Hey guys, new to the forum and am having an issue and wondering if by any chance anyone else has seen this before.
This issue is on a 2018 Camaro SS A8.
Full disclosure I'm not using hptuners to tune, it's an SCT device with a tune from a company (don't want to name names) but they have never seen this before and their sole business is tuning with great reviews.
They sent me a flex fuel enabled tune and when I load it up my fuel gauge is usually at empty but sometimes will peg to full and then drop back down to empty when I have like a half tank. I'm getting two codes. P0462 & P2101.
We have done some troubleshooting and gone back to a non-flex tune and gauge works fine. Have also gone to stock and gauge works. Not sure what it is. Any ideas from the forum would be great, again just seeing if anyone has seen this issue before.
Right now I can't afford all that comes with HPtuners and want to get this solved for this device at the moment and will eventually move to HPtuners.
Thanks
