard knows that a tune is crucial to a turbo'd honda...Sigh[:@]

Get it tuned, my tuner provides the wideband.

better rich than lean lol

get to your tuner asap, hell hook his own wideband up and get you running right... youll feel a HUGE increase in power as well, and gas mileage, so it will definately be worth the $250+ youll spend on a tune.

dont be lazy, and or stupid... your car is running on a kindergarden brain, once your tuner gets through with it you might actually reach high school... get hondata and maybe get your masters... get hondata s300 and a great tuner and youll get a phd smart ecu that actually knows what your car is doing and or needs.

tuning and fuel management is the most CRUCIAL part of the turbo, every turbo noob needs to know that before they even begin, i dont understand how so many people F***that part up lol
