Wideband and SCT X4 Interfacing?
I want to install a wideband gauge in my 99" Cobra and would like it to feed data to my SCT X4 so I can get a more complete datalog. Currently I have Auto Meter Phantom gauges as they're the closest in appearance to the factory gauges I could find.. so if possible I'd like to get a Auto Meter wideband gauge. But I notice they're 0-4v vs. 0-5v. Does anyone know if this will work and what the equation will be? Here's the equation I think it needs, can anyone verify?
The Livelink datalogging equation will be a function of your BGD Hi and Lo set points. Your datalogging equation will be: AFR = ((Hi-Lo)/4)*V + Lo for example, if your Hi set point is an AFR of 20 and your Lo set point is an AFR of 10, then your equation is: AFR = ((20-10)/4)*V + 10 = (10/4)*V +10 = 2.5*V + 10 So the equation you put into Livelink is "2.5*V + 10" without the quotes.
