aem wideband

[elias_799]

just to get something clear, i hook up the white wire (5volt output from wideband) to the #1 pin on my mpvi pro ? i do not need to hook up the ground to it or anything ?

also what numbers do you use to set up the aem wideband, i have seen that the lc widebands are somethink like this

0 volts 10.0 afr
5volts 20.0 afr

so what are the numbers for the aem wideband ?

Start by searching the help that came with the product and/or searching the forums

help file->Working with VCM Scanner->Enhanced IO

The Connecting and Configuration pages should get ya covered. There is an example for connecting a LC1 wideband in the EIO How To Section as well.

You will hook up a ground wire from your wideband to pin 5.
There is a pre-defined input for the AEM, so you dont need to manually calculate the transfer function, but it is:

AFR=Vin*(Vmax-Vmin)/(AFRmax-AFRmin) + AFRmin
AFR=Vin*(5-0)/(20-10) + 10
AFR=Vin*.5+10

From the dead.....

Right now I have the following hooked up:
Red wire to 12v
White wire to EIO Pin 1
Black wire to ground

EIO Pin 5 to ground (different than the AEM ground possibly?)

Is that wrong?

You only need one wire.......

You only need one wire.......

.....please elaborate

On my AEM there are two wires for datalogging, a white (+) and a brown (-). White goes to EIO Pin 1 and brown goes to EIO Pin 5. Even though I've been told you only need one wire I figure if they give you two might as well use em and still use both wires now logging through the EGR pins (white to #55 and brown to #41). Also the numbers I had to use in the scanner was volts/.422 + 7.312

Hope that helps

I have 4 wires:
White- 0-5v output (going to EIO Pin #1)
Black- Chassis Ground (going to a good chassis ground)
Red- 12v power (going to a switched 12v source)
Blue- Serial Output (capped off)

Then on top of this, I have my EIO Pin #5 going to the same ground as the AEM UEGO black chassis ground

Sorry I guess we have different AEM widebands, mine has more than 4 wires.

Mine is the 30-4100 AEM UEGO wideband gauge
