[QUOTE="MrCaliKrome, post: 13745037, member: 143875"] [COLOR=yellow]This thread was extremely helpful with pointing me to the thread with the firewire build.[/COLOR] [COLOR=yellow][/COLOR] [COLOR=yellow]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.[/COLOR] [B][U]Below is what solved my issue:[/U][/B] 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), [B]I called SCT support line, whom were very helpful and friendly, [/B]and of course the tech brings up something I had not double checked; [COLOR=#ff0000][B]"What the AEM instruction manual specifically said about which formula to use." [/B][/COLOR] 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. [U]However, this specific gauge needs a different formula:[/U] [COLOR=#0000ff][B][COLOR=yellow](2.375*V)+7.3125[/COLOR] [/B][/COLOR][COLOR=#008000][B][I am running this on Analog 2 channel][/B][/COLOR] 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 [B]Boost[/B], there is a conversion formula to datalog the Boost psi: (10*V)-16 [COLOR=#008000][B][I am running this on Analog 1 channel][/B][/COLOR] [/QUOTE]
