Default Learned something today (SD Tuning)

Well, I figured I would post this since I couldn't find anything on the topic. I reflashed my car with a new tune and for some reason the car wouldn't idle, and the gas pedal wouldn't even do anything. It started up fine, then it just wouldn't run at all.
Well, aparently, if you set the MAF codes (P0101-0103 I belive) to Type X (no error reporting) it makes the PCM's code crash and the car doesn't run. I wasn't paying full attention to the part in the autove tuning tutorial where it said set the maf codes to No MIL.

Just a bit of future reference for everybody.

yea, gotta have them enabled (but can have them setup to now show the SES light)

Otherwise the PCM doesn't know to failover to SD mode

If you decide to run SD full time, set the maf codes to non-emmisions and mil to no-mil.
