So I spent the better part of 6 hours in my car today trying to figure this out.
The answer I still haven't gotten from anyone is if this is normal or not with a MazdaManiac calibration.
I went back to the stock tune (by uninstalling the AP) and data logged and at WOT I get 100% calculated load. That's fine. I did the MAF calibration selection process again (these freaking trims are driving me crazy!) but I got to another calibration that seems okay. However whenever I datalog with any Mazdamaniac calibration I cannot get up to 100% calculated load. My calculated loads vary between 87%-93% at WOT (peddle all the way to the FLOOR) and my AFRs vary widely.
I'm going to give it another day and then do another set of data logs and just send it to MM as is. Maybe he will notice it and answer it via e-mail. I just didn't want to prolong the process if it's something I shouldn't be worried about or if I'm doing something blatantly wrong.
Anyone?

I'm using v1c_4a. This is WOT 3rd gear. I would like to reinforce the fact that I am not lifting my foot off the throttle AT ALL until I hear the redline. (Logging on my stock tune with my foot all the way down the LOAD is pegged at 100% all the way through) Notice how my load varies up there and my AFRs are nuts.
I will try the Cobb "stock tune" tomorrow.

i haven't been keeping track, if I understand correctly (from the last few posts) for NA maps there is a current issue with it being at 11.1 AFR at WOT because of a software issue and we're waiting for cobb to push a fix?

Current tuner software makes it run very rich...Jeff has gone back to a previous version of the software that does not have that issue.

SWEET!!! quick question jeff.. my LTFT was at -5 on the No trim map and i switched to map MM YYYYs TT AA vXx_4b.ptm
now LTFT is 2
STFT is -0
My logs were based on the No fuel trim map
do i have to log once again and send them to you???

i'm wanting more people's feedback to see how its working out there in the world as my car can bearly hit 160 rwhp on current logs while my old logs from a few years ago hit 205rwhp

Okay Jeff so here is what I got today. I logged WOT 3rd gear runs of both the Cobb "stock" tune and v1c_0. They speak for themselves.
As you can see with your calibration v1c_0 the max calculated load is ~85%.
On the Cobb stock tune I was pegged at 100% pretty much the entire way through, that little dip you see at 6,000rpm is when I went over uneven pavement on the highway while data logging so my car jumped a bit.
I don't know what to think. I did make this out though As I'm going up the calibrations my max calculated load increases. I tried v1c_1a after this and my max calculated load was ~90%. Then you know on v1c_4a and 5a I'm hovering in mid 90%'s. I should add that my car performance wise is completely stock with the exception of my Borla catback exhaust.
Another thing I noted while going through the MAF calibration selection process again (NOT today). This is how I've done it. I warmed the car up with the AP completely uninstalled (180f). I turn the car off. I load v1c_0. I turn the car on. I look at my STFT - it's "off the scale" as you mention in your first post - at something like 15-18%. HOWEVER this varies. Like the last time I did this process. I did exactly as I just said but when I turned the car on with v1c_0 my STFT would be at -1 to 3% and it settles back to 0%.. so that is bang on what I want correct?.. Then I realize my load is still all wrong.. so something else has to be going on, so I do the process AGAIN with v1c_0 and check my STFT and it'd be at something like 10%. Whenever I try the MAF selection process again I completely uninstall the AP.. so it's not like I'm going back and forth between maps and checking my trims each time. I just thought I should mention this since maybe it shows something? Idk.
Please tell me you have an idea of what is going on. I am open to any suggestion.. if you want I could walk you through exactly what I'm doing over the phone.

BTW - I can't use your spreadsheet tool.
It always give me some error about the wrong data, even though I've tried to hack up the logs to look like what it is looking for.
Just a hair too lean in spots. The spikes happen from time to time, but I will see if I can address those.
Why would you log with the wrong calibration?!?!?!
The MAF flow is the same.
Load is a calculated value. It doesn't mean anything in this context.
"Off the scale" means 22%.

So are you saying I should just go forward with this? The -calculated- load maxing out at 90% isn't going to throw off something in the future? Logging? Further tuning attempts?
And what calibration would you have me use when I'm at 15% STFT on v1c_0 after starting the car up for the first time post flash (warm engine)? v1c_5a?

Jeff, do you think maybe there is something wrong with the maps you sent me? I mean noone else has this problem and my application is bone stock NA... Do you think you could send me another set of base maps to try it with? Just to see if this problem exists there also and maybe we can work from there?
