I want to go MAF less... how do I tune it??
I want to go MAFless...
I have HPTUNERS.
I want to know what I need to look at and in what order....
do I just unplug and turn off codes and SES?? then start doing tuning just the same as normal...??? or do I modify different tables???
and fine tune with wideband???

It's covered in a few topics in the main sticky
since you have a 2000, you'll be modifying the secondary VE table...
You can unplug the MAF or disable it in the PCM... both are covered in the VE tuning doc,
You use the wideband for wot tuning, the stock O2s are fine for normal driving .. .unless you want to make an open loop only tune

i have mine in SD right now, maf is off the car.
my changes were made to the primary table and they worked, i never touched the secondary?! i went back and made both the chagnes the same in both tables. but from what i saw i think in SD it pulls from primary, i might be totally wrong but i made all my fueling changes at first to this table, and i saw my trims go to 0???
