Default Turning off MAf codes?

Can i just turn them off so i dont have to see the SES light? Will it affect anything else if i do that? I know the PCM will run on the secondary VE table and Low octane spark tables. Juyst wondering if there are any other adverse effects it will have.

yeah thats all you want to do is make it so you don't SEE the cell...if your trying to go into SD you want the test to run & fail you.

On some 98-00 operating systems with automatic's the pcm will command max line pressure...there are a few on/off switches that need to be adjusted for this. BUT since your an m6 the items you mentioned are the other main things.
