Ughhh.... anybody have an LS3/LS7 cartridge style MAF for sale?

Annoying thing is I got this car to avoid electronics problems and its biting me in the *** worse than my imports. My Subaru has free OS tuning so I widened the "PASS" voltage ranges from 0.0-16 V so they always read fine lol

Get your car retuned. The tune you have is wrong.

I agree, you should be able to have the maf code set with no cel and still pass

Fail code won't pass with OBD scan, doesn't matter if the light comes on or not.
Can EFI Live keep the MAF code in NOT READY status?

If I'm not mistaken, for the MAF, you should be able to turn off the SES enable light, which has to be done in the tune, you can't just clear it. A MAF code will not fail your inspection, but the CEL being on will fail. The system will still report the failed MAF, but you won't get a CEL.

One thing to remember, once you change your tune or clear the DTC, all of your emissions systems need to complete their tests and show a ready state or you will still fail the emissions test.

It's best to just tune the car so the evap and catalyst systems show a ready status immediately and just let your fuel system complete its cycle whenever it does. You could even tune that to complete immediately if you want to.

I use HPTuners for this, and don't know much about EFI Live.

It doesnt matter if you use EFI Live or HP Tuners if you dont know what your doing. EFI Live is not the issue.
