Wideband

[misterjose]

Hey guys
well i got a AEM wideband from a fellow member for a good price.
i know AEM is not the best wideband but it will have to do for now.
i plan on getting link once taxes comes and probably LC wideband.
im about to install the AEM wideband and everything is pretty much plug and play.
however i do have one question, since i don't have link yet do i still have to connect the white wire from the WB to the ecu?
im using mmcd for logging.
thanks =)

No hooking it to the ECU is when you have link and tell the ECU the the pin you jacked is now your wide band and not say your rear o2.

It would be pointless for you to wire it in to the ECU if you plan on getting an LC-1 after you get your tax return. And especially since you don't have link yet.

Just to clarify for myself but we cannot run a wideband in place of the standard narrowband in the 1G because we would need some kind of software such as ECMlink to provide a narrowband simulation correct?

 

[ramsack]

What about gauges/controllers that simulate narrowbands on their own?

 

[snowborder714]

If you had the LC-1, it has a built in narrowband simulation (2 signal outputs, one for 0-5v wideband and one for 0-1v narrowband).

You don't have to But,
You could still log it with MMCD from the EGT input though the scaling isn't right and the AEM White papers are wrong... .

You could try to switch the output on the back of the AEM gauge to simulate a N/b o2
But, IIRC the reaction time is so much faster it won't work correctly...

If you had the LC-1, it has a built in narrowband simulation (2 signal outputs, one for 0-5v wideband and one for 0-1v narrowband).

You can Also change the scalling of either to what ever you would like...

So say you can Log an output for Link, et cetra and also to A DB Gauge

Yep, I'm aware of the ability to reprogram both outputs, but figured it wasn't applicable to the posters question. But either way, it's a very nice feature to have!

I was wondering about that. I was just reading the manuals for Innovate products and they are 1.1v for 14:1 and 0.1v for 15:1, but an actual narrowband has a tangent-like curve. Are the simulated signals linear or, in fact, a curve? I was looking at the MTX-L to be exact, not like it matters, they all seem to operate the same, just different externally.

 

[misterjose]

so all i have to wire up for now is ground and positive right?

 

[snowborder714]

Yep.

ramsack, I'm not sure the answer to your question.
