Think i found a way to scale down Wideband range
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?

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?

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?

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.

Re:Think i found a way to scale down Wideband range
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.
