I'm interested in an aftermarket wideband o2 sensor, something with a small digital output screen that I can install into my dash somewhere. Has anyone got experience and would like to point me in the right direction? -A
I use 2: My primary setup is a TechEdge 2CO. http://www.wbo2.com/2c0/default.htm I have this with long flyleads and a cigarette lighter plug for easy plug in and I made a stainless "tailpipe" sniffer for portability. The controller and display are separate and there are various methods of connections with both serial, wide band analogue and simulated narrowband outputs to interface with most closed loop enabled programmeable ECU's. Also has an external input (speed/tach/temp/whatever) and basic datalogging capability. Premium quality clobber and carries a premium price of around 500 clams and suits the avid tinkerer. I also use an AEM WBo2: http://www.aemelectronics.com/wideband-air-fuel-systems-15/digital-wideband-air-fuel-gauge-25/ Its a generic round dash guage with a combined analog and digital display. Has a serial WB output but you have to cut up a serial (RS232) cable and manually connect it and a couple of selectable outputs to interface with different programmeable ecus. No datalogging ability which is a bit of a bummer but easily gotten around using Hyperterminal if thats your speed! Bay all accounts a very good thing for the price and easy to install and read. Can be had sub 200 clams on Egay. One note to anybody considering using/fitting WBo2 uego's. These useful things can be very addictive and attention grabbing gadgets to have in the car and youll tend to devote as much time and attention to them as you would when texting on your smartphone. This is indisputable!!!! My advice is to make the guage fitting temporary in the early days and mount them smack bang in the middle and on top of the dashpod with a temporary bracket that tucks into the pod/cover gap, right in front of your eyes, until the initial novelty wears off. I can almost guarantee many "whites of the eyes"....... moments!!! Think Im joking? Ask anyone with at least some interest in tuning who has fitted one down in the center console or well out of direct sight................ See, unlike those beautifully straight AFR charts plotted by Dynodynamics software done during ideal condition power pulls, ACTUAL afr's fluctuate (apparently) quite wildly under normal driving conditions! It takes a little while to be able to interpret the information the guage will give you and youll spend lots of time frigging with the throttle and watching the digital readout which will NEVER settle on one reading.......... trust me on this!!!!!! I have run off the road several times devoting too much attention to my guaes which I have mounted right in my eyesight............. best bet, unless you have a friend who can either drive or interpret, is to log the output of your guage against a specific pattern of driving and then pull over and look at your logged results and compare against previous runs. Just saying is all!! E
I agree datalogging is the only way. AEM has the new fail safe gauge that also has a map sensor built in so can display boost and afr. You can datalog boost, afr, and also has rpm input. Can also set an alarm for certain conditions, boost vs afr. Has boost and afr analog outputs to connect to ecu's. Can be had for $290 delivered on eBay I'm getting one to go with my innovative on the other bank. I think a d/a converter would be needed to get it working in nistune though.
Yes they fluctuate quite madly on normal driving . obviously whats important is what it does on acceleration . I like watching my 8 guages as I'm driving I'm running Haltech Pro ECU with the Haltech Dual Wide Band and a VEI Dual Guage
Which AEM are you guys using, I know the older ones connect. Does the 30-4900 connect okay? http://m.summitracing.com/parts/avm-30-4900
Not sure, though it does say it has USB connectivity. May need Nistune to make some special drivers for that one...
