I've been reading up on the VX o2 wideband sensor and have a few ?'s. I would need some stuff from techedge to use this of course, but do you need a stand alone system to make it worth while? Could I do anything with it if I have a factory ecu and vfac or will I need a datalogger of some kind? How would this be benificial to own as opposed to dyno tuning?

standalone is good if it can read the wideband and use the info to autotune. u don't need techedge and u don't need a standalone to make it worthwhile.

yeah u could use it to read your a/f ratio correctly and accurately. then, use the vafc to lean or richen the mix during specific points on the curve to obtain the desired a/f ratio. u don't need a datalogger but it's very nice to have records.

u don't need to use their wideband.

 

thanks. so if I got the honda vx wideband sensor I would have to get the techedge wideband unit to use the sensor with my factory ecu? or would I just need the cable or what?

What do I need to make it work with my factory ecu and what kind of a/f meter would I need?

unless u are using an hx or vx ecu not gonna happen with oem honda ecu. the techedge type units are used to read the sensor. as far as reprogramming the prom to do such is another can of worms. (don't even know if possible)

it's just another tuning tool that provides useful information like an EGT. EGT won't work with your ecu. same wit wideband. u have the information from it and u tune accordingly.

a/f meter for a wideband output of lambda or read the voltage and interpret manually or one that can read the voltage and conver it to a/f ratio.

 

you dont have to worry bout ecu just tapanother 02 bung on as far as i know you do need the techedge or someother interpretter to find out the info from sensor

They have what you are looking for,

with the techedge unit, you dont have to tap another o2 bung. you will eliminate your narrow band sensor and but the vx sensor in its place. the hook the vx sensor up to the techedge. the techedge offers a narrow band output, which you will route to your ecu for its readings. also, you will hook up either the techedge display to the techegde controller, or hook up a palm pilot/laptop to the techedge controller so that you can see and/or datalog your readings. its pretty well explained on the techedge site if you take the time to read it all. i have this setup right now and it works great. its nice not to have to weld another bung on. the palm datalogging works very nicely as well.

 

I only said weld a new bung so that he wouldnt have to **** with the stock ecu

i realize that, but personally i think its MUCH less work and money to tap ONE wire than to bring the mani somewhere and weld a new bung on. although there are the people out there that are great welders but suck at electronics...so whatever floats your boat i guess.

 

Well the whole idea of it is not messing with the voltage to the ECU, it would be nice to have a whole another bung tapped and never have to worry about your A/F Gauge mess with your real o2 readings.

 

Techedge + VAFC

 

Damn that is nice, do you have any data logging or do you just look at your RPMs and adjust accordingly. 100Mph at 2800 RPM I'm guessing you don't have the S1 Trans.

 

i don't have any data logging, i just look and adjust.
First i adjust FPR, than lean out with vafc.
That was a LS Tranny, LS/VTEC. now i have s80 lsd tranny.

 

Do you mind telling us how much the whole wideband setup cost you, "too much" is a fine answer too if you choose.

 

wide band o2 sensor around $150 USD from thepartsbin.com (before now is $320)
the unit around $100-200 USD (parts only)

i don't think i can live without it..

 

So do you have an extra bung for that, and if so where about did you put it?

 

i personally have an aem that runs in conjunction with the techedge 1.5(320$) and a bosch 5 wire(180) dont know how it works yet im finishing this weekend

i believe its 100kmh

what all do you have? the te-wb 1.5, cable, and display? do you need all three?

 

i have the 1.0
you need the sensor and the unit. you don't really need the display if you got AEM hondata or something that datalog.
horse's? i don't really know.. i never took it to dyno..
i put the controller in grove box, and sensor on testpipe (where 2nd stock O2 sensor is).

 

id buy all 3 parts its only 320
