00vi 15.1@91.8
Finally went back to the track after installing my 00vi back in march. I will note that I did go to the track a few weeks after installing my full 00vi swap. I made three passes, three were 15.6@ 93.7 and the last pass I made was 15.7, though I can't find that time slip. About 1/4 tank of gas, no rear seats, spare tire, & jack. I was untuned on de-k injectors, the power rod was not connected properly, and I was having issues launching. (2 step was activated on the EU but I was attempting to launch slipping the clutch off of idle, resulting in the EU cutting power until I got rolling, thus turning off the 2 step and spinning the tires from the sudden burst of power.
Fast forward to last Wednesday. Differences from the 15.6 passes: power rod opening at 5000 rpm, 2 step deactivated, roughly tuned to high/mid 13 afr, replaced sri midpipe with stock midpipe, and replaced 2.25" catback with 3" catback. Roughly 3/4 tank of gas, no rear seats, spare tire & jack. I made a total of 11 passes.
Best run of the night was 15.1@91.8 (Run 7)
Density Altitude was 2342 at the time of my 15.1 run.
Time slips below.
My tune and my launches still need work, and I'm due for new tires soon. I think I covered just about everything...Comments and criticism is welcome.

Well you already know your 60' needs significant help. More practice is definitely in order there.
About the car itself, you said your car is tuned to mid-high 13s. That's too lean. Right around 12.9-13.0 is where you want to be. I assume since your AFR is not really tuned that means you haven't done any timing changes either, correct? Also assuming you're not using the extended rev limiter?
Lastly, do you have a Y-pipe? I would assume you do, but I didn't see it mentioned in your post.
If you're using stock timing and no extended rev limiter and have no Ypipe you could easily be leaving 30-40whp on the table. That would transform your car from a 92mph car into a 98mph car which would be much more in line with what I'd expect to see from a car with your mods. Of course those traps are good for mid-low 14s if you can get the car off the line reasonably well.

I am tuning with Emanage Ultimate.
Update:
Well I went back to the track earlier this month, and the first few runs were 16.0 @87/88, full interior inc spare and 3/4 tank of gas...doh. Anyways afr was down to mid 12's on the same tune I ended with in the OP. Made a few runs and leaned it out to low 13s/high 12s. Made sure that was stable, then gradually advanced the timing 11-13 degrees from 3k to 6.5k. Overall timing is 28-30 degrees at WOT. When all said and done, I was able to shave off 0.6 second and gain 4mph from advancing the timing. I'll scan the timeslips and upload them in a few days.
Mod changes for these runs were stock 5th gen airbox/snorkel with k&n filter and RX7 wheels.

It really is just an average 12 degree advance over stock. Going through some threads on here, I felt it was a good number to start with until I can hit the dyno. I'll see if I can find the threads again.

Dude 12* is a LOT of timing to add. What octane? Even on e85 that would be a lot of timing.
Remember just because it's not knocking doesn't mean it won't melt. Seems like way to far of an aggressive tune.

Okay I spoke too soon, I didn't mean 'just 12*' as if were a minor change. I agree it is quite a bit of timing to add. I'm running 91 octane, the highest available to me in Arizona. I agree it is an aggressive tune, but I think the only way to determine if it is too aggressive is dyno tuning. I wasn't able to do much testing to see where the limit was, whether it be knocking or slower ET and/or trap speeds because my laptop ran out of juice after a good 3 hours of making passes down the track and adjusting the tune.

You really need to go on a dyno and rent it out for an hour or pay someone to tune it. See where your peak torque is at that will help you with what your timing should start at. IIRC
I'm not familiar with emanage but I am familiar with tuning, any screen shots maybe I can help you out some?
Something doesn't make sense if you are running that slow and have it leaned out a good amount and added timing.

Something more like 25-26 in the lowend, 24-25 midrange (3800-4750 range), slowly rising to as much as 27-28 by red line will probably work better for you. 28-30 in the midrange is definitely asking for knock and not likely to gain power, although each car is different.

A dyno tune will be in order after I get headers and pftb installed.
Thanks guys, thats the information I was looking for. I'll retard the timing a bit and see what my butt dyno has to say, as well as 20mph to 60 or 80mph times.

Yeah I know, but a 3rd gear pull isn't happening on the street/freeway.

Thats actually quite a bit of stuff, you can tune fairly well with those things.

First one is the tune I ended with on the track in January. Timing seems to be a bit more advanced on the top end than when I left the track.
Yellow line is Ignition timing. White line is AFR - The line that marks 21 degrees of timing also marks an AFR of 13.2
And here is after I pulled a few degrees of timing. No changes were made to the injector map, I was a bit surprised to see a change in AFR due to retarding the timing alone.

Last dyno day was this past summer. It was about 85-90* outside and on a mustang dyno she made 452hp to ALL 4 wheels. 29psi, e85. I just converted from Maf to speed density that morning and did 2 street pulls, for some quick adjustments and slapped it on the dyno. Had I taken the time to give it a a few more pulls I know I could of made 500hp easily.
This dyno reads pretty low too. The tuner (who currently has an 8.80 -8.90 talon) said any car he has tuned, (evo/dsm etc) that has made 400hp on this dyno has a 10sec car.
I tune on www.ecmlink.com it's an eprom chip on the stock ecu. I have had been tuning on ecmlink (formally known as dsmlink) for about 4-5 years.
This is by far the best tuning tool on the market for the dsm. If they could do something for the maxima forum, omg the possibilites are endless.
