I always have issues with tables with no column headings, but I think I have the down now...
If I read it right you seem to be doing well. Good a/f, just a hair on the lean side. But you have to reduce MAF voltage by up to 10% to reach that a/f. Nothing wrong with that I suppose, but it is not what I'm used to seeing. Most folks start lean and need to add.
Were you running super rich on the OEM ECU fuel map?
Timing looks fine, with a nice progressive ramp towards redline. No knocks (that one count is a false).
Depending on your mods, I bet you go to a dyno to find out you will add maybe a couple degrees in the 5000-6200 range, and then not need a whole heck of a lot much more towards redline.
This is all amateur speculation of course. I could be way off. But your maps look like you're at or near the end of your fuel-tuning phase.
Rockin!

i will be adding the lower plenum, and pop charger if i decide to have it tuned at the shop. otherwise, i may try to do it myself...i just don't know yet.
i am having fun now with the utec....getting to know it better and better each time. still not confident enough to tweak my maps....so i am just going to log.
i have some maps loaded in with timing...but have not tried them yet. i may do that today or tomorrow and do some logging with those maps.
thanks for the positive feedback btw

Also, when you mess with the timing, keep an eye on your a/f as it also changes..
Your doing great and taking it slow is the right aproach.. Good Job..

Hey Road,
Looking good, your A/F does not look that far off.
What i would do is change your voltage to this :
5500 --- (-10.5)
5750 --- (-10.2)
6000 --- (-9.5)
6250 --- (-9.5)
6500 --- (-9.5)
Right now your looks like its reading this :
5500 ---- (-11.0)
5750 ---- (-11.0)
6000 ---- (-10.0)
6250 ---- (-10.0)
6500 ---- (-10.0)
This should richen things up just alittle bit and then we can go from there.
And once you add the other breathing mods you will have to add even more fuel.
Hope this helps

Hey Ace
What is your target AFR for those MAFv % offsets? And are you breaking out different Target AFRs across multiple RPM bands? Ie. 13.0 for 4k-5k, 13.5 for 5k-6k?
Just wondering what the the targets are behind your recommendations, so I may better understand them.
Thx!

Ok. Makes sense. The offsets you suggested at first seemed like big jumps given his current AFR and assuming a target 13.0. But it is good information that you've found 0.5 increments to yield reliable and safe changes.
Thx for the tip!

I am dialing in my a/f again, and have added timing from another map as a baseline. i did not encounter any knock, so i guess that is good and it did seem to run better...thanks mrc.
one question on timing...once you have entered your values, do you increase them until you get knock and then back off. not sure how to dial this in just yet but at least i have some timing in there.
i then dialed my a/f back in as it changed a little bit after adding timing. i am targeting 13.5 up to 5500 and then down to 12.5 to 6700. so far, it is going well...not too hard really once you get the hang of it.
pretty much comes down to getting familiar with the interface first and taking some time with the manual or other resources dealing with the utec; configure the utec properly for your application; do some logging with your stock setup (no utec maps loaded); evaluate your stock a/f readings and make SMALL changes to see what happens; get the a/f dialed in and start making some timing changes; dial your a/f back in once you have your timing dialed in.
of course, this is different if your boosted...please make sure you have a pro help you if your fi as this is a more complex environment. i personally would not even consider tuning my own car if i had boost...unless i was under supervision of a professional.
as someone once told me: once you figure it out, you will be like...damn, its not that hard
will post up more logs soon...and i haven't forgot about you either smokeytyrz...just been too busy tuning

here is a good question that i would like answered too and it was mentioned in here already:
how do you know what target a/f to go after and in what rpm range? with your answer, please explain why....or your references that gave you those parameters. i assume this comes with extensive tuning on the z's and these numbers have become the norm for maximum hp and most reliable...but just an assumption.
thanks all

note: this is too easy
lower plenum coming...may send pop charger back since it was damaged on delivery and i seem to be getting some performance from the stock box with k&n filter.
the 06 airbox is different from other models and imo has a better design. i got this from the dealer while i was getting a part for my pop and they had an airbox, z tube, and inlet tube there from on 06 that they never used. they put a CIA on that for the showroom and had 0 miles on my intake parts....cheap too...bargain pricing because new nissan parts are way overpriced.
i also added a samco hose that replaces the z tube...really nice piece and smooth inside, without any corregation, and the attachment hose is built in there really clean. z-1 performance is the only one carrying it right now but it is really nice.
rw...out

no pics yet...will and yes on the laptop road tuning. i wish i had access to a dyno for free. the logging part is kinda scary because you are definately breaking the speed limit...unless your on the autobon

The only dyno in my entire state is about 2 hours south of me and charges $100 per hour. As many pulls as you can make. He JUST opened and is looking to get his name out there. I'd mention the shop's name, but i'm sure i'm the only one on these boards in the Dakota's..... Stupid military.

Closest dyno to me is about 30mins away. Might be heading down this week or next week to test out a few more mods i have done.

closer...from 4750 up good
my own tune, different application and with timing...still need to work on the lower half 
Code:

i need to work on the timing....those are utec map numbers but i am going to add more in. i have some other numbers to plug in and try...its trial and error without a dyno. 
one thing here, its a PIA to log, tune, log, tune, etc
however, its the best thing i ever spent money on...it is very time consuming and rewarding
