Hello All,
I don't mean to reiterate the same thinking, although i have just gone through the report for a 12212156 and I must beg the differ. Assuming that you are not tuning a stock vehicle, you must:
Throw in a reasonable timing map.
Get rid of as many variables as possible. http://forum.efilive.com/showthread.php?t=13021
Make sure the torque limit and traction control are disabled.
Set all of the changed hardware parameters.
Get car to idle(somewhat).
Use WBO2 and some method of applying changes(I prefer filtered) to: VE/IFR/MAF
After getting things close, go to dyno(steady state if possible) and setup the timing table. Start all over with fine tuning the AFR.
What gets me about many of these posts is: They reflect government politics... "We know what were doing, don't ask for specifics, you would not understand them anyway".
I say, watch the WBO2, watch for knock, and don't pin it's ears back for too long until you can make sure the first 2 are OK. This is not a trip to the moon, it's just wasting gasoline. Like anything, the better you get, the less waste you will create.
My 02,
