No A/F meter option on Trinity?

[darkZ]

Hello I have a 2008 C6 Z06
I just installed my trinity and I am trying to get my gauges set for data display.
I've noticed there is no option to add a A/F meter to my display.
Am I missing or overlooking something?
Or there really isn't an A/F option?
Please help.
Thank you

All GMs use narrowband O2 sensors. They can't give an accurate A/F ratio. They can just determine if its rich, lean or stoich. There should be a PID for an estimated A/F, but thats just a guess. If you buy a wideband controller and sensor, you can attach that to the Trinity through the Analog connector and it can read and display the ratio.

As Mike mentioned, you can add 2 analog inputs to the Trinity, heres some info on the process:

Where do I find this PID? Also on my predator it had an A/F data. So your saying that was an inaccurate reading?
If I had known I had to buy a wideband I would of not purchased the trinity.

sir, you're jumping to conclusions....

The Trinity will show the same pids, and more, that your Predator did.
The Equivalence ratio PID you were looking at with your Predator is NOT actual AFR, it is commanded AFR, and can differ greatly from what comes out your tailpipes.

If you want to see actual, real time AFR, on any late model GM vehicle, you need to add an aftermarket wideband O2 sensor, which is also perfectly doable with the Trinity.
