When I get the AP I would ideally like to see the following
WOT: low 13's never above 13.5
Cruising partial throttle: low to mid 15's
Cruising mid throttle: high 14's low 15's
Although none of this is concrete considering the load the car is experiencing at any given time.

MM,
So am I OK with the reading's I'm getting? Map in use is 1b_0
AFR of 11.2-11.8 at WOT, and AFR's of 12.5-13.5 at light throttle above 5500 RPM, Idle AFR at 15.2. Cruising bellow 5K saw AFR of 14.7, but when I get on the gas lightly and work my way to redline the AFR's drop to mid 12.5-13.5. STFT was at -1 and LTFT at -2. What's my next step if these #'s are good? Do I go to 1b_2b due to the combined STFT and LTFT of -3 or do I just drive this map for a bit longer?

They will constantly adjust and often in completely unpredictable ways.
It is, for your purposes, completely meaningless.
We only care about the STFT in the first couple of minutes after a reflash and the LTFT after a day or so.
Then, you needn't look at them again.
BTW - I am on the road for the next 12 days, so I will be very slow to respond to stuff. Sorry.

turrrbo!
iTrader: (4)
so MM since my LTFT has been at 4 for a while now, i should just follow your instructions and move to the next appropriate map correct?
And if a LTFT of 4 is negligible, will you give me the stage 2 maps if i shoot you an email?
thanks for the help, sorry if i'm getting annoying =D

MM,
Thanks, the only reason I asked is that in your instructions on the first post you mention high load AFR of 13's not low 11's. Your the expert so I will stay at this map for another day then go to 1b_2b. Just for clarification you also mention to contact you if I'm running to rich or to lean. Lean I know is above 15 but what do you consider to rich?

I looked at the engine load and it said 38% while in third gear at 5800rpm, AFR read 11.9-12.3 during this. I'm assuming this is normal since MM said my #'s look good. The only reason I was questioning my #'s was because I was under the impression our goal was to see mid 13's at WOT.

Also, for anyone with four seasons, if one had homed in a map during colder season, is it reasonable to say that we'd have to back off to a less aggressive map for the summer?

So if I understand this correctly, for optimal performance with minimal risk we want to be in the mid 12 to mid 13's at WOT or high load? If so what does 11.2 at WOT do for performance since that is where I'm at? Being that my LTFT is -2 I will be moving to the 1b_2b map which removes 2% fuel, so is it safe to assume that my AFR will increase a bit from what I'm at now? Man this tuning stuff is complicated but fun.

The first post in this thread says:
The trim stuff is for initial fuel trims so the car isn't off by much when it's reset. The stage1, stage2, stage3, etc type stuff is what adds or leans your fuel.
Once the idle trim is correct (a few % one way or another is totally no big deal - in fact, up to 12% is acceptable since the PCM can go up to 22% before it starts to struggle), drive around in various conditions less that high load and see if the fuel trims stay within +/-6% or so of the idle trim. If so, you are good to go!
Watch your A/Fs at high load. If they start to swing too lean or too rich, you must contact MazdaManiac for adjustments.
You should be seeing high 13's in some conditions, mid 13's in most conditions and high 12's in others.
