wide band this.....wide band that......?

What is a wide band, and why do i want one?

It sounds like all your tuning problems can be solved with the presents of this wonderful item. However I can't seem to find information on exactly what it is, what id does, where it goes, .....etc.

sorry for my ignorance

thanks for your help

its a sensor/controller combo used to monitor/log your air/fuel ratio. its better than the stock narrowband sensors because it covers a greater range of ratios (usually from 10-21) instead of just right around stoich. they come with a wideband oxygen sensor that you add before the cat.

its just a monitoring device, you still need fuel management (safc/retune/emanage) to tune with. but it makes it much easier being able to datalog on your own and stuff.

with the boost sensor, EGT sensor, and lcd screen, you have all of the guages, and you wouldnt need other guages...thats like a 400 dollar savings, WOW! /end advertisement...

it comes with everything but the lcd display screen for $279. can you just use a laptop to display the data? i really dont want to pay over $100 more for the display screen.

the boost and egt sensors arent included for the 279 either, but yes, you can output the data to a laptop with a real time display or datalog plot. it also has a wideband analog output you could send to a properly calibrated gauge.

and the resolution is higher too. a narrowband reads lean from 0v to about .2v, stoich from there until about .8v and the remaining .20v (0-1v resolution, mostly in the stoichometric range) while a wideband reads a linear, for the most part, 0-5 volts (I think the new bosch/vw's everyone uses now may only read to 3.2v).

I think some of the best info I have read on widebands/tuning is here.
