I'm finally getting around to hooking up my AEM wideband to be able to datalog my A/F ratio with my Xcal2/Laptop.
A few questions:
I cut the female end of the 9 pin connector I got from SCT.
Using a multimeter to figure out which wires are analog 1, analog 2, and ground.
From the back of the AEM wideband I took the red wire and hooked it to a power source, black I grounded.
Now I have a white wire and a blue wire left coming off the wideband.
Are both needed?
Or do I only hook up one to be able to record my data.
In other words, do I just need to hook up just Analog 1 from the Pin connector to say the blue wire? or do I hook both up? Also do I need to ground out the 9 pin connector wire that is coming from the xcal2?
I found this picture along with a few "how to's" but none were very clear....
Also I've been getting different responses for the formula used to datalog as well.
Is this the one you use?
V*2+10
Thanks.
