NA UTEC tune yesterday - dynos inside!!!
Got a chance to install and tune the UTEC yesterday on my car.
Mods are: Gruppe-M intake, Ultimate Racing high flow cats, Ultimate Racing Y pipe, Fujitsubo titanium exhaust, Unorthodox crank pulley. We have not yet swapped my heads over to the new 'crazy" setup, so these #'s are with stock heads, stock plenum, stock cams, stock manifolds in place. Everything on the car now is the same as it was then, save for the catback (I was using an Apexi Hybrid Megaphone exhaust then). I also have not installed the clutch/flywheel yet (OS Giken single plate) into this car. Spark plugs are factory originals with 41k miles on them since new (might start tuning with a fresh set of Iridiums next week if time permits).
Big thanks go out to everyone at ICS for working with me yesterday and letting me monopolize the dyno for the whole morning/night. Very nice guys and we are going to be doing quite a bit of developmental stuff with them in terms of tuning in the near future.
So onto the results!!!!
Baselines were done around 10:30 AM - weather stayed the same all day. After a lot of car talk, lunch, and a couple other cars visiting the dyno too, we wrapped up around 6 PM.
As a point of reference this is a brand new Dynojet machine (4WD model) - a bone stock STi runs 222 whp on this dyno.
Not sure how well these will scan, so if it's difficult to read, here are how the numbers worked out
Baseline (mods listed above and AAM flashed ecu): 242.34 whp, 236/16 ft/lbs
zUTEC Tuned: 254.84 whp, 241.26 ft lbs. These are SAE Corrected #'s.
Uncorrected: basline of 249.55 whp, 243.19 ft/lbs
zUTEC Tuned: 261.81 whp, 247.86 ft/lbs
The biggest difference from looking at the charts is clear though. After tuning, there are no spots in the rev range where we made less whp or less torque. The most prolific gains are up top, where the car needs it most.
The goals here were pretty simple - we want to build a database of workable NA maps that will serve as the basis for our tuning program to follow with our 2 in house Z's, as well as customer cars.

Next up - going to inspect my plugs, maybe try something else out, and get these new heads swapped on (just have to find the time, as we are getting to work on another one of my cars starting this week). Look for the results on the heads/cams in the next couple months.
So, what are my impressions? Very simple. There is no better bang for the buck mod than a UTEC, and IMHO, it should be the basis on which your future mods are executed. Whether you go NA or FI, nitrous, or not, a UTEC should be part of the equation. Thisis one of those mods that serves as the foundation for whatever your future Z plans hold. I am so excited now to finally get these heads/cams/headers on the car with the new clutch/flywheel
Happy New Years everyone!!

Sounds good. Where are you guys located at? I have pretty much all NA bolt ons and the AAM reflash and I am making very little power so I am definitely interested in a good tune.

the base map was pretty good, but my car asked for alot more timing advance. I left knock sensivity as it comes...I don't like to mess with it on any UTEC tunes we do. As a starting point though, it is awesome and off the bat made more power than my flash.

we're the reverse! Both our in house 350Z's are strictly going with heavily modded NA setupsand we are working with a few customers in various parts of the country on some NA builds as well

Will Know a lot more on Jan 18th as they plan a big dyno & info day that day.
So far they have not released it here as the demand from you US agents has been so great that all units made here in Sydney are exported

I think you might have misunderstood them then
The UTEC for NA cars relies on the stock MAF.
On the forced induction cars, you can purchase the MAP sensor, at which point it uses the MAF cor tuning zones in vacuum, and the MAP for tuning zones under boost.

Very close to the max of 5.0V.
A larger intake pipe with a MAF sensor opening, eliminating the plastic MAF housing was going to be an option but the MAP option has worked out cheaper
The big downside of the MAP option is dyno time, but once the map libarary has been built up this will help
Are the heads you have ready to put on the 46cc Nismo ones ?
If so I can assist you with tappet clearance problems

Yes my logs showed similar values for MAF as I recall - but its not worrisome to me unless I get to 5 volts
no I did not do the NISMO heads - bought a spare set of stock heads, did lots of porting, custom work on the upper, middle and lower plenums and a set of tomei cams. Hopefully we'll have them installed by spring

Does the UTEC come with a base map? I have heard stories about the UTEC sending to much voltage and frying the coil packs. Not sure if this is true, but that is what I have heard from some subaru drivers.

anyone who has experienced a coilpack go bad on a WRX has something off in their mapping. I've experienced it myself, so I know this very well
Yes the UTEC comes with a base map for intake and exhaust
