wideband questions

so im thinking about getting this wideband with the two outputs will it go to a gauge and to the ecu so i can log it with dsmlink?

Whether or not it works with a display depends on what they offer. I would check the main Innovative site and see what they have. I would assume that this is what the digital output (probably serial) is for. The LC1 does work with DSMlink, IIRC, you log it as the Techedge WBLinear.

would i have to plug the output from the wideband into the laptop directly or can i log it through the ecu just using the obd port cuz i really dont need anymore cables in my car lol

You can log it through the ECU, is this is by far the recomended method. This way the WBO2 trace shows right up with all your other data and lays over it, to scale. Works the balls.

You'll end up wiring it into the rear O2 sensor input at the ECU most likely. You can also use the MDP sensor input, but I believe I usually put the MAP sensor on that now.

will it just plug in or do i have to create some wiring

It's not like Mitsu anticipated the developement of DSMlink and use of WBO2s, you'll be doing some wiring. ;) The good news though is that it is only one wire. If you are like me and don't like permanent changes, you can just splice/tee it in rather than chop up the harness, as long as you don't plug the rear O2 into the connector of course. You can get the pin/wire location from the vfaq's 2g ECU pinout diagram.

Hey I really want to stream My AEM EUEGO WB02 ratio into my rear 02 inlet for the ecu so I can log it. However I don't know which wires to solder up to it. Does anyone know?

Run the analog output of the WBO2 to Pinout #75 (http://www.vfaq.com/mods/ecu-harness-2G.html)

thanks then how do you set it up with dsmlink so it gives you A/F ratios?

you have to find it under the captured values and make the ecu capture it then under values(f4) pull it over so it displays with all the other stuff

well I get the readings off my wbo2 from rearo2 but Im getting it in RAWvoltage only how can I get it so it shows a ratio:1 ?????

It has a specific name check under AEMuego (or something close to that)instead of rear02 under captured values

Probably AEMguage (or similar) since you have the guage type. There are 3 IIRC, and they are all different.

Ahh yes it is so simple now! Works perfectly thanks.

where did u solder your 12v switched power supply into?

for the wideband?
I spliced it off the backlight for my boost gauge. Which is wired straight up to positive and negative terminals on the ecu.
It was an easy target because when I took off my afc it was right there and exposed so I was like perfect unsolder one wire resolder a new one

that sounds like a good idea thanks

I've always taken power for miscellaneous interior gadgets from the cigarette lighter circuit. It's easy to tap into, already fused for 10 amps, etc. As long as you don't actually use the cigarette lighter of course...

a good idea as well i have so much stuff to do this weekend i dont know if ill get around to the wideband especially now that i smashed my windshield and have to get that fixed. I also have to install and areomotive FPR try to fix my idle etc etc

well as it turn out the wideband came early so i put it in today. i got everything soldered up and installed but my gauge hooked up to the analog output is reading 8.6 at idle while my narrowband on my turbo timer reads 14.7 what could be the problem. could it be my calibration i followed the directions as best i could could it be something else?

wait you have a narrowband and a wideband? Don't trust the narrowband at all. What part is logging the 8.6 is it the dsmlink or the actual gauge. If it is the dsmlink its probably some kind of software error. Like How i chose the wrong wideband input

my wideband controler has two analog outputs a simulated narrowband output which is designed to go with my gauge and a much wider analog output which is spliced into my ecu. But the gauge should still get accurate readings from 9-17 AFR the second analog output is designed for readings from 7.5-22.5 AFR. Yes i still have a narrowband with my TT but theres no way my AFR is 8.6 at idle

what wideband are you using?

Innovate LC-1 wideband controller if you look at the link at the beginning of this thread thats the one im using except i also got their DB gauge with my kit so its all designed to go together

well i just plugged in dsmlink to see what value it was getting and dsmlink was logging 15.4-16 afr at idle while my gauge was still off as well. Maybe i have to program the wideband and set the value its seeing at idle as 14.7 with the logging software? I assumed it would automatically figure out the afr based on the free air calibration

Sounds like the display is set for another type of fuel, probably methanol.

even if im getting two actually three diffferent readings one from my gauge one from my ecu and one from my narrowband?

The WBO2 unit may only be sending the lambda value to the display, and the display has to display it in the desired AFR unit. I can't recall if my techedge unit programs the AFR fuel type in the unit itself or in the display, but both can be programmed with a laptop. Either way, this is something to take up with the manufacturer of the product IMO. ;)

did you have the same wideband as me kevin? if so where did you ground your wires?

If I did I would have handed you all your answers on a silver platter, because that's how I roll. Unfortunately I have been running the Techedge unit for the last 4-5 years (www.wbo2.com). I don't know why it's not more popular than it is, depsite being the first supported by DSMlink, it's badass.

My unit is grounded to some bolts under the center console, since I have it mounted under my passenger seat.

Thats where i grounded mine too i thought my weird readings might be from grounding problems but if ours our grounded to the same place so i guess ill start looking for problems in the wiring itself. And after i recalibrated the unit i still got weird readings from the display and dsmink but the AF meter on my turbo timer was working perfectly like a wideband so i think ill start seeing where that goes and try to hook my gauge up to that instead. If i spliced my analog output into the rear o2 pin on my ecu do i have to cut it cuz right now its just sitting there with the whole thing still attached

|I cut mine

well i cut mine too but right after the sensor so i dont think it should be getting any voltage. but i guess it couldnt hurt to cut it closer to the ecu. ill just have to experiment

well as i turns out a towo afternoons spent with the soldering iron, wire cutters and a voltemeter and i finally figured everything out works great thanks for the help you guys. Im about to start another thread lol this time for my FPR
