Calling wideband and datalogging experts

I'm bashing my head here trying to figure out why this isn't working, I have my wideband gauge and computer hooked up, groundings are good and power is ran independently, when I'm in neutral and the gauge reads 15.5 so does the computer, but when I rev the car and the gauge reads to 10-12 the computer is still reading around 14.5

Any ideas to this, it is infuriating.

What gauge are you using? It sounds like your analog equations are off. Are you using a SCT programmer and LiveLink?


What does your dyno sheet trap?

That's what I thought but then if they were my idle numbers shouldn't be matching up right? Cause then if I lower the equation (v*1.65)+7.35

It will make it read less than the gauge at idle.

Your multiplier is apparently off. Which wideband and specifically, what sensor, are you running?

Ah, the lovely LC-1 with a Bosch sensor.

Here's a decent walkthrough on correcting the ground offset via a custom equation.

LC1 setup (ground offset)

^ I was trying to look for that, but you beat me to it.
