Flex fuel ?'s on '21 ZL1
I have done this with success on my previous '17 ZL1 and '18 Silverado but have problems logging the commanded air/fuel on my '21 ZL1. The sensor is definitely enabled and reading the ethanol percentage but I cannot see a change in the commanded air/fuel. Yes, I have the stoich table set to the corrrect values for alcohol. Am I not logging the correct value as there doesn't appear to be more than one commanded air/fuel parameter? Any ideas or comments would be helpful...TIA!

Are you using the BETA? Even though it's quite late in the year, I've had issues when I don't use that sometimes. Have you kept-up with updates?
I'd select all of them, and see if you get any feedback. Are you using SAE? Which interface are you using?

I performed the most recent updates from HP tuners. I am using the old wired MPVI interface. Not sure if I'm using SAE or not...it is possible fueling isn't adjusted until power enrichment mode. I ordered an AEM OBD2 gauge so I can log air/fuel and see the value on the fly. Thanks for your response. Many of the logged parameters are "greyed out" and I cannot select them when attached to this Camaro. I know it is something simple but not easily resolved with a right click or select in the desired cell.

If a lot of the PID's are grayed out try repolling parameters after connecting the scanner.

In the past, I've had trouble with getting some channels reporting correctly in the Scanner. I reached out to Support, gave them what they wanted, and they were able to fix it. Surprisingly - it wasn't a new issue for a car that was that old, and they told me they applied the correction to the next BETA. I wasn't the only person here having that issue, so credit goes out to him to point me in the right direction. SO - if you continue to have issues after repolling, as suggested, reach out to Support.

Also - I don't know if this could apply, but I know that having too many channels open can sometimes result in not getting channel data. I've read posts where people were trying to get GMVE going, but it wasn't reporting any data. They determined they had too many channels open, so they closed enough to get the GMVE going. I've seen people run with a crap-tonne of channels but it's probably best to monitor only what's necessary. This might not apply in your case, but just in case, I thought I'd add that.

Cool I will try to repoll... I suppose that is under the help pull-down? I only have about 10 items on the list open so I don't think that's the problem but I understand why you're saying it. Thanks!
