what is a wideband tuner? can i tune my vafc with it? would it be any different it i tuned my VAFC with a wide band tuner than a dyno? thanks

 

anyone???

 

someone has to know! please

 

i woul;d guess wide band o2 sensor wide band has w wide range to read low and fuel ratios ie wide band lamda meter wide band o2 go hand in hand

 

your stock O2 sensor does NOT read A/F, it only tells ya if it's rich or lean. If your A/F is greater than 14.7:1 then it will read about 1 volt (lean), and if it's less than 14.7:1 then it will read about 0 volts (rich).

A wide band O2 will actually read your A/F so it can be use to tune your car's A/F, were the stock can not.

 

like the person said above, commonly used stock o2 sensors are more of a switch except cars like 92-95 HB Vx...(which came with widebody o2 sensor)

widebody o2 sensor actually puts out different voltage for different a/f ratio so that you could accurately read what a/f ratio u have at the moment. If you have ever seen the fancy light show of an Autometer A/F monitor, you know what I mean...just bounces like crazy...

Go to dynos with a wideband o2 sensor, Most places should have them.

okay, here's the thing. i have a friend that says he doesnt have a dyno, but he has a wideband tuner. i am asking if it will do the same thing as a dyno. i want a VAFC and he said that he has a wideband tuner, and i thought to my self, if it's a wideband TUNER, then maybe it can tune my VAFC. also, how does nit work. and what is a lamba ? thanks

 

wideband and lambda setups read a/f mixture more accurately ... he means if you get a VAFC then he can fine tune your VAFC fuel settings in the street using his wideband tuner (comes wiht o2 sensor as well as display) ... mine comes with logger and I use it to tune VAFC and Programmable engine mangement setups for people in the street.

the dyno is different in that you dont just tune a/f mixture ont he dyno, you can do things such as cam gears, ignition timing maps for those with programmable engine managemnet systems,e tc... in your case on VAFC for dyno and if you have adj cam gears that can be tuned as well.

Also consider that the air around a dyno can be very different from that in the street day-to-dya driving.

thanks. and also, how much hp do cam gears give me on a stock motor?

 

it wont tune your vafc for you it will allow you to tune it better though but pretty expensive if all you have is a vafc take it to a dyno they have a community wideband

 

they help to dial in your power band, anywhere from 8-15hp under the curve and 2-8hp at peak

greg

 

so it WONT tune my VAFC? then what does it tune? it hought soeone said that it only tuned the air/fuel curve.

 

re-read my post ... if your friend is a tuner, he just needs to learn how to use the vafc and adjust it at each RPM ... he can adjust the VAFC (while using the wideband) and while you drive to get the ideal a/f ratio ...

greg

 

it doesnt tune anything its a gives you the af ratio YOU tune off that

 

oh okay. so what does this thing look like and where does it go? is it accurate? thanks

 

depends on which one you get
1st you have a special o2 sensor like 200$
2nd you have a control box under your dash 250$
3rd you have a display of some sort 50-200$

where does it hook-up? sorry about al the questions, this is new to me

 

the o2 sensor is on the exhaust the control unit i believed is wired to the sensor maybe the ecu and the display i dont know exactly where the wires go ill tell you in a month or two

 

DO A SEARCH (TYPE IN WIDEBAND). You'll find 30 times the info that people are going to type out for u.
