wideband questions

[steviek]

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?

[steviek]

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

[cantgo2fast]

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

[steviek]

what wideband are you using?

[cantgo2fast]

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

[cantgo2fast]

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.

[cantgo2fast]

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

[kjewer1]

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.

[cantgo2fast]

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

[kjewer1]

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.
