I am about to add my turbo set up and im minus a Wideband. I plan on reaching 280hp Stock internals at 8-10psi. Is it essential for me to have a wideband o2? Can I get away without one for a while. Im getting the car dyno tuned after I turbo but how long will that last?

just get one,

better to be safe then sorry.

it's cheaper to buy a wideband then to replace engine parts cause your too lean/rich.

exactly.

i just bought a Innovate Motorsports Complete LM1 setup tonight brand new for 200 bucks shipped from a dude off zilvia. retails for 350.

just search around you can sometimes find good prices on widebands, and for a complete kit 200 shipped is a steal.

It tells you your live AFR's. I just bought one for my car. I bought a AEM Uego. Now when I get on it, I ALWAYS watch the gauge.

well i should have said: whats the real purpose.. I know it displays that stuff, but is it just so you can monitor AFR so it doesnt lean out or run too rich ?

Nobody has answered my question. I plan on getting one later on but after I turbo ima be flat broke. After i install the turbo im going to get it dyno tuned. How essential is it to have the wideband immediately. What if I wait a month?

why don't you wait till you have it.

i'm not sure how good of a "Tune" your gonna get put on your car without knowing your AFR.

seriously how much have you spent doing your turbo build up? whats another $200-300.

to the person asking how do you fix if your too rich or too lean, you get a fuel controller (apexi SAFC, or others) search around.

::IMPORTANT::

If you install a turbo and your motor blows, you won't know why.

If you have a wideband you'll at least know you aren't running lean, so that you can PREVENT blowing your motor.

if you get it dyno tuned wouldnt you have the AFRs from the dyno ?so hopefully it should be decently safe for a short period of time?

theorectically it should be fine. But its recommended to have a wideband so you can monitor what your motor is doing and essentially keep it from blowing up. whats another $200+ rather than spending alot more money for a new motor???

correct, if you get a tune on a dyno they all use some sort of wideband o2. whether it be a sniffer wideband, or if they put a direct one in your o2 bung. either way theyre both very very accurate. essentially, once tuned safely you should be ok without one.

however, i would go ahead and get one anyways. my first ka-t i never ran one. i street tuned it with an safc, and a borrowed wideband. once it was all tuned to my satisfactory, i took the wideband out and gave it back to my friend. the car is still running to this day on a motor that i built from the ground up (all new internals). this was done 4-5 years ago. the guy who bought the car flew from texas, and drove it there non stop from here in orlando, fl (LOL without a tag mind you that, and never got stopped).

my last ka-t i bought a aem uego, and had it permanently mounted. main reason is because i was a FMU on stock motor. that car is still up until about a month ago when it was stolen and stripped ( this car was running awesome for exactly one year).

get one as soon as possible though. piece of mind. gl with your dyno day.
