help logging wideband

[bomrrman84]

i found some write up on it but, im having a really hard time getting the wires right to log through my Xcal3 with my wideband 02 sensor. Amazon is my tuner as well, im going to give them a call in the morning and see if they can help me too. oh by the way im using an innovate lc-1 for my wide band. any help would be appreciated.

connecting sct x3 to a wideband via firewire please help

Thanks for the link!

Not a problem. Used it to wire up my MTXL.

so my question is, i wired everything up originally but apparrently i wired into the digital outputs on the LC-1 not the analog when i went back in to hook up the live wire. i appreciate the link and it is good info but, there is an almost identical one for my specific setup that i found using the search function. the question i had in particular is, since my w/b is setup and works great were are the so called "brown wires and black and white ground wires" i need to tap into. every set of instructions i see seem to be lacking this. can anyone help me with this or chime in if you are running the same setup as me?

I did a bing search and found a bunch of links.

I have an AEM Failsafe UEGO but also saw some for the LC1.

This thread was extremely helpful with pointing me to the thread with the firewire build.

However, once I got the hard wiring done and everything was working with the gauge properly, I couldn't get the SCT LiveLink datalogger via the X3 to properly display the A/F reading as it was showing on the actual gauge.

Below is what solved my issue:

All the threads I could find didn't have the right formula needed to translate the raw signal from the AEM Wideband Failsafe gauge with Boost ( P/N 30-4900 ) to the SCT X3 so it can read the A/F the same as the stand alone gauge.

After banging my head against the wall checking and re-checking all my connections and grounds (non of which were any issue), I called SCT support line, whom were very helpful and friendly, and of course the tech brings up something I had not double checked; "What the AEM instruction manual specifically said about which formula to use."

Apparently the failsafe gauge is relatively new (circa 2013) and has a different formula than its predicesor, which several threads INCLUDING the SCT LiveLink software list as " (V*2)+10 This formula is so commonly used and appears in so many places, I didn't even think to double check if the manual stated anything different.

However, this specific gauge needs a different formula: (2.375*V)+7.3125 [I am running this on Analog 2 channel]

Even the SCT tech wasn't aware of this, so I gave him the formula to pass along to anyone else who might call in.

Also, since this gauge reads wideband 02 A/F and Boost, there is a conversion formula to datalog the Boost psi: (10*V)-16 [I am running this on Analog 1 channel]
