Failing the MAF for VE Tuning
I've been trying to find out how to fail the MAF so that I can tune my VE table and for the life of me I can't find any table relating to MAF failure limits under the airflow tab and there's not a airflow tab under the engine diagnostics table either. The car is a 2002 Z06 and below are a few screen shots of what I'm seeing in HP Tuners, any help would be appreciated, thanks.

In order to do SD tuning you must dis able the MAF reporting otherwise you will put the car into a reduced power mode and the timing will run in the low octane table only
To dis able the MAF the proper table is in the "diagnostics section" of your tune You have to set the fail frequencies to the max and min values so the MAF does not report---Also we were taught at EFILIVE to copy the Hi Oct spark table and paste it into the Low oct table so the timing isn't altered-

I just did this and discovered knock learn factor gets stuck at 0 once you're done. So have to keep high low tables equal for a bit before it gets back to 1. Not sure if there's a way to prevent this.
