Custom Tune after Mods - Checking AFR - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Hey guys, hope you're all doing well.

So I installed a CAI, headers and removed the cats. I also ordered an SCT X4 and Dyno Steve sent me a custom tune.

Before he was able to send me the custom tune, I loaded the one that came with the SCT, and went and had it dynod.

With the tune that came with the SCT, I took it to the dyno (since I was still waiting on Dyno Steve) and saw that the car was running pretty lean. Around 13.5 or so, full throttle, according to the graph.

But I just received Dyno Steve's custom tune and loaded it into the car. Honestly, it does seem to be running quite a bit smoother, but that could just be in my head.

My question is, can I view the AFR using the SCT X4? I know the best way is to actually check the exhaust, which they did at the dyno. But the dyno is pretty booked and I just want to make sure I'm not running crazy rich or lean. I'm definitely going to take it to the dyno again, but just want to make sure I don't hurt the motor while I wait.

I recorded a datalog using the SCT, but can't see where to view AFR in the LiveLink program. Sorry for being such a rookie, but this is my first car that I'm actually adding mods to.

Any advice would be greatly appreciated. Thanks all.

Ahh, cool thanks. I guess those just replace the O2 sensors, and now I'll have that as part of the data on the SCT?

No. You would have to have a way to wire it to the SCT, which is does not have. The wideband doesn't interface with the car or obd2 system. You would need to run it to an external logger with an analog input. HP tuners has this option, so you can log AFR into the software. I've never seen a SCT box with that option.
