To use a wideband with a regular Autometer gauge or something...

BTW i just got my techedge 1.5 wideband yesterday! It looks pretty complicated but i've been reading up on it. It says u can input a COIL signal, i was wondering if i wired it to the negative of the coil it would work? U know, the same thing like a tachometer or something

Also what i was thinking, the 1.5 wideband unit has a seperate narrow band out put to mimmick a narrow band to hook up to the ecu, this way u can remove the stock o2 and use just the wideband, couldnt i just hook up a autometer gauge to this and it would work?

The more popular of the WB units out there come with simulated narrowband output already..

I see, well i see how people try to scale down the 0-5 volts into 0-1 volts so they can use a AF Autometer sensor, u think it would work if i wired it to the simulated narrow band?

That's what I do..

When my WBO2 display said 14.3, my Autometer is dead straight up center... Seems to work really well without the extra circut.

Holy batman! I should really look into that.. Do u have any info at all about the techedge 1.5? I dont have the display for it and i dont know if should put up the money to buy one. U think its possible to rely on it when its solely connected to a autometer af gauge in the narrow band part?

I wouldn't rely soley on the narrowband.

not sure how a red x will make it work

TurboEF9,

What wideband do you have? I have a plx and I've heard you can use the NB output to datalog when turboedit and uberdata support it. Well I have an Apexi Auto Timer that monitors o2 sensor voltage and i still have it hooked up and it monitors the NB ouput and when I watch it, its no more precise than a regular NB sensor output. It still only reads the same range and when it gets richer than 13.5 or so it just reads .89-.9 volts. How cold this possibly be used to datalog. I really wanna know how this can be used and I'm not try to argue. I just don't understand.

Because TurboEDIT and Uberdata will not be using the narrowband, we'll be using the wideband output (0-5v) connected to where the narrowband input is.

The ECU doesn't know how to use wideband. Once the code is rewritten, and the ECU can understand 0-5v instead of just the 0-1, then accurate A/F ratio logging can be done.

Thats I've been trying to get that answer and nobody seemed to have it. I couldn't see how the NB output could work. When do you think that code will be ready?

I have no idea.. PGMFI (I think) has been working to fix all of the little quarks in the ROM that have been found before continuing to move forward with new features.
